2003 Chevrolet truck heater controls
« on: September 25, 2012, 10:35:00 PM »

I have a 2003 Chevy truck, 3500 Dually and it has separate heater controls. The drivers side stays hot all the time no matter if the A/C is on or not, the pass side is adjustable, no issues. Is there a electronic sensor or how do I trouble shoot this? It just started tonight.

Those who said it could not be done, should not stand in the way of those who are already doing it!

They can down load the power unit to test it. I just had to replace the power control on my 2003 Chevy Duramax for the AC unit, about $800. Make sure the knob is turned CCW to the cool side.
