AC Switch on Chevy Truck......how to replace

Question

Registors on AC switch on Chevy Truck. Speed 5 went out then 4 went out and now all speeds are out on the AC Switch.

Does anyone know a particular repair manual that will guide me through repairing or replacing? Any help will be appreciated.

Answer 1

Well you didn't say what year your truck is... Most likely the resistor and the connector is burnt up. It is on the passenger side bolted into the bottom of the air box by the blower motor.

Answer 2

The electrical section in a haynes manual is one of the best.
