Default heater a/c fan not working
95 LT1a/c& heater fan not powering on. All fuses ok, as well as the relay. Replaced command module in dash. Power is present at fan but it doesn't come on. Any one have suggestions? thanks

Make sure your ground wire to the fan is clean and tight. You can use a test light clipped to power and touch the ground wire to see if it lights up. If it does, then your blower motor is suspect.

I'veowned two GM's with a loose blower connector - '98 Jimmy, and '02 1ton Express (bought new).
