#1 of 369 Chev Silverado Dual temp heat control problem by mikerae

Apr 17, 2006 (9:59 am)

I have dual heat control for driver and passenger. Problem is my side blows heat all the time regardless of setting. You can turn the temperature on both to coolest setting. You reach across and feel the air coming from the vent on the passenger side its cool. The drivers side is screaming hot.
Any ideas?
Truck is a 2003 1500HD LT Silverado 4x4.
Thanks in advance - Mike

My '04 is actually at the dealership for this same problem right now.
 
They tell me over the phone that the problem is/was the door control mechanism on the driver side temp control. I'm guessing that this is a fancy new term to describe the temp sensor not activating the hot/cold doors when the thermostat in the cab called for more or less heat or cold.

I have this problem as well. I asked the dealer to fix it once. They messed around for an hour, then told me all was well. Worked for about a week. Now I am out of warranty. Does anyone know what the GM line is on re-do's of warranty repairs that did not take- after you cross the 3/36 mark?
Thanks,
Don

I have a '93 silverado and I keep going through heater cores. I've replaced it at least six times, some as little as two months in between them. I am being told that it caused by a stray electrical current, something not grounded right. I have pulled the fuses one at a time and checked for currrent in the radiator, but it still is there. I can't seem to locate where it is coming from. Can anyone help me with this??

#6 of 369 95 Silverado Blower Motor not working. by bfbchevy

Aug 05, 2006 (11:02 am)

My 95 Silverado blower motor has finally stopped after some days working and some days not. Once it came on it would run all day until I turn off the engine. But, when I started it back up there was no air coming from the vents again. Hours later or the next day or two, it would come on again. Until, last week. I've replaced the blower motor (passenger side underneath dash), resistor (behind the glove compartment), and checked ALL fuses left of driver and under the hood, and still the blower motor does not run. A/C comes on but no air from any of the vents on any settings, heat, a/c, defrost, floor, vents, or combination. Anybody out there who has any advice, please help, ITS HOT, I'm listening.

My 95 GMC Serrea AC will not blow cold air. The pressure is right in the system. The compressor run right. The air does get colder when running at freeway speeds but warms up at lower speeds.

Similar problem in GMC Sierra was solved by replacing the A/C control module in the dash. It is a circuit board that cracks easily and causes this problem.

#9 of 369 A/C Problem, Noise under hood by kayakking1

#10 of 369 A/C Problem, Noise under hood by kayakking1

I have an A/C problem that only acts up occasionally. The A/C will only come out of the floor and sides and not out of the front vents and when the A/C is turned off it makes a noise that almost sounds like grinding. When the A/C works it doesn't make any sound and everything works fine, and blows nice and cold. Please and suggestions. Thanks in advance.
