CHEVROLET CAPRICE BLOWER MOTOR PROBLEM

1989 Chevrolet Caprice • 71,000 miles

The blower motor doesn't work at all, the blower motor, relay and resistor are new, and the a/c fuse is good. What could it be? If you put a piece of wire in the power end of the relay plug and put it to the other end of the plug to the blower motor power the blower motor comes on, so the relay has power but its not getting any signal to power up the blower motor. Where could the power be lost?

Back at the control head. It sends current to the relay, for high speed, and the resistor for varying speeds.

Start with voltage checks there
