I have a 2000 GMC Savana 3500 and I am having troube with the H.V.A.C Blower Motor. For the longest time the blower would only operate at either lowest or highest speed. Now the blower will not turn on at all. Would this be a problem with the controls or the motor itself? How could I test both of them? All fuses seem to be ok, anything else that could be checked?

Need help ASAP.

Thanks
Scott

 

Probably a burnt up resistor & pigtail. Unplug resistor wiring & check for melted stuff.

 

Buy a new resistor and you can buy the fan switch without the rest of the assembly. Make sure to match the switch because there's two that look almost identical.

 

I replaced the one on my '97 for less than $30. easy to do. Check YouTube.
