Questionok i have a 1992 buick lesabre,the a/c started cutiing on and off so i recharged the system. it continued so i thought the blower motor was shot so i changed it still nothing.when i turn on the a/c the compressor turns but no blower motor comes on. nor does the defrost, vent,or heater come on can you give me some help on this if you can thank you!
AnswerHi Jeff,
Sounds to me like a switch, like maybe the selector switch.
There is a resistor pack, but it is bypassed in Hi, so if the blower doesn't work, it could be the switch, the blower relay, a fusable link, or wire connections. See if any power is getting to the connection on the blower motor, and also check the ground wire.
