99 Camry 250k miles - Performed disconnect test, both fans shown good. Replaced brown fan relay taken from junkyard, both fans spin --FIXED..! $0, 10 min, no swearing. I LOVE YOU..!
Thank you for your video on over heating Toyota Camery (1997 -2001). My son in law and daughter were quoted $1400 to replace the radiator, fans, thermostat and hoses on 2000 camery only worth $1200. Using your video we were able to prove the fans were operational and narrow it down to the three fan relays which we replaced for $73. Overheating problem solved, and your video saved them from having to replace their auto. Thank you soooo much!!!!!!!!!!
I greatly appreciate you, I thought it was my fan from the beginning, but when you showed me the fan trick, it then, was confirmed..... Just left pick n pull, for $40 I'm back on the road.👍💯
Thanks I just changed my thermostat because it gave me problems last winter with not heat put a piece of cardboard in front of the radiator to have heat to get to a Doctors appointment. That work fine . So I have been watching this site I love it. I am a 72 year old male, and still working on cars.
I understand that. Im not too proud to say ive used the cardboard trick before too. I still keep some around for a lot of other stuff too. Just as handy as duct tape and pieces of old 2x4's. Cardboard is your friend LOL. Glad to here you can still turn a wrench Im 54 now Im eating right and exercising 5 days a week hoping I can still turn a wrench in my 70's. I wish you another 30+ years of wrenching my Burnt bruised and bleeding InSaneFriend
My God dude I just replaced my radiator and coolant temperature sensor only because I didn't have the tools to test my fuse and this helped me out so much
Great tips. I'd check the fuse first, then the relays. Unplugging the sensor connection could save buying a fan, which is what I was just going to do. (My ex wife in another state has a Camry, and the A/C fan comes on, but not the thermostat one, leading to the car getting hot when sitting in traffic. My son should be able to check that out, based on your video. Thanks!
Thanks, good info. For limp-home mode (cold weather, 40F) I pulled that connector to enable the fans and then pulled one relay so that only one fan was running (so it didn't overcool). I'll test the fan thermoswitch later (when replacing the radiator which seeps coolant at the top tank).
Having exact same problem. I also did notice that touching1-2 smaller relays started the cooling fans right up. I’m ordering a relayed sensor tester to check
Ok, bought my daughter a 97 Camry with 179,xxx miles the other week (knowing it needed a couple of things done to it that I am more than capable of wrenching on like new struts, brakes, sway bar bushings and end links) and the 5SFE 2.2 had the original factory thermostat stuck open, as it was running very cold and the temperature gauge mainly stayed pegged on C while driving (outdoor temps were 0°-20°F) and would climb about halfway up to normal when stopped at a light. I replaced the thermostat with a new OEM one. Now it comes up to normal operating temperature on the gauge (confirmed with both an OBDII scanner and an IR gun to the thermostat housing) and holds there, but the radiator cooling fan doesn't come on at all (ambient temps have been 45°-65°F) even with high speed runs out on the highway followed by prolonged idling in the driveway. (My 95 Camry with 5SFE engine will kick the fan on and off when idling for prolonged periods). I watched your video, with the lower radiator twmperature switch plug disconnected, both the engine cooling and A/C fans operate. All three relays can be felt to be engaging. No change from wiggling, both fans run. Pull #2 relay and engine fan quits. Reconnect lower radiator temp switch, both fans quit. Turn on the A/C system and both fans operate. I replaced the lower radiator temperature switch with a known good used one and the engine cooling fan still does not operate. Pulled the connector apart again on the top corner of radiator and both fans came on. Jumpered the two female terminals in the harness plug and the fans went back off. Went to the temperature switch (two terminal, green female connector) mounted next to the temp gauge sender in the upper radiator hose elbow on the driver's side of the engine and disconnected the plug. No change, fans did not run. Jumpered the the female plug, nothing. Both the engine compartment 30A fuse and the dash panel 7.5A fuse for the fans were/are fine. I'm stumped. Is there a wiring issue to the engine (upper radiator hose elbow) temperature switch? Do I need to replace both the lower radiator and the elbow temperature switches with new OEM switches? I currently have the lower radiator switch harness disconnected to run both fans constantly, as my daughter's daily commute between her apartment and both jobs entails a lot of stop and go driving across town and back and I don't want to run the risk of overheating and toasting her motor. Suggestions?
HI there, did you solve the problem ？ I encounter the same case. I guess it might be relay #1 or radiator temp sensor, though 2 mechanics changed them before.
@@hubert408 Yes. The system was operating as it should! The coolant temperature just wasn't hot enough to close the temperature sensor! Once summer hit, it would cycle on, and when the A/C was turned on, the second fan would kick on, regardless of ambient or coolant temperature.
@@ProvacativeAcorn I am pretty sure that the problem is with radiator sensor. We have 3 temperature sensors: one for engine, for I can read engine temp correctly so it's good. one is called gauge sensor for display only. it's no the problem. Only radiator sensor might cause the problem. Another thing I excluded: all relays work for I can see both fan can turn on.(unplug the radiator sensor cable, both fans would turn on.so control circuit is good) But because some mechanic changed the radiator sensor , my friend believed that sensor should be good. I finally don't know what's the culprit, though I still think the problem is with the radiator sensor.
Hi. I got off the couch and got dirty.. I have a 2001 Camry USDM, it's the only one in the Philippines, I think.

Great video thanks brother . Did you switch relays and still have the same problem ? I have seen a kit out that you can test them. I think it's called a relay buddy not sure of that . I just know that you can take a relay and plug it into the tool and it runs a test on it . I do believe that it comes with test relays so you can plug it into the car and check the circuit . Keep up the great work see you in the next video thanks again brother . I do like the old school ways
Leaned a few things, though my car is older. Must say though, I found the music to make the video almost unviewable. You don't need the music. Thanks for the tips!
Thank you for your comment and views. Your right. Since this video I have switched to Davinci editing software. I have much better audio control now. Most of my newer videos have much lower volume music or no music at all.
Thanks man I wish I had filmed even a tiny fraction of the repairs Ive done. Thats how I got started on youtube. Heres my repairs playlist th-cam.com/play/PLADlyv_PN7XJpaCV0OeFG8Frm1240FsET.html
Hello im having the same problem. I changed my thermostat, Relays, fanswitch, tempswitch. The thermostat opens and gets hot so i know the radiator is working. Idk what else could be causing my fan to no turn on.
Your video has a very similar problem to what I have going on when I turn the blower motor for the AC on the fans run but when I turn it off with the AC the fans turn off and never come back on except without turning on the AC plus the radiator fans don't turn on high
Great video! So my question is when my engine gets hot my cooling fans do not turn on. But when I have my ac on both fans work fine. What could be the issue
Nice video... I swapped the engine on a 2.2 lt that was running good. But now the engine that was swapped is overheating...but I noticed that my fans ain't coming on...I'm gonna try this tomorrow thanks!!!!!
My fan come on when I turn on the air machine hey want come on with air off.why I set a while start running hood.I replaced the number 1a I’d three relay.I’m having a heck of a problem.your video was really helpful.
When I unplug that cable the fans do not turn on even when the AC is on. The fans don’t turn on when the engine is up to temperature. I checked the resistance of the engine coolant temp sensor on the bottom of the radiator and its reading 7 ohms. I know when its a cold, the engine should be reading 5-6k ohms. I tried bridging the connection of the disconnected wire to bypass the sensor to verify everything else worked and it still did not work. I replaced all the relays and checked the fuses inside and didn’t see any issues. I connected each fan to the battery and they both worked so I am stumped on what else it could be.
This is really informative, thank you Can anyone help me though, I have the opposite problem of this video! My fans are running all the time even with the car off in the key out!
@@saneautohi i have not yet I actually thought that was probably going to be eight implant to get one tomorrow, or check it However, I then remembered that my right tire went over a curb and something scraped a little right before I noticed the fans staying on all the time when I turn the car off! So, I'm thinking it's probably the sensor on bottom passenger side of radiator
Hi there, Inhave a 2000 Toyota Sienna. The fans only come on when the heater is turned on, when the car is left to idle the fans never kick on. This causes the coolant expansion tank to keep filling until it over flows spilling out as the liquid expands from the engine heat.. There are no codes or check engine light. There are three fan relays back to back just like yours with a brown one in the middle. However the fuse cover doesn't indicate a "Main" fan relay like the large green relay on your camry. There is a large black one that just says Main.
This video helped, but not with my similar problem. The fans wirk when the AC is on, but not when the car gets hot to cool the radiatoe. I tried a new relay for fan #1, but it didn't work. The dan kicked on for less than a minute after trying the new relay but went off again. (The heat doesn't work, (the inside fans blow), but did when the fan went on)
I have a Toyota Camry 2000. My radiator fan only goes on when the air condition is on. I troubleshoot the relays and electrical system. A ok. But the fan does not go on if the air condition is off.
97 Camry v6. Fans inoperable at all times. Fan motors tested and work independently. Unplugging two wire fan switch at bottom of radiator does nothing. Relays check out fine. Thermostat and water pump fine. What else could be issue. Ecm?
This might be a dumb question but do these fans only come on when you turn the AC on? Or are they always supposed to be on so your car doesn't overheat?
they are supposed to come on and go off when the radiator gets hot, regardless of whether the AC button is lit up green or not.... but my radiator fans only come on and off as intended when i have that AC button pressed and lit up... if the interior dash blower fans are off and the AC button is not lit green-- my radiator fans WONT COME ON.... ugh...
Did you make another video? My original problem was that the oil pressure light on dash was showing up as on but only after engine got hot, and sat at idle. We hooked up a Harbor Freight oil pressure gauge up to it, but it said good oil pressure. Turns out, my fans we're not turning on whenever the engine got hot, causing oil to run thin, causing less pressure (I think that's how the physics should work????)... I replaced the upper radiator hose, thermostat, radiator fan switch(sensor) below the radiator, and the green engine coolant temperature sensor (2 terminal/green one) next to the block. STILL nothing. Fans will NOT turn on. I just ordered the single terminal OTHER engine coolant temp sensor on Rock Auto to see if that will solve the problem. I will report back. Also, I'm not sure if this has anything to do with it, buy my AC doesn't work, but when I swap relays, it will work for a month or two. Then I have to buy another relay. Any advice appreciated. Thanks.
OK I have a 1999 camry. Unplugged the connection on the top back side of radiator and fans still didn't come on. Unplugged fans and straight wired them to the battery and both worked. Any idea what the problem is? Thanks.
Could be a bad fuse. On toyota 1999 the fan fuses are most likely labeled rad and cond. Short for radiator and condenser fan. Checking the fuses may lead to some info.
Not exactly my issue but I did have that one . Did exactly what u did... It worked. Now I have ac issue. My car guy here in town seems to think it the Head? Controls in car , ac button ? Need advice. Like your down home style. Thanks sane car man. Hot in Hot Springs AR
I love this video very informative! Straight to the point! Have the same issue with fans running all the time so I’m changing the relays first then fuse then temperature sensor but first I drive it for a while to see which one fixes it first will post an update
I no this is very basic but it'll definitely keep the parts cannon from coming out in a situation like this. My problem was on a 2003 solara and the fans were not coming on. Turns out the the ECU-IG fuse was taken out. My gf was trying to make the clock work again & was confused on the fuse order in the panel as it relates to the diagram. So b4 u do any thing verify power by ensuring all fuses r n place etc
I have the same car and year, same set up. my problem is fans do come on with aircon, but I'm worried the heat sensors you point to on the pipe are not working. Is there a way I can test with engine cool? I(ts summer here in New Zealand and it get mighty hot. Your video is so good and and you explain things well. Thanks you, Marc
Amazing.. Is it fan motor connect with dasboard meter? My dashboar awlays on and off repeated while driving, if meter going down, my meter running down oso...
both fans run with sensor disconnected can hear all relays clicking but wiggling relay does not start fans.. wahts the next test to diagnose problem if I am interpreting this as not the fans not the relays ?
My sons 2001 camry has this problem..fans working but only when heat is turned on...must be a fuse..right? Already replaced both temperature sensors on top of engine.
2005 Buick Century cooling fans not working. I hot wired the fans, both worked. Replaced 1, 15 Amp. fuse. Replaced relays fan 1& fans. What next, check for broken wires. What about the coolant temp. sensor? 10:0310:03
Yea, make one more in depth on this problem. I did that test and both fans came on, then went to the relays and the fan2 did have an issue but I didn't get fan3 to do anything so not sure what else to look at other than replace all three relays.
@@ProvacativeAcorn I replaced that relay on fan2 and also replaced the temp sensor at the thermostat. It's usually the temp sensor that goes bad. So start with the relays but it doesn't hurt to replace the temp sensor as well.
Hey Sane. My passenger fan wont come on after I pulled fan 3 relay out. It was very hard to pull out and plug back in. It was running when I pulled it out
Both fans are out i think its main relay switch fan #1 I can hear #2 switch but not #1. Could there be another problem that would cause both fans not to turn on.
I got the same problem, I change ,thermostat, water pump, timing belt all rellays, all sensor all fuses and fan still don't come on what else I can do thanks
Got a 96 Camry the car is doing the same thing as your car is doing in this video is there any more testing that you can do to get the fans to work we wiggled the relays that seems to be fine I feel the clicking on the 3 relays so we are in need to get this fixed or do you have any more videos on this thank you for your time and help
So I have a check engine light says temp sensor I've changed all 3 sensors my fan doesn't seem to come on at all car stays same temp about medium heat lmk if you can help thanks
So, did you replace the relay on the fan that didn't come on? Cause my 92 camry only turns on one fan when hot(the same u spun with the orange relay) but the other doest not come on, only with the ac switch and just then both come on
Yes hi. My problem is in my 2000 Toyota solara my fans constantly run not when the key is off but when you just turn the key on the fan to run so the car always takes a long long time to warm up so I was just wondering what you might think that could be as well I'm sure it's on the same line as maybe the relays maybe I don't know but the fans always run constantly. If you have an idea please let me know thank you
Hello I have a 2001 Toyota Carmy I’m having the same problem but the driver side fan working but the passenger side fan not working , and my gags going up a little like it trying to run hot ,,,what should I do.
I've worked for Toyota dealers since 2004, and a professional mechanic for 32 yrs....this Toyota cooling fan wiring is one of the most WHACK I've ever encountered, but the one Toyota quit using in 1994 was worse...using the power steering fluid to power the fans...such crap.
@@starwart The 94 Camrys had the fan system connected to the power steering pump. They were run by the power steering fluid (not electrical current). It was a ridiculous design.
1:00 can you explain more about that sensor on the bottom of the radiator? I have a wire with a broken connector that goes down that way, but just sits on the floor. The other end is exactly where you had your hand. Where you could see but we couldn't. I replaced my radiator yesterday, but didnt see anything for that. 2:55 my fans are always on *when the car's on.* but not when it's off. EDIT: i think i figured it out. You were a huge help dude! Thx!
Thank you for commenting. Im glad you figured it out. Hope you get lots more miles from your Camry. We also have Prius repairs too. th-cam.com/video/8fshMta375I/w-d-xo.html
I have a 94 Camry I have the exact same problems. But my fans don’t come on when I turn on the AC. I put in both temp sensors (new). I put in 3 new relay switches. Still not workin when it gets hot. Must be the cradle that #1 sits in How can I fix?
Good video. Had to replace passenger side fan. However with AC off, engine at idle, engine overheats and fans stay off until I turn on AC. Then both fans turn on. Any suggestions? It's a 1999 camry 4 cyl.
My 2001 2.2 4cyl camry is doing the same thing. I replaced the radiator, thermostat and coolant temperature sensor. Fans don't come on unless I turn on A/C
I have a 98 Camry where the cooling fan comes on when the key is in the on position even when the engine is cold. I assume thats the coolant temp sensor bad, but Im also missing that orange relay. I got a Duralast part #20382 from Autozone for it but it looks completely different from the one you show. Did they change them from 97-98 or did they just revise the part?
I dont know if they changed in 98 or not Chris. I would go to a junkyard and ask them to let you look at one. Or start eyeballing the used car lots till you see a 98 for sale and peek under the hood. Also I think your right about the temp sensor.
Thanks for the reply. As of right now Im on my way back to Autozone to get a Four Seasons Relay Part number 36126. It should be a direct replacement for that orange relay. Ill update when I get back. If it works Ill let everyone know and hope it helps someone else. Thanks for the info!
2000 camry 2.2 The fans work they turn on when AC on or the lower plug on front top on radiator rear unplugged. What I am trying to determine is how to find if the temperature sensor on lower radiator is faulty thus might be keeping them from automatically turning on.. Right now it seems as though they might not be because the fans do not turn on automatically. Work done to figure this much out is replace thermostat I'm trying to not buy both a temperature sensor and a relay
Hey Saneauto, great video. I have a 99 Camry that overheats when idles and once you start driving, the engine cools down. So i did your test to see if the fans would come on by unplus the temp sensor and they did not. Does this mean that the fans are most likely the problem and need to be replaced? Or should i replace the relays and senors first?
Little late but its possible to see with a voltmeter if there's any electric current coming what plugs into the fan. If there's power, its possible that the fan itself might be bad.
Your issue is the exact same as mine with wiggling the relay. Have you tried to replace the fan switch located on the radiator? That was the problem with mine.
I have a 1996 Toyota Avalon. Fans didn't come on until I pulled a plug off a coolant sensor. Is there a way to determine which relay it is? When the relays are hooked to test leads and a 9 volt battery they click as though they function. Any help to diagnose would be awesome. Thanks. Great video as well.
The power has to go through the relay to get to the fans. If they came on when you unplugged the sensor the relay is working. That also tells you the fan motor works. The 9 volt test you did also makes me think your relays are working. Try changing the sensor you unplugged. The 96 may be different but the 97 I was working on here has 2 sensors the one at the engine amzn.to/2S993hC but I think the the one in the radiator is different.
Ten years ago my 96 Camry was a overheating. the temp gauge went to hot come to find out the fans weren’t spinning and the thermostat was stuck closed. aThe reserve bottle was boiling and overflowing too.The fan relay was bad too. Ten years later it’s doing the same thing. i’m assuming the same issue is happening. The fan isn’t spinning and the gauge is on H. i’ll keep you posted
I'm having an interesting issue where the fans are constantly running the second the key is on. I've checked the relays and they are all good. I replaced the temperature sensor at the bottom of the radiator with a new one, and I replaced the wiring coming directly from it from a junkyard. Still having the issue. I wouldn't care about this normally, but I live up north so it's not ideal having the fans run all the time when it's freezing cold out. It's very frustrating. Any ideas?
I'm dealing with the same thing. In the beginning of the video he points to 2 sensors on the engine water return hose port. I changed the green one toward the trans, and the one on the bottom of the radiator. Maybe the grey one next to the green one?
Which camry did you own ? a 4 cyl or 6 ? There is a second EFI coolant temp sensor (two wire plug) that is very chubby looking. That one might be the cause. I am not going through the same thing and I am going to attempt repairing it.
When I unplug that plug on my 2000 camry even with the ac on my fans won't come on. What could cause that? Other than both my fans being bad. Thank you for any information.
@@saneauto no not yet I do plan on buying some wire when I get out next. I also ordered a relay tester. So I want to track down the problem just haven't yet. But was wondering why the fans didn't come on when I unplugged the wire, but I will have to get some wire and I also order some prope led's to stick in the plug but got to wait till it comes in.
@@saneauto yes I did and neither turned on. I even checked with a multi meter that the jumpers were working and neither fan shows anything so pretty sure I need new fans. Edit I just got two fans from a junk yard works great 👍

Having exact same problem. I also did notice that touching1-2 smaller relays started the cooling fans right up. I’m ordering a relayed sensor tester to check

(My 95 Camry with 5SFE engine will kick the fan on and off when idling for prolonged periods).
I watched your video, with the lower radiator twmperature switch plug disconnected, both the engine cooling and A/C fans operate. All three relays can be felt to be engaging. No change from wiggling, both fans run. Pull #2 relay and engine fan quits. Reconnect lower radiator temp switch, both fans quit. Turn on the A/C system and both fans operate.
I replaced the lower radiator temperature switch with a known good used one and the engine cooling fan still does not operate. Pulled the connector apart again on the top corner of radiator and both fans came on. Jumpered the two female terminals in the harness plug and the fans went back off.
Went to the temperature switch (two terminal, green female connector) mounted next to the temp gauge sender in the upper radiator hose elbow on the driver's side of the engine and disconnected the plug. No change, fans did not run. Jumpered the the female plug, nothing. Both the engine compartment 30A fuse and the dash panel 7.5A fuse for the fans were/are fine.
I'm stumped. Is there a wiring issue to the engine (upper radiator hose elbow) temperature switch? Do I need to replace both the lower radiator and the elbow temperature switches with new OEM switches? I currently have the lower radiator switch harness disconnected to run both fans constantly, as my daughter's daily commute between her apartment and both jobs entails a lot of stop and go driving across town and back and I don't want to run the risk of overheating and toasting her motor.

Thanks man I wish I had filmed even a tiny fraction of the repairs Ive done. Thats how I got started on youtube. Heres my repairs playlist th-cam.com/play/PLADlyv_PN7XJpaCV0OeFG8Frm1240FsET.html
Hello im having the same problem. I changed my thermostat, Relays, fanswitch, tempswitch. The thermostat opens and gets hot so i know the radiator is working. Idk what else could be causing my fan to no turn on.
Zack Saepharn
Did you ever figure this out? I replaced everything but the radiator so far and a couple sensors twice.
Fans are either burned out or the fuse box socket is bad. Go to your junkyard and buy both there.
Did you ever figure it out? Same issue.
@@thegreatgiginthesky387 did you figure it out? I have this issue as well
You just saved me $600. Thank you so much! God bless you.
this will be a big help for me. will check with that and test if its working as demonstrated. tnks bro
Thank you for commenting
Your video has a very similar problem to what I have going on when I turn the blower motor for the AC on the fans run but when I turn it off with the AC the fans turn off and never come back on except without turning on the AC plus the radiator fans don't turn on high
Did you ever fix it we’re having that problem
I have that same problem! How did you repair it?
I think it was the motors it's been a while since I've done that
@@christopherkendrick8279 ,my fans only come on when i turn on the ac knob to hot. If i don't do that the fans don't turn on and the car overheats
Great video! So my question is when my engine gets hot my cooling fans do not turn on. But when I have my ac on both fans work fine. What could be the issue
I have same issue brotha did you figure it out ?
Temperature sensor. They automatically turn on when the AC is switched on.
Thank you. Your video helped me diagnose the problem
Glad it helped. Thank you for commenting.
What fixed this issue ? My. Car is doing the same exact thing
It’s always a relay. I’m diggin that drivers very seat cushion. Knowledge is king! 👍🏻
Nice video...
I swapped the engine on a 2.2 lt that was running good.
But now the engine that was swapped is overheating...but I noticed that my fans ain't coming on...I'm gonna try this tomorrow thanks!!!!!
Exactamente mi problema.
Mañana arreglo mi carro.
Ojala sólo sea problema del relay.
Gracias por la info.
I love this video can u make a video were u can break it down for me on how to diagnose the fan I'm having the same problem
I'm having same problem, wished you would've fixed problem. Was it main relay, the green one? I'm not even getting power to #1 relay
Thank you. I unplug the cable you guy’s showed me and fans on. Made it home thank you.
My fan come on when I turn on the air machine hey want come on with air off.why I set a while start running hood.I replaced the number 1a I’d three relay.I’m having a heck of a problem.your video was really helpful.
When I unplug that cable the fans do not turn on even when the AC is on. The fans don’t turn on when the engine is up to temperature. I checked the resistance of the engine coolant temp sensor on the bottom of the radiator and its reading 7 ohms. I know when its a cold, the engine should be reading 5-6k ohms. I tried bridging the connection of the disconnected wire to bypass the sensor to verify everything else worked and it still did not work. I replaced all the relays and checked the fuses inside and didn’t see any issues. I connected each fan to the battery and they both worked so I am stumped on what else it could be.
This is really informative, thank you
Can anyone help me though, I have the opposite problem of this video! My fans are running all the time even with the car off in the key out!
Have you tried pulling the fan relay out?
@@saneautohi
i have not yet
I actually thought that was probably going to be eight implant to get one tomorrow, or check it
However, I then remembered that my right tire went over a curb and something scraped a little right before I noticed the fans staying on all the time when I turn the car off!
So, I'm thinking it's probably the sensor on bottom passenger side of radiator
What is the part name of the sensor in the bottom of the radiator? I think I need one of those but can't figure out the name of it.
Hi there, Inhave a 2000 Toyota Sienna. The fans only come on when the heater is turned on, when the car is left to idle the fans never kick on. This causes the coolant expansion tank to keep filling until it over flows spilling out as the liquid expands from the engine heat.. There are no codes or check engine light. There are three fan relays back to back just like yours with a brown one in the middle. However the fuse cover doesn't indicate a "Main" fan relay like the large green relay on your camry. There is a large black one that just says Main.
This video helped, but not with my similar problem.
The fans wirk when the AC is on, but not when the car gets hot to cool the radiatoe. I tried a new relay for fan #1, but it didn't work. The dan kicked on for less than a minute after trying the new relay but went off again. (The heat doesn't work, (the inside fans blow), but did when the fan went on)
Same problem I had try changing the green plug sensor on the water neck
Thanks man helped a lot. I’m surprised about unplugging the sensor so it will stay on
I have a Toyota Camry 2000. My radiator fan only goes on when the air condition is on. I troubleshoot the relays and electrical system. A ok. But the fan does not go on if the air condition is off.
mine too.... please post a solution if you ever solve this horrible mystery!!!
Interesting. I've never seen under the hood of one of those. Good info!!!
Very knowledgeable. Thank you so much for info. all was helpfull. I appreciate you. ❤
97 Camry v6. Fans inoperable at all times. Fan motors tested and work independently. Unplugging two wire fan switch at bottom of radiator does nothing. Relays check out fine. Thermostat and water pump fine. What else could be issue. Ecm?
This might be a dumb question but do these fans only come on when you turn the AC on? Or are they always supposed to be on so your car doesn't overheat?
they are supposed to come on and go off when the radiator gets hot, regardless of whether the AC button is lit up green or not.... but my radiator fans only come on and off as intended when i have that AC button pressed and lit up... if the interior dash blower fans are off and the AC button is not lit green-- my radiator fans WONT COME ON.... ugh...
How do you change the socket that the relay for the coolant fan
Did you make another video? My original problem was that the oil pressure light on dash was showing up as on but only after engine got hot, and sat at idle. We hooked up a Harbor Freight oil pressure gauge up to it, but it said good oil pressure. Turns out, my fans we're not turning on whenever the engine got hot, causing oil to run thin, causing less pressure (I think that's how the physics should work????)... I replaced the upper radiator hose, thermostat, radiator fan switch(sensor) below the radiator, and the green engine coolant temperature sensor (2 terminal/green one) next to the block. STILL nothing. Fans will NOT turn on. I just ordered the single terminal OTHER engine coolant temp sensor on Rock Auto to see if that will solve the problem. I will report back. Also, I'm not sure if this has anything to do with it, buy my AC doesn't work, but when I swap relays, it will work for a month or two. Then I have to buy another relay. Any advice appreciated. Thanks.
2003 Chevy trailblazer 4L60E transmission no shift any gear or reverse. Pls help trying to fix for my daughter. Thanx
My number 3 fan relay was not clicking so I swapped it out with the switch from my donor car. That seems to have solved the issue.
Awesome
Nice video! Nice trouble shooting list rundown!
OK I have a 1999 camry. Unplugged the connection on the top back side of radiator and fans still didn't come on. Unplugged fans and straight wired them to the battery and both worked. Any idea what the problem is? Thanks.
Could be a bad fuse. On toyota 1999 the fan fuses are most likely labeled rad and cond. Short for radiator and condenser fan. Checking the fuses may lead to some info.
So if the relays are ok and the fans run fine with the temperature sensor unhooked does that mean the temperature sensor is bad?
Thanks this video was very helpful it saved me some money.
Awesome Im so glad to here that. thank you for letting me know.
Not exactly my issue but I did have that one . Did exactly what u did... It worked. Now I have ac issue. My car guy here in town seems to think it the Head? Controls in car , ac button ? Need advice. Like your down home style. Thanks sane car man. Hot in Hot Springs AR
I hope this Camry Video helps with your A/C issue -- th-cam.com/video/871qKkO6Vjo/w-d-xo.html
I got another relay and had same issue
Same here. Did you end up figuring it out?
Thank You. Greatly appreciate your video.
I love this video very informative! Straight to the point! Have the same issue with fans running all the time so I’m changing the relays first then fuse then temperature sensor but first I drive it for a while to see which one fixes it first will post an update
Awesome keep us posted
Please post which one fixes your problem. I'm having the same problem. My fans stay on.
@@bassflo1 what fixed the problem?
We still waiting
Still waiting
I no this is very basic but it'll definitely keep the parts cannon from coming out in a situation like this. My problem was on a 2003 solara and the fans were not coming on. Turns out the the ECU-IG fuse was taken out. My gf was trying to make the clock work again & was confused on the fuse order in the panel as it relates to the diagram. So b4 u do any thing verify power by ensuring all fuses r n place etc
I have the same car and year, same set up. my problem is fans do come on with aircon, but I'm worried the heat sensors you point to on the pipe are not working. Is there a way I can test with engine cool? I(ts summer here in New Zealand and it get mighty hot. Your video is so good and and you explain things well. Thanks you, Marc
Did you ever figure out the answer to your problem? I'm have the same issue.
@@jacobfrench3961 I replaced all the sensors 3 I think, then I replaced the radiator cap. It all seems to work now
Amazing.. Is it fan motor connect with dasboard meter? My dashboar awlays on and off repeated while driving, if meter going down, my meter running down oso...
I need to know bout it I was by a mechanic need sensors for the fans but the fans are working
I have a problem of the fan does not working when start the car how can i fix it?
I have a problem with my 1999 the fan doesn't come on and I tried what your video showed what else can I do
By any chance do you know what the sensor (grey)next to the coolant temp sensor(green) is called?
My fans are *always* on. Main thermometer works fine.
Can you do a thing on that?
I'm having the same problem. Did you figure it out?
both fans run with sensor disconnected can hear all relays clicking but wiggling relay does not start fans.. wahts the next test to diagnose problem if I am interpreting this as not the fans not the relays ?
first thing checked was fuse and it was good
Thank you so much for this video
My sons 2001 camry has this problem..fans working but only when heat is turned on...must be a fuse..right? Already replaced both temperature sensors on top of engine.
fan sensor # 1 where is it located
2005 Buick Century cooling fans not working. I hot wired the fans, both worked. Replaced 1, 15 Amp. fuse. Replaced relays fan 1& fans. What next, check for broken wires. What about the coolant temp. sensor? 10:03 10:03
Yea, make one more in depth on this problem. I did that test and both fans came on, then went to the relays and the fan2 did have an issue but I didn't get fan3 to do anything so not sure what else to look at other than replace all three relays.
How did you fix the issue
@@ProvacativeAcorn I replaced that relay on fan2 and also replaced the temp sensor at the thermostat. It's usually the temp sensor that goes bad. So start with the relays but it doesn't hurt to replace the temp sensor as well.
@@jamesplummer9043 there’s a temp sensor on the thermostat? You mean the temp sensor on the radiator?
@@ProvacativeAcorn yes, if you follow the top hose connecting from the radiator to the thermostat there a temp sensor. It's a 19mm wrenchto remove it.
@@jamesplummer9043 are we talking about the same car? My 1997 Camry has the thermostat in the lower radiator hose not the upper
Hey Sane. My passenger fan wont come on after I pulled fan 3 relay out. It was very hard to pull out and plug back in. It was running when I pulled it out
Both fans are out i think its main relay switch fan #1 I can hear #2 switch but not #1. Could there be another problem that would cause both fans not to turn on.
I got the same problem, I change ,thermostat, water pump, timing belt all rellays, all sensor all fuses and fan still don't come on what else I can do thanks
Every figure it out?
My 01 Camry has both fans on all the time,whatever cause it,what do you think it is ?
I'm having the same issue. Did you figure it out?
@@jeffp6244 not yet,too cold out to work
God bless you thank you
Hey I have this problem but the fuses are good .. and thermostat and coolant sensor is fine no codes are reading ... Had a engine gasket replacement
Got a 96 Camry the car is doing the same thing as your car is doing in this video is there any more testing that you can do to get the fans to work we wiggled the relays that seems to be fine I feel the clicking on the 3 relays so we are in need to get this fixed or do you have any more videos on this thank you for your time and help
So I have a check engine light says temp sensor I've changed all 3 sensors my fan doesn't seem to come on at all car stays same temp about medium heat lmk if you can help thanks
So, did you replace the relay on the fan that didn't come on? Cause my 92 camry only turns on one fan when hot(the same u spun with the orange relay) but the other doest not come on, only with the ac switch and just then both come on
Man I’m soooo grateful for this video!
Yes hi. My problem is in my 2000 Toyota solara my fans constantly run not when the key is off but when you just turn the key on the fan to run so the car always takes a long long time to warm up so I was just wondering what you might think that could be as well I'm sure it's on the same line as maybe the relays maybe I don't know but the fans always run constantly. If you have an idea please let me know thank you
Hello I have a 2001 Toyota Carmy I’m having the same problem but the driver side fan working but the passenger side fan not working , and my gags going up a little like it trying to run hot ,,,what should I do.
I've worked for Toyota dealers since 2004, and a professional mechanic for 32 yrs....this Toyota cooling fan wiring is one of the most WHACK I've ever encountered, but the one Toyota quit using in 1994 was worse...using the power steering fluid to power the fans...such crap.
wait... what do you mean?
@@starwart The 94 Camrys had the fan system connected to the power steering pump. They were run by the power steering fluid (not electrical current). It was a ridiculous design.
1:00 can you explain more about that sensor on the bottom of the radiator?
I have a wire with a broken connector that goes down that way, but just sits on the floor. The other end is exactly where you had your hand. Where you could see but we couldn't.
I replaced my radiator yesterday, but didnt see anything for that.
2:55 my fans are always on *when the car's on.* but not when it's off.
EDIT: i think i figured it out. You were a huge help dude! Thx!
Thank you for commenting. Im glad you figured it out. Hope you get lots more miles from your Camry. We also have Prius repairs too. th-cam.com/video/8fshMta375I/w-d-xo.html
I have a 94 Camry I have the exact same problems. But my fans don’t come on when I turn on the AC. I put in both temp sensors (new). I put in 3 new relay switches. Still not workin when it gets hot. Must be the cradle that #1 sits in How can I fix?
Good video. Had to replace passenger side fan. However with AC off, engine at idle, engine overheats and fans stay off until I turn on AC. Then both fans turn on. Any suggestions? It's a 1999 camry 4 cyl.
My 2001 2.2 4cyl camry is doing the same thing. I replaced the radiator, thermostat and coolant temperature sensor. Fans don't come on unless I turn on A/C
@@AnyMeansFreightSolutionsdid u guys find what fix the problem I have the same issue ?
Nice video !!
My fans stay on when the car is running with A/C off
Check coolant temp sensor at the bottom of radiator. It may be have circuit stuck closed.
I have a 98 Camry where the cooling fan comes on when the key is in the on position even when the engine is cold. I assume thats the coolant temp sensor bad, but Im also missing that orange relay. I got a Duralast part #20382 from Autozone for it but it looks completely different from the one you show. Did they change them from 97-98 or did they just revise the part?
I dont know if they changed in 98 or not Chris. I would go to a junkyard and ask them to let you look at one. Or start eyeballing the used car lots till you see a 98 for sale and peek under the hood. Also I think your right about the temp sensor.
Thanks for the reply. As of right now Im on my way back to Autozone to get a Four Seasons Relay Part number 36126. It should be a direct replacement for that orange relay. Ill update when I get back. If it works Ill let everyone know and hope it helps someone else. Thanks for the info!
Sounds like a great plan.
Four Seasons part number 36126 worked. AC fan comes on now. Appreciate this video it helped me track down the problem.
Thats awesome. Thanks for sharing your fix and part #s. Hopefully I can build a website soon that will let us share photos and more.
2000 camry 2.2 The fans work they turn on when AC on or the lower plug on front top on radiator rear unplugged. What I am trying to determine is how to find if the temperature sensor on lower radiator is faulty thus might be keeping them from automatically turning on.. Right now it seems as though they might not be because the fans do not turn on automatically. Work done to figure this much out is replace thermostat I'm trying to not buy both a temperature sensor and a relay
Hey Saneauto, great video. I have a 99 Camry that overheats when idles and once you start driving, the engine cools down. So i did your test to see if the fans would come on by unplus the temp sensor and they did not. Does this mean that the fans are most likely the problem and need to be replaced? Or should i replace the relays and senors first?
Hey did you ever figure it out . I’m experiencing the same issue
Little late but its possible to see with a voltmeter if there's any electric current coming what plugs into the fan. If there's power, its possible that the fan itself might be bad.
Your issue is the exact same as mine with wiggling the relay. Have you tried to replace the fan switch located on the radiator? That was the problem with mine.
Wait so both your relay was bad and the fan switch was bad?
I have a 1996 Toyota Avalon. Fans didn't come on until I pulled a plug off a coolant sensor. Is there a way to determine which relay it is? When the relays are hooked to test leads and a 9 volt battery they click as though they function. Any help to diagnose would be awesome. Thanks. Great video as well.
The power has to go through the relay to get to the fans. If they came on when you unplugged the sensor the relay is working. That also tells you the fan motor works. The 9 volt test you did also makes me think your relays are working. Try changing the sensor you unplugged. The 96 may be different but the 97 I was working on here has 2 sensors the one at the engine amzn.to/2S993hC but I think the the one in the radiator is different.
Ten years ago my 96 Camry was a overheating. the temp gauge went to hot come to find out the fans weren’t spinning and the thermostat was stuck closed. aThe reserve bottle was boiling and overflowing too.The fan relay was bad too. Ten years later it’s doing the same thing. i’m assuming the same issue is happening. The fan isn’t spinning and the gauge is on H. i’ll keep you posted
Thank you for commenting. Looking forward to your update. Your also welcome to join our Sane Auto facebook page and share there as well.
I replaced the fan and all fuses and one fan doesn’t turn on like for nothing even when I unplug the temp gage any suggestions?
Try using some jumper wires to put power to the fan not working. Even if its new it could be bad.
I'm having an interesting issue where the fans are constantly running the second the key is on. I've checked the relays and they are all good. I replaced the temperature sensor at the bottom of the radiator with a new one, and I replaced the wiring coming directly from it from a junkyard. Still having the issue. I wouldn't care about this normally, but I live up north so it's not ideal having the fans run all the time when it's freezing cold out. It's very frustrating. Any ideas?
I'm dealing with the same thing. In the beginning of the video he points to 2 sensors on the engine water return hose port. I changed the green one toward the trans, and the one on the bottom of the radiator. Maybe the grey one next to the green one?
Which camry did you own ? a 4 cyl or 6 ? There is a second EFI coolant temp sensor (two wire plug) that is very chubby looking. That one might be the cause. I am not going through the same thing and I am going to attempt repairing it.
When I unplug that plug on my 2000 camry even with the ac on my fans won't come on. What could cause that? Other than both my fans being bad. Thank you for any information.
Have you tried disconnecting at each individual fan and using a jumper wire to test them?
@@saneauto no not yet I do plan on buying some wire when I get out next. I also ordered a relay tester. So I want to track down the problem just haven't yet. But was wondering why the fans didn't come on when I unplugged the wire, but I will have to get some wire and I also order some prope led's to stick in the plug but got to wait till it comes in.
@@saneauto yes I did and neither turned on. I even checked with a multi meter that the jumpers were working and neither fan shows anything so pretty sure I need new fans.
Edit
I just got two fans from a junk yard works great 👍
My relay socket seems to be bad ..when I jiggle the fuse fans come on.. do I use a continuity tester to see if socket it ok
