Question about 1992 Buick LeSabre
Checked the two fuses on the car and jumper the low pressure and high pressure switch tested the coil on the a.c. unit. The fan motor runs but could not find a a.c. relay and the fan on the cooling system only runs off the temperature control but not when the a.c. is switch on . could not find a wiring digram of the system.
The a/c relay is out under the hood on the firewall with several other relays. The problem is probably the body control computer, or the a/c selection switch.
