Hell one of the mechanics I worked with had one of those big ole metal radiator fan catch his finger and all it did was knock off some crud.
@@stobbinsboy - Lucky escape!
I thought the exact same thing when I saw him stick his finger in there
I think he knows what he’s doing

My 93 corvette was programed from the factory to only turn on one fan on when the ac was on.
Makes sense if that one fan covers the complete condensor
@@OnlineMechanicTips it did not. But recently I modded the car and now both come on with the ac. I live in southern Arizona so it was a much needed improvement.
That's why in the older days before electric fans in the car when we did air conditioner Servicing we checked the temperature coming out of the ducts before and after putting a fan in front of the car imitating 40 miles per hour which at that time was the optimal speed of Maximum efficiency of the AC
Man I'm gonna start being a career mechanic soon this video is gonna help me, especially that Lil tip about checking the connector for power to quickly diagnose the issue, I almost feel embarrassed not knowing that already lol.
th-cam.com/users/shortsFbIUXiOHdU8
Always check for power on an electrical part.
both fans dont have to be running for it to be operating normally. the other fan is more for engine high temperature cooling, not for air conditioning.
I love these videos, keep up the great work brotha 💪👏🙌🙏💯
More to come!
This is where a power probe is worth its weight in gold.
Don’t ever put your fingers in a radiator fan, ESPECIALLY when the vehicles is on or running. Assume it can kick on at all times.
True, but I'm extra careful. I know how far to go, thank you
The good thing is that it was the middle finger you really don’t need that finger other than to flip people off 😂
If the motor was "stuck" or the brushes have a ton of carbon, simply moving the fan can make the motor make a connection and start working.
My dads car has the same problem and it overheats at idle. I just checked and only the small fan is running. Thank you! Learn from you every day!
Thanks for watching
Lesson learned not to stick your fingers in a fan? Hes a lucky guy it didnt kick on. Not all fans come on at the same time
Thanks for the advice, honda civic just started doing this and the crv also just stopped blowing cold at all times. Will check both 😊
So what did you have to do to get it to work again because one side works on mine and then the other one doesn’t
To the point and plenty of description. Ya rock bub.
Thanks for watching. th-cam.com/users/shortsFbIUXiOHdU8
I’m dealing with a similar situation but with a mechanical fan. I found at an idle every time you give it gas the compressor kicks on and when you let off the compressor shuts off
I had the same problem yesterday with a 2011 Hyundai Sonata where the low side pressure was at 85psi at idle and high side at 150psi. When I Rev the engine to 2000rpm, the low side pressure pulls down to around 60psi. My result is a weak Compressor. Condenser fan (which is just one fan) spins just fine.
A very simple formula for ac:
^T=^t X cfm
Where^ means change (delta)
T means temperature, and cfm means cubic feet per minute
th-cam.com/users/shortsFbIUXiOHdU8
only time my second fan comes on is when the thermostat opens😂
High side will be high if there’s an air flow or condenser efficiency problem
Yes, pretty much.
Or a fan control module, if equipped with one. I see a worm drive on a brand new radiator hose
th-cam.com/users/shortsFbIUXiOHdU8
to the point. Perfect.
I had that problem once in one of my old Lexus, when the car was sitting still the A/C and heat wouldn't blow cold and hot but it was a different problem. I noticed the rpms were running low also so I took off the throttle body and cleaned it and everything started working fine again at idle.
Both of my fans are running and STILL have that problem. 2010 civic
Do you have a clutch on your ac compressor? If not that's your problem lol won't even hold a charge
@@MacMadeSeedsAndStems
Yes. Clutch engages. New compressor, condenser and valve. I'm stumped
Hard working hands
On my older car, one fan operates with the radiator thermostat, and the other with the ac... I'm guessing it's only newer cars with these one piece shrouds?
Exactly
I had the exact same problem a few months ago. $800 for both radiator/condenser fans.

My 170k mile 2009 Ford Fusion only has one cooling fan, and it comes on when the ac is turned, but the ac is not cooling at idle and barely does while driving 55mph on a 95 degree day. It has a new condenser (the old one had a pinhole leak in it), and I replaced the compressor at the same time and had a shop put the right refrigerant charge in it. It also has a new TXV. Any ideas? Could the cooling fan not be turning fast enough due to a bad control module (that I think has multiple resistors on it for the various speeds called for, depending on engine cooling and ac cooling needs?)
Hey bro love your content especially when a brother man got knowledge like you do because some of my own people don't think we smart enough to do this here's proof right here you the man keep doing it put it out there

If you are not Black and think that you're a jackwagon and if you're Black and think that you've been beat down, hey?
Had this exact problem in my 06 town and country. This looks like the same body style
Vibration tends to break the magnets loose inside the electric motors which stops the fan from working. It is possible to open the fan motor and epoxy the magnets back into place.
man fuck that replace the fan lol

@@RandomLuckk facts 😂😂😂
🥺 I just replaced the coolant temperature sensor and the connector and my ac still not blowing cold and fans still not working. Why's it? Maybe the fans or relays? Please help 😢 I have a 2015 Chevy traverse. It was cooling fine and it stopped working when i was driving.
How much for a mechanic to fix this. My air is not cold once it's very hot out
Your car have to be diagnosed first. No one can give an estimate on something until he knows whats wrong with it.
Besides ramming air driving . What if have to push the idle up with the peddle and either the overheating stops or the air gets cold doing that. . Is it compensating for weak compressor or weak radiator . And turns the water pump harder. And or compressor
Will a relay replacement do the fix? I have corolla doing same thing but 1 big fan. Not running while I'm idle or park
I’m having this problem with my 02 tundra but I replaced the relay and the whole fan assembly and it’s still doing the same thing
Both fans working and full of refrigerant and still not very cold as use to be. Any idea why ?
I had the same problem with my wife's town and country limited
Dang, I hope yall got it fixed
Some cars one is the AC and one is the cooling fan though they aren’t always both on
The Video is about this car/van and thats the case on this one..When I do the trucks I explain this set up that way.
Some cars aren’t programmed to have both fans on when these is on one is programmed for when the engine is to hot and one is for the ac
What if you have the same problem but you just have one big fan and its spinning? Assuming its not the condenser. Could it he a high speed low speed relay?
And the compressor is turning at a faster speed
Thanks
Huge help HUGE
one condenser fan is not functioning, need to replace that defective fan
They dont sell it like that my friend. th-cam.com/users/shortsFbIUXiOHdU8
Looks like we almost have the same van, but my fan is separate, and not one whole unit. But mines doing the same thing and both fans are on, and the freon level and pressure is fine
Clean the condenser and radiator while ya at it.
whattya mean?
The name goes on before the quality goes in 😀
th-cam.com/users/shortsFbIUXiOHdU8
What about on a 2004 Saturn Ion 2? Im thinking it's the fan itself and it's pulling power from my battery because of it being bad. I mostly use fresh air when running the ac instead of recycled but still it's only cold when I'm running interstate speed. How would I test on my 2004 Saturn Ion please and thank you
Mine is the same right now is that why mi AC is not cold??
Thanks for the info. You sound like one of the Hodge twins 😂
Love them dudes. "Do what eva the F, you wanna do"
Just push the plug towards to fan. If the fan starts to run, it's burned out. Just push the connector towards the fan. I bet it starts working.
That's how you can check power.
The motor was burn out. th-cam.com/users/shortsFbIUXiOHdU8
one fan is for condenser cooling and the other is for engine cooling. both do not always have to be on for the system to be operating properly. makes me second guess your abilities as a mechanic. also pressures being normal doesn't mean the system is full.
Theres no need to second guess my ability to do anything dude. Every thing I say on my channel merely my opinion. You also entitled to your opinion. In some cases opinions clash. Such as this one. The setup you speaking about do not apply to this vehicle. The condensor on this car in fact wide and require both fans to work for it to operate properly. So yes, both fans have to operate on this car for max cooling to occur. Also nobody said the sys was full. Before you go trying to correct somebody, maybe you should know what kind of vehicle being discuss in the video. Not all cars the same.
I think the High and low would be on the High side especially the high side. ……..I am a Big Fan Also (:
Thanks my friend. th-cam.com/users/shortsFbIUXiOHdU8
That same fan is not working for my 2005 Honda odyssey. Is that the radiator fan or the condenser fan not working?
My problem!!! Change everything but still not cold AC not working when car was stop
Those fans run whenever the engine temp reaches what the fan thermostat is set at....whether you're moving or not.
What if the AC is not cold at speeds above 60 mph but gets cold when you slow down to 50 mph and less?
What if the fan is good and it has power and ground going to it. Then what??
A typical electric motor such as a fan motor that require a power source and a ground and have both but that electric motor still not operating? Simply mean the motor internally open.
They both work if the a/c is on max.
They both should work
Why would my a/c blow cold at low blower fan speed but not on high?
Temporary Solution, Get the fan wires of one fan and splice them with other for a temp fix till you get another fan.
But the motor burn out. It would not have mattered. th-cam.com/users/shortsFbIUXiOHdU8

th-cam.com/users/shortsFbIUXiOHdU8
Yup thats what happened to my car 🙂
Thanks for the info! I've had this problem with my 2008 Honda Civic for quite some time now. Haven't looked at the fans yet but I will update this comment if you solved my issue!
Just checked my fans and sure enough one of them wasn't working!
Did you get it fixed ? What was the issue
@@Amahyze777 It was a bad fan. I had changed out my condenser and evaporator before I had even realized that one of the fans wasn't working properly. I changed the fan and presto, ice cold air. Would explain why my A/C worked okay on the highway but not residential
What about relays or coolant temp sensor?
Is the car hot enough for the high fan to kick in? Also, ac is gonna be colder when revs are higher, like at highway speeds
This fan assembly run both fans as needed. Both should be running when either on high speed or low speed
My fan was unplug mine would only get cold at high speed now it’s hot again and Dan is hooked up
Hope the customer understands they have to buy the whole assembly
man I just got a 2002 mustang gt and it only blew hot air no matter the setting it was on so I recharged the ac and it still didn't work. so I looked around the car and there's a compressor bypass pully where the compressor is supposed to be! everything else is there so I just need the compressor lmao
One thing they made easy to change on those Malibu’s, had to do spark plugs-wires and a thermostat on my grandmas last winter.. what a pain!
Dude sounds like the HODGE TWINS😂
So that would mean your statement is wrong (pressure will not be normal if it isn't cooling proper at idle if one fan isn't working)
Perhaps, but in this case the high side may rise slightly because only half of it doing its thing. The fan is not even design to come on on some cars until the high side reach a certain pressure (Cars with AC transducer) So depending on when you check the pressure using gauges will it be considered accurate.
I still don’t understand how the radiator cooling fan can impact the completely separate system of the ac.
Pretty risky with those fingertips
lol, yea I was careful. th-cam.com/users/shortsFbIUXiOHdU8
Brave checking the fan with your fingers. Maybe you have extra ones laying around?
Lol, naw, that is def something you should not do.
What about the fuse
You didnt see a real hi high side pressure ? and a little bit hi low side ? Thats our first clue about no fan, or not enough fan. We often get them where the fan is running, but too slow (fan old and tired). Also, where we are from, we have to add anther condensor fan in front, run off a relay from the clutch. (115 degrees in the summer) Makes the AC way cooler, keeps your high side prssures way down
Ok so I need your help! My car was overheating but we figured out that the little square plug in piece on the drivers side closest to the battery/headlights had a short. So we taped it to work all the time and I have to unplug it when the car is off for longer than like 5-10 mins. However, the reason we did not do a toggle switch is because someone said it would affect my A.C. That’s why we are using this method until I can get someone to tell me which of the (3?) sensors is messed up. Anyway, the car tried to overheat the other day so we had to re-tape it a little tighter but now my a.c. Is out completely. It blows but it’s hot air pretty much. Do you think it has something to do with this issue or does it just need some Freon (or whatever it’s called lol)?
I’m gonna go check right now and see about the fans but I have a 2011 Hyundai Sonata. I think there’s only 1 fan but I’m not sure lol 😂
Also it worked great with the taping of the piece until the other day. I think because we have taken it out so many times maybe we moved the tape but it was only a temporary fix anyway. One more thing: I have the new piece but the fan isn’t coming on because of one of the (3?) sensors isn’t telling it to come on. That’s why the piece I am talking about is taped in the first place. It keeps the fan on all the time. That’s why we have to take it out
What about a 02 tahoe doing something clutch fan?
Cooling fan resistor. I’ve replaced dozens of them.
Only one side of the fan assembly was blowing my friend. The resistor you speak of likely supply voltage to both fan. This problem was simply one fan motor burn out.

How we fix the fans ?
how cold should 1234yf get ??? please
Quick question does the fan only run when idle ? I have a chrysler 300 and man fan doesnt run when ifle
Literally helping my boy fix his 300 A/C right now. When you’re at idle the fans don’t spin because they activate when temps get high and the car gets an alert like “hey !! Cool me down cause I’m starting to get hot”. So no, they ain’t supposed to run. HOWEVER, if they don’t cut on when you turn the AC then you have a problem pa
Not all electric fan setups run both fans at the same time. It’s normal for one fan to constant run and the other kick off and on with a signal from a coolant temp sensor. Now if that second fan isn’t kicking on and off when commanded by the pcm then you have a fan issue. Most the time it’s a filthy condenser bc people never think to clean them. It’s even worse and more common in places that are drier climate with more dust. Always try a condenser clean before replacing fans.
You have great points. But on this set up, yes, both fans should be on at the same time. If one is not and the power/ground at the connector then its simply the fan. th-cam.com/users/shortsFbIUXiOHdU8
I doubt thats the Problem lmfao😂😂😂😂
You dought wrong guy. Why do you even dought things that you dont chack? Thats very immature
How are pressures normal if fan was not operating? Head pressure would be elevated due to heat not being rejected from condenser.
Normal as in the amout. Based off those pressure reading, one can assume the sys not empty. Meaning that the reason for AC not cooling is not because the AC sys empty. And for the record, on some cars, the fan not even needed until high side pressure reach a certain amount. So the AC may be cold when first started.
@@OnlineMechanicTips that's on all cars to maintain head pressure during low ambients. There will be either a fan pressure switch or the pcm is programmed to energize fans when head pressure reaches predetermined amount
@@topher8634 To say something apply to ALL cars without even knowing how ALL cars set up simply a risky thing to suspect. Your opinion on the matter simply not true.
@@OnlineMechanicTips that's how ac and refrig works. If fan ran all the time during low ambients, head pressure would drop too low and system would start to ice up. Also expansion devices do not work well below 90 degrees condensing temp. That's why the fans cycle during low loads/ambients. It's not an opinion, it's physics.
Dude you all over the place. In this video is a 2008 Dodge Caravan with only 1 fan working. Ya original comment is that how could pressure be normal if fan not working. That was explained in my second comment to you. What part of this exchange is the dis agreement? The car need both fans to operate properly. Are you suggesting that it dont? Or are you suggesting pressure can't be normal if both fans not working?
Only 1 fan will run while the AC is on... The other is for when the car gets hot.
Thats not true on this model. True maybe for others tho.

Give the back of that fan a little tap on the back with a wrench that boy will come back on. Fixed.
This is the differance between a real mechanic and a parts swaper this guy os a part swaper
You prolly should explain it to us, we not sure of the difference.
He is going to put a whole new set of fans rather than fix the one that quit its a dc motor find the break in the wire open the can find the problem like brush not contacting or in some they put thermal fuse ive even had to solder the armature wire throughing the whole part out is china style worst case if determined the motor cant be fixed get one from the junk yard that works with busted fan plastic or what ever replacing the whole unit means you learned nothing but how to throw money at it
@@sean7058
And at standard hourly rate what would the cost be for him to disassemble the fan and start poking around and hoping it’s something easy to fix as compared to the cost of just replacing the fan with a new one that is guaranteed.
When you’re doing something on your own at home your time is free so you can spend four hours fixing a fan.
Which of these days would be about $400 worth of labor for $100 fan.
@@sean7058 you’re talking more labor especially if that junk yard motor does work most of the time the extra the new part cost is equal to or cheaper than the more labor I’ll quote you to go a different route
Okay I see 👀
What up Chic
And also the new 1234 freon is terrible at idle because it operates at a much higher pressure than 134r.
That’s a Dodge Grand Caravan/Chrysler Town and Country, they were still using R-134a on these vehicles.
@@jamram9924 yeah absolutely. But, the new Freon is not as good as 134. My 02 f150 was much better than my new one
