Hi All,
My 2004 MK4 wagon's A/C started blowing warm last week. Using other posts I have found that my large fan had quit working, and replaced it. Both now run on low with the key in the ignition and A/C button pressed.
I also found that the compressor's clutch is not engaging. Yesterday, I turned on the car, had the A/C turned on at maximum and measured the voltage getting to it (I unplugged it and measured at the car side plug- in case that matters).The voltage appeared to vary, it would hang out around 7 volts for a few seconds then spike to 10 volts, and come back to 7, etc, etc, etc. Is that normal? Shouldn't it just be 12 volts?
I didn't know enough yesterday to check the resistance of the clutch coil, I hope to do that tonight, and also apply 12 v directly to it and see if I can engage it.
Any other help would be appreciated.
