Ac is not blowing out cold air. You have to put gages on the system and it shows its has freon.Checked all fuses and relays. The two fans in engingine compartment do not come on when the ac is turned on but does when the engine gets hot. The compressor engages when turned on also.
If the magnetic clutch engages the compressor and still no cold air could be still low in freon or the HVAC unit.

Blower motor not working all the time...if I bang the dash near the glove box, it comes on then works great. Is this the switch assembly, the resistor problem, or should I be replacing the blower motor?

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.

My 2002 Expedition air conditioner will sometimes blow hot air and others cold air


I would check the following possibilities:
1. Is compressor clutch working? - You need to do this when the ac is blowing hot air only - locate compressor drive pulley on engine - rubber belt wraps around it. Start engine and set to max ac. When the ac is blowing hot air, look at the center of the compressor drive pulley using a good flash light - watch it for a while, it should be spinning with the pulley - this means the compressor is engaged. If not, the compressor is not engaged. If your ac is blowing hot air, then the compressor should be engaged and running (trying to cool). If it is not engaged, then your compressor clutch is probably going out. Could be low voltage to clutch, but more likely the clutch is worn out and only working some of the time. Note: if working normally, the compressor clutch will engage and disengage in cycles- but the air should always be cold. If clutch is bad, compressor would need to be replaced (sold as one unit). This is tricky to diagnose and could take some time - you need to do it when ac is blowing hot air but set to max cooling.

2. Low on refrigerant or refrigerant has moisture in it? If your ac blows cold initially after being off for a while, then heats up, and continues to regularly cycle back and forth between hot and cool air, then the system may be low on refrigerant or the refrigerant may have moisture in it that is freezing and restricting refrigerant flow. An a/c shop can check refrigerant level and even replace refrigerant if moisture is suspected.

Could be other issues, but I would start with these.

Good luck

Blows hot air clutch does not engage compressor. ac switch on fan blower on high replaced ac diode cause it kept blowing 10a fuse


you either have a power loss problem but more likley your low on refrigerant. if its low, there is numerous pressure sensors that will not allow it to engauge to protect the compressor. you got to put a gauge on it. standing system at 80"F should have about 80-90 lbs. standing pressure.

AC N MY CAR


Brushes on the motor may be going bad. Blower motor is in engine compartment under wiper motor assembly. The blower motor regulator is under the blower motor. There is an A/C relay behind the fuse box under the screwed down cover.
for lack of motor speed its probably the brushes on the motor or the regulator. If no cold air your charge is probably to low to engage the compressor.
