2001 chevy silverado extended cab
My a/c blower fan does not work on the first two
speeds. It does work on 3-4-5 speeds. Where do I need to start looking?
Does it have resistor strips?






JK:
Thanks for your question and visit.
Yes, the a/c system does have a blower motor resistor assembly under the passenger
side of the dash, next to the blower motor. That does sound like the most likely cause.
The resistor recieves voltage from the fan control switch on the a/c control head, and
controls all speeds except HIGH. High is a different fuse and circuit.
