Heater problem
1991 Chevy Truck V8 Four Wheel Drive Manual
we cant get the heater/ac head unit to power up even though there is power there on several wires. we have replaced the wiring harness, computer, selenoids, blower motor, head unit... pretty much everything in the cab that relates to the heater

Is the problem that you are not getting heat or the blower motor doesn't work?
