: Some A/C Wiring questions. 77CDV

08-06-13, 10:48 PM
I started work on the A/C, I just replaced the blower motor, and am waiting on a new relay for it.
I tested the relay socket, and found one thick hot wire to power the blower, the power wire to the blower, and another wire that comes on with the ignition.
I was wondering if the other small wire is supposed to be hot when the A/C is switched on.
Also when I turn the A/C on I can hear the compressor clutch come on, even when the car isn't running, and there is very little refrigerant in the system.
Is this a sign of a bad low pressure switch, or bad wiring to it.
