Dorman 599-003 Remanufactured Climate Control Module Compatible With Select Cadillac/Chevrolet/Gmc Models

Works great and installed quick and easy.

It seems to function, but the panel is getting hot. I don't think it was rebuilt with the correct load ( total resistance) built into unit, poor engineering tolerances. 1/13/22 the front slide heat regulator snapped off in -30C weather, when I went to start the truck and adjust heat. Amazon is going to give me some money back. I ordered another module from a different company. It is not built the exact same way, but it is working, both are Dorman rebuilds.

I cannot remember when I actually installed the unit, but it has only lasted about 2 or 3 weeks before it stopped working. Worked great until yesterday. Started the vehicle and no air was coming from the dash vents and not cold (compressor kicked on, but no cold air). Tried adjusting the controls through their range, but air would only come out for defrost and the floor. Pulled the fuses to reset it, but made no difference. Fortunately I still had the old unit, so I reinstalled it and now the A/C works great again. The only reason I replaced it to begin with was the backlights had stopped working in the original.

Bought this unit for an 09 GMC Sierra 3500. Very easy to install, reset instructions were also easy to follow, thanks.
