Most likely the blower motor resistor has failed. There is a updated version from GM that is much more durable.

2006 chevrolet silverado all fan switch works but 5th which is high?


Check blower motor resistor sit next to blower blower housing, will have a seven wire plug going into it, and two wire's coming out red & black that go to blower motor, remove resistor and check voltage at little resistor on back of blower resistor, if no voltage going across while you have it on high, bad resistor. Hope this helped.

CHECK THE BLOWER RESISTOR AND THE CONNECTOR. THE TEND TO BURN TOGETHER.

THE RESISTOR IS BEHIND THE BLOWER ON THE PASSENGER SIDE OF THE TRUCK.

A DEALERSHIP USUALLY CARRIES BOTH PARTS AS THIS IS A COMMON PROBLEM.

Heater not working


The problem is probably the blower motor resistor. I'm not sure where yours is located exactly. They can be on the firewall under the hood or some are near the blower motor under the dash.

2004 Chevrolet Silverado Heater/AC Blower on without Ignition ON


there is no relay for the heater fan it's a 15 amp fuse and is on the accessories circuit. the reostat is responsible for all 3 speeds .with the key off there should be no voltage to the blower motor whether the fans speed fan switch is on or off. the fuse will be located in the fuse paneleither on the drivers left side in the dash or underneath the dash in the fuse block. you have a short in the harness that is under the dash and most likely it's a bad plug on the harness. your going to have to do some searching but that's where the problem short is... please rate
