| I have a 2003 Gmc Sierra 1500 with dual heat control. The air conditioning works fine but when you slide the controls up to heat the heat only works on the drivers side and the passenger side still blows cold air. This happens whether or not the AC switch is on or off. Thanks in advance. | |

Replying to: tsh1282 (Jun 26, 2008 10:39 am) Only thing is, my a/c will not put out very cold air. It has a good charge of freon (had it checked) and I suspect the cold/hot air mixing valve. How do I check it for sure? |

I have 03 GMC 2500 HD with the digital climate control. My problem is that i can only get hot air when its set on 90 degrees, anything below 90 is cold air. Any suggetions would be appreciated.

Replying to: trijet (Nov 04, 2008 2:02 pm) Mine is a 2006 GMC Sierra with 50,000 miles/ no warranty. The wires/connectors that come out of the fan/ resistor box by fan look burnt if you look closely. My dealer also had the resistor/wiring harness in stock. I commend your dealer for the fair "goodwill" N/C repair. email your dealer/ service manager contact? |

I have a 2007 (NBS) Silverado 1500 with digital climate control. I was into the under the hood fuse box searching for a switched circuit and didn't think to disconnect the battery until I had been poking around for awhile. Now, the heater blower works in all settings ( auto, manual, defrost, etc.), but no heat regardless of how high I set the temperature. Will appreciate any help, ideas, suggestions...

Replying to: karmac (Dec 08, 2008 6:40 am) Turn off you climate control, then try disconnecting the battery again for 5 - 10 minutes. Then put it back on. Just disconnecting doesnt reset the computer it takes a while of no power. With a 1500, I imagine you only have 1 battery but if you have 2 make sure to disconnect both.

Replying to: tthoreso (Dec 08, 2008 8:07 am) When I left work at noon yesterday, I discovered that the remote start was also inoperable. I did as you suggested, turned off the HVAC and disconnected the battery for about 15 minutes. That restored the remote start but not the HVAC. The original problem was my own stupidity! I removed the under hood fuse box without first disconnecting the battery (I certainly know better). Since resetting the computer by disconnecting the battery didn't fix the problem, I suspect that I have fried something in the HVAC circuitry. Have any suggestions short of taking it to the dealer? Thanks for your help |

I shorted out my heater control last night. Is there a quick fix or a location of a relay or fuse that I can check. Thanks! James |
