Sounds like a low pressure shutoff switch is working and there is not enough charge of freon, r134a, in the system.

I just put new ac clutch in2006 Taurus and is working great but car running sluggish almost stop running when at a light or stop sign why


The original a/c clutch was probably burned up by the compressor locking up. Possible bad compressor.

2005 Sedona fully charged,compressor does not turn on


Normally you would check for voltage at the relay then the low pressure switch, then the compressor clutch.
With the system charged or the low pressure switch bypassed you should have 12 volts at the clutch and ground. You can also check the clutch with an ohms meter to see if the magnet is open.

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 2001 Ford Mustang V6, the ac is blowing warm air. We checked the refrigerant and it is full. The ac compressor will kick on for a few seconds and then kick off. Why is the compressor not staying...


it's either low (in spite of your readings) or your a/c clutch is not working correctly or you have too big an air gap in the clutch.
First, just disconnect the 2 pin connector from the a/c pressure cycling swithc and jumper the 2 pins with a wire to force the clutch to stay engaged. See if it blows cold then, and stays engaged. You can run this way for about 15 minutes before you have to pull the plug.
report reulsts.

please don't forget to rate.

2001gti vr6 ac not working. Blowing hot air. Is it posible bad module?


First check the ac fuse, if it is ok check to see if the clutch is turning when the ac switch is turned on. If clutch does not engage you should check the ac relay. It is usually located in the fuse box. You can switch places with it and another relay with the same number in the box. If compressor still doesn't run it may need to be charged with R134. If compressor runs for a few seconds and shuts off and continues doing this with control on high. It nees more refrigerant added.

AC compressor only runs when the van is motion. When I stop at a light the compressor kicks of and the cold air gets hot.


your ac compressor clutch is bad and needs to be replaced and honestly it usally better to just replace the entire compressor

AC light blinks and compressor will not run. Freon


Could be bad AC clutch relay. Just replaced mine ($11 at autozone). It is located in the relay box just behind the battery.

Ac stoped working


Another way to know if your Compressor is running is you will see the pulleys rotating, when its off the fan just runs along it until turned on a clutch will engage and the pulley will begin turning the compressor. You will also hear in run, it may or may not shut off and then run again for a few seconds, then off (it depends on the AC System) - Some run all the time, some cycle on and off

here is another picture to help you understand what i mean
