Circuit unit behind the ac controls


sounds like your blower motor has stopped working check for power going to the blower system if you have power the blower is probably bad the concern is the lack of a fuse blowing or a breaker not cycling you may have a harness problem sometimes a low grade short will heat up wires then melt them together causing a multisystem failure even though a fuse or breaker didn't blow check you harness

The a/c on my 2010 Mercury Milan quits blowing after about 2 hours of driving. Any ideas?


Sounds to me like the A/C clutch is no good and out of adjustment.You should goto your nerrest junkyard and get a used assembly take the clutch off then you learn how it comes off and install it on yours the save the pump for later use if needed. The clutch should only have a .010 air gap after install between th inner elctro magnet and the clutch plate it's self.

A/C fan quit blowing, but cold air seems to be coming through the vents. which fuse controls this? I can't find my owners manual. 2000 JEEP Cherokee. Thanks, Chuck


fuse should be third up from bottom on right...25 amp. Or, 40 amp in power distribution center.but I believe that part of system is for ac compressor. If fuse blows again, likely motor is worn out.

The air conditioning,the blower fan everything stopped working, on 2002 Nissan Sentra. Does anyone have any suggestions?


One suggestion. Have you checked the fuses ?

I would check the AC or blower fuse to start with. If you have the drivers manual it will show you where the fuse box is. Typically there are at least two boxes to check. One in the Engine compartment and one in the passenger cabin.

Look inside the lid of the fuse box to see which fuse may apply to the AC circuits or the blower and check to see if they are blow. the metal link between the two posts that plug in. If the link is missing you need to replace the fuse with one of the same rating. Make sure you know where you took the fuse out from and put it back in the same slot if its good. Check all the main fuses if possible to see if any have blown and replace if they have.

Aircondition not working....just blowing warm air.....fan is working


Either you are out of coolent or the compressor is not working.

First check the fuses, then lift the hood and have a friend turn the air on. The compressor should cycle, if not take it to a mechanic. If it does cycle you are low on freon, take it to a mechanic for a system charge. Make sure they check for leaks first.
