The indoor and outdoor unit have separate breakers,so one can run with the other.It would not cool. Check the separate breakers to be sure their on.Take the cover off the t-stat, you will see a red and a green wire.remove these and touch them together.If the fan runs you probably have a bad thermostat.If it does not .The problem is inside the indoor unit.There is a disconnect or breaker on the cover. remove it, pull the cover off and put the dis connect back in.If the fan hum ms or turns slowly you have a bad capacitor or fan motor. Try the cap. first,if still not running the motor is most likely the problem.Should the motor not try to run or hum,it could be a blown fuse, you will see it in a small circuit board if you have one.It could be the circuit board itself,or a bad fan relay.A meter can help you trace this if you have one.Be careful as there is 220 volts powering this unit.Good luck

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.

I have a 06 2500 dodge sprinter and the fan control speed wheel isnt working. Settings 1-4 will not work. I can feel hot or cold air coming out of the vents while I'm driving but cannot adjust it.


I have changed the resistor 2 times for the same problem. Its under the hood behind the fan motor insulation.
Mine burned because of fan motor frozen & stuck in the winter. Solution is to let the engine warm up before turning the fan on.
Cheers, Brian

{: ) The popping sound you heard is caused by the sudden movement of an HVAC door, most probably coming from the recirculation door actuator (right dashboard area) or the mode actuator( mid dashboard area). The fan outputs could be normally working, but is being muffled by the incorrect positioning of the HVAC doors, giving an impression that there is fault in the blower controls. In other words, your vehicle is having an air distribution issue.
If there's no conflict in your climate settings, then the trouble may be in the HVAC doors binding or broken, or the actuators faulty or sticking. In both cases, servicing may involve removal of the dashboard to access these HVAC components.

Hot air comes out of defrost vent at top dash and cold air out of


Hey, what setting is your A/C on Max AC? AC? Cycling air in vehicle or taking it from outside

The car icon on the right in this image is what I'm referring to when I say cycling air in vehicle.

Also, do you ever have cold air blowing? on any setting or any speed? if not, find your A/C fan, it is smaller the the engine cooling fan, sometimes there are 2 fans together. The AC fan should be located at the front of the vehicle and is usually electrically powered.

Also try to find your compressor, looks something like this:

is it running? is one pipe hot and one cold? (the pipes I am referring to are inlet and outlet pipes of the A/C compressor unit.)

Hope this helps, keep me posted

Air conditioner works but not blowing out the vents


Check the air directing servo motors under the glove box. they are 2 black boxes about 3"x3". you have to clean the contacts of grease with contact cleaner spray or alcohol.
