O.T. GMC 1500 Blower Motor

Anonymous-0 · Apr 23, 2011

I have a 2000 GMC 1500 most of the time the fan for the HVAC works fine, but ocassionally the fan will not run at any speeds, replace breaker and checked fuses still have the problem ?

I would first check the motor ground wire followed by the connector(s).

Probably time to replace the fan. My daughters 99 olds Cutlass did the same thing. Would work, then it wouldn't. Thought it was the connector, but finally replaced the fan. No more problems.

Is the motor under the glove box? Check the wiring at the resistor next to the motor.

Under the glove box is a wiring harness with about 10 wires. Turn your fan on, if nothing happens then wiggle the wiring harness (some times it takes quite a bit of wiggling). Chances are that will solve your problem. The connectors have a tendency to corrode over time. I have 2000 and 2006 Chevys, both have developed this problem and I've taken the connectors apart twice each to clean them thoroughly, which solves the problem for about a year, then it redevelops. Hope this helps.
