Question about 2004 Volkswagen Passat
I have an air conditioner problem on a 2004 Passat. I have voltage at my a/c compressor but the compressor will not engage. I cannot seem to locate a suction pressure switch to see if it is bad. Alos, I casnnot find a schematic to show me where the ac/ relay is located. Any help would be appreciated. Ihave checked the lin pressure and there is sufficient pressure on both sides of the compressor (looks like it has equalized)
the a/c pressure switch is located to the left side of the condenser radiator, as you stand in front of the vehicle. you may have to remove the bumper in order to get access to this switch.
there are 2 relays dealing with the a/c , numbers 16 and 17, on the relay plate at the drivers knees, the plastic panel will have to come down. 16 is the clutch relay and 17 is a/c control module.
hope this is of some help
