i think my cooling fan may be bad, i was sitting idle with the A/C on and i noticed the temperature gauge was getting high but as soon as i turned the A/C off the gauge went back to normal… it was also normal when i was driving and it sounds like i can hear the fan when i’m in a drive thru… it’s also hot af in texas right now
@@ElmerPacheco-j9j mine wasn’t too bad and did solve all my problems, part was 184$ and they charged 150$ for labor. Ngl the labor seemed excessive since they did it in 45 minutes. I think I probably could have done it myself but was afraid of messing something up. If only I had confidence
I had this problem last year in September. I was driving at highway speeds and the AC was cold but in the city it wasn't as cold. It also overheated and stop and go traffic but when I was on the highway it didn't overheat. So yeah it was the fan and I fixed it but I already knew that before watching this video but it's still very entertaining So thanks.
I have a problem with my Mercedes e300, fan sounds like a jet engine but I took it to my mechanic and they said nothing in the car is telling the fan to turn on, so they said I might need a new battery will cost me about $500-$600 plus the labor.
Think I found my issue. My cars AC gets iced cold at higher speeds and semi cold at lower speeds. The cooling fans don't work at all not even when the ac is on. However, I tap the fan motor and it turns on. And I wanted to say it was a bad thermostat or bad ECT sensor and the relays and fuses but I replaced everything. Fan still don't work. The engines temperature stays at 195° when I'm driving the car. But at a stop light or stop sign for too long and it'll overheat.
I have the exact same issue except my fans do come on but then immediately turn off every other minute making the car overheat. Not sure if u should just replace the whole radiator fan or if it may be another issue.
If anyone sees this, I replaced a 40amp L shape fuse on my g35 coupe and it turned the radiator fan back on (passenger fan). Then it stopped working a few days later and I saw the fuse bubble up and it’s not blown but it’s to the point where it won’t spin so I guess it’s blown. The fan is aftermarket OE fan so could it be drawing or trying to put out more amps then the 40amp fuse can handle thus causing it to blow? If so I’ll replace the fan Motor
What if the fan runs but your temperature rises when it's idling or low speeds? Fan runs constantly, even when you've cut the engine. Water pump and radiator are fine. Could it still be the fan?
What is the cause of a fan running loud. There are not check engine or other temperature sensors on. Is the motor bad or do I need to replace the whole fan assembly?
I have an 01 civic and turns out my fuse in my car has a bigger amperage than the original cooling fan fuse.Everytime I turn on my car the fans kick on immediately I'm ordering a new fuse rn.
What is a bad radiator? Its either working or not? Or its not spinning fast enough, which makes no sense as the car is still not overheating just not cold ac.
so my ac randomly breaks.. I drive the car without ac for 2 days or so before I noticed the car was heating more the usual, and then all of a sudden I notice my engine fans weren’t turning on
Can a malfunctioning fan be intermittent? My car's temperature light came on, car was overheating when idle with the AC on, and days later without the AC on. Can't seem to replicate it again though 🤔
@@cenchloraadums3143 you're not wrong. Unfortunately the fan motor gave out about 2 days after posting my comment. But I was able to replace it and now thankfully everything seems to be working great!
2005 police crown vic ---- BRO I NEED HELP! been having overheating issues & replaced everything in the system. NOT overheating anymore but the radiator fan goes to high after only 5 mins of running. stays on high fan until shut off. replaced the radiator, water pump, CT sensor, HT sensor, thermostat (160), fresh coolant after 3 flushes. used a laser temp tool & highest reading on cyl or anywhere, is only 160 degrees. fan will be on HIGH with that LOW temp. CANT FIGURE IT OUT & NEED TO SELL!. NO ENGINE CODES.
I am having these issues. Turns out both of my radiator fans are not working. I didn't notice the AC fan went out since the main still worked until a few days ago. Not sure when the first one went out, but I guess it is common since the main fan can easily compensate. When I tried to take off the harness from the secondary fan, the harness plug mated to the fan crumbled off and was burnt. I decided not to mess with the main fan plug on the off chance it might still work, it doesn't even after bypassing the wiring. I ordered a temporary universal fan via 2-day shipping until I figure things out.
Mine is making loud noises when Ac is on and when its not. And alternator and battery light popping on and off, seldom. I just had Nissan replace alternator, so I know its not that. Their now saying its the radiator fan wobbling. But it wasn't doing it prior to alternator fix. This is so annoying. 2013 jx35
My 2011 ford taurus had the water pump replaced because of leak. But car over heats with running a/c and the fan doesn't shut off and it drains the battery. Please help Thank you
my radiator fan doesn't run, and my ac acts exactly haw you described but everyone I asked says they're not related but none of them have looked at it can you tell me other reasons why both wouldn't work?
If one of the two fans is working, should the other be working, also, at the same speed? Or is it computer controlled and additive, meaning does only one fan sometimes come on, normally, and the second fan only when needed? I've got one of the two fans that is acting sluggish when I first started the car, then stopped completely before the motor warmed up - not sure if this is normal or not. Thanks!
Every part of my cooling system works and every component of the ac works.but my radiator fan stopped working and apparently thats why my ac isnt working
I live in Az..its hot.. When I 4x4 I see that my truck kinda starts over heating when I really rush my truck... like climbing up hiills.. SO maybe i should rig up another fan in front of the condenser? would that interfere with the air flow? also cause more cooling with my ac?
I’m having an issue where as though my fan keeps running after I turn the car off and it drains my battery, I just changed the fan and it’s still doing the same thing, what do I do?
Many of reasons. Could be lost of proper voltage/ground. Is the low and high speed not working or both all together ? If you have proper voltage and a strong ground to your connector. You should try take the fan off and jump the power and ground to the pins. (Note) don’t worry which pin is negative and positive. It’s a dc motor so you won’t hurt anything if you’re worried about crossing the wires. Fan will just spin backwards if anything. But try to supply external power and ground to the control module and if that don’t work. Your narrowed down to a bad control module or motor. You can also by pass the module and juice directly to the motor. If your fan starts spinning after juicing directly to the motor. Your culprit is the control module. Hope this helped. And goodluck with your problems!
@@mupcountry7153 same here, will replacing the whole radiator fan fix this issue? Or is it something else. I don’t want to buy and install a fan without it being the actual cause.
Thats normal it turns on and off to regulate temp not to keep running. The problem is when yoy turn ac on and fans don't come on at all when idle or at a stop light which will make the car start to overheat.

@@papajoewil10 yeah it turns out one of the fans weren't working so i replaced it and it's working perfectly again
@@sweet49101 Thanks for replying having this same issue right now
Facts. Im in Houston and shit been 100 degrees
My car fan makes very horrible sound if I drive my car more than 15 minutes or I stuck in traffic for long , and alot of water leak down
great video but something about the way this guy talks was just making me wonder if he's real?
Mine started to smell like burnt rubber, and it's on all the time, toyota tundra.
Should I replace it?

Check PCM module connectors for corrosion and use alcohol to clean them
Had that issue. Replace my ac compressor solenoid valve
@@rosendaniel1258 that affected the fans ?

If anyone sees this, I replaced a 40amp L shape fuse on my g35 coupe and it turned the radiator fan back on (passenger fan).

Did you find out?
Fan speed controller. Or a stuck closed relay. Should check both to eliminate the problem
What is the cause of a fan running loud. There are not check engine or other temperature sensors on. Is the motor bad or do I need to replace the whole fan assembly?
Your motor is bad lol
Jk
High/low control module
Or could be the temp sensor that’s relaying false information and causing the fan to run at high speeds when it really shouldn’t need too much
I have an 01 civic and turns out my fuse in my car has a bigger amperage than the original cooling fan fuse.Everytime I turn on my car the fans kick on immediately I'm ordering a new fuse rn.
Noticed my second fan doesn’t turn on when it hits 200 degrees

STOP CUSSING.
@@dreamerhall8920 fuck no 😂 grow up the word “damn” isn’t a cuss word
How would I deal with a radiator (cooling fan) pulling to much power to where the car rpm idles up and down and stalls the car
so my ac randomly breaks.. I drive the car without ac for 2 days or so before I noticed the car was heating more the usual, and then all of a sudden I notice my engine fans weren’t turning on
I’m having this same problem as well
Thank you u made me feel more relaxed every other video was freaking me out
Good to hear!
You freaked yourself out ,not the videos, sadly we all have too hear the truth and that's not very comfortable

Looks like you've got a faulty cooling fan. Try replacing the fan motor before it eventually stops working completely.
@@cenchloraadums3143 you're not wrong. Unfortunately the fan motor gave out about 2 days after posting my comment. But I was able to replace it and now thankfully everything seems to be working great!
What if it's always on even on a cold morning or weather ? And no engine light on
Possible that your air conditioning pressure sensor is malfunctioning.
Thermostat

I have Five Hendard, the car suddenly overheats, the air conditioner becomes hot and the fan is not working, what's the reason?
Can the fan still be bad if it still gets power from the battery
Does the ac compressor have to be running for the fans to activate.??

Will this cause the air flow to be weak coming from the vents also?
No

Stuck closed relay?
This guy is Chris fix it.
liked and subbed man these videos are gold.
I appreciate you!
I just ordered new fans and shroud.
I replaced relays already didn't fix it.
Remember if yoy order new fans also get a new coolant temp sensor as well
Coolant temp sensor ?? You mean the thermostat???
Mine keep running all times, is this bed
Yeah probably bad thermostat
👍
What if your cooling fan won’t stop when the cars off causing the battery to die?
Mine was doing that and i replaced the relay fuse
yes
My cooling fan turns on and off while my AC is running . Do you know what the problem can be ?
