Heater problem
2003 GMC Sierra V8 All Wheel Drive Automatic 154000 miles

The fan speed button doesn't seem to work. The fan runs at one speed aall of the time which is a low speed. It continues to run after the truck is turned off and drains the battery. Is there a relay or something that I need to replace?

Do you
have the same problem?
Yes
No
