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.

TIA
Clay

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.
