I have a 2004 chevy 2500hd that had the battery go dead. After getting the battery jumped my airconditioning only blows hot air. I have started and stopped the vehicle multiple times , checked all the fuses and all other gauges appear to be working with no problems. I have driven the vehicle two days with no other problems. Any ideas what could have happened when the battery went dead.

My mother-in-laws is doing the same thing, but only one side is blowing hot. The backlights on the A/C control, passanger side air bag and headlght cotrol knob stay lit and drain the battery. I think something in the control unit is shorting. I plled the A/C unit and am waiting for dark to see if all the lights go out. I found a place that sells the control for half of GMC/chevy. If you have figured anything out please email me. Thanks Wes

My battery went dead ...jump started and every thing was working, had the battery replaced, and now the AC blows hot air. Any clues? All fuses check good.

Has anyone had any issues with 2004 Chevy Silverado 2500 HD Diesel truck & the injectors going? I think this truck has been a lemon since we purchased it nothing but problems or the mechanics at the dealership have no idea what they are doing.

Very frustrated!!!

ok all of your guys problems are simple! and can be simple. for the ones that the battery is drainin for no reason...you will have that with a big truck. they use alot of power....

then the whole air thing...that would have to be hooked to a computed at a dealership or autozone or something and they can tell u wats wrong for sure..im guessing a vacum tube or connections between the alternator and the engine...
