Up for sale is a GM Truck Heater/AC Control.
The control is in good used condition.

This is a used Dorman brand control.

The controls move smoothly but I don't have any way to further test it.
All of the back illumination lighting did work when power was applied (slider, see 1st 2 pics).
Wiring plugs/pig tails are not included.
The compatibility list includes many makes and models but is not all inclusive.
Please verify fitment before purchase.
The item that is pictured is the item you will receive.
This would be a great replacement if yours doesn't work.
