I have never personally heard of anything like what you described happen. I frequent several GM boards none of which reports anything like above.
If you find your dealership hard to work with on warranty issues, give GM customer service a call and they usually can refer you to another Chevy dealership in your area. With what you describe, I don't think that the dealship can question or deny warranty coverage as the results (burnt wiring) is obvious. Probably due to a ground condition somewhere along the wire.

I am also currently having this issue i have a 2005 sierra 2500 with 20,000 miles the thing is only used during the winter and my heat /ac does not work brought back to the local dealership where i bought it from and was told a bad relay caused the wiring harnes to burn up and was quoted 300 to fix i think that is b.s. it is obviously a factory defect i called gm cosomer service and they offered to pay for half but will not cover the whole repair. the tech at the local dealership said he sees this all the time obviously they have a problem.

As a follow up, I just got back from the dealership. I was 3,000 miles out of warranty and the cost to replace the resistor and wire harness was quoted at $340. When I asked for the number to the customer service rep because fried wiring is not normal wear the service writer had me speak to the service manager who stated that this is such a common problem that they have all the parts on hand to fix it and for "goodwill and to fix a known problem" they would fix it for free. One hour later I was down the road with it fixed.
Thanks for the inputs.
#188 of 375 2003 Sierra heat problem
Nov 17, 2008 (6:11 am)
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.

I was jumping another person's car and accidently got the cables on the wrong posts. When I started my p/u it only put out hot air. I talked to the Chevy dealer and he said they would have to re-program the a/c computer. I thought if it was like other computers I would just re-boot it. I unhooked the negative cable from the battery for a few seconds and reconnected. It fixed it.
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?

#191 of 375 GMC Sierra Climate Control Problems

I had the same problem; replaced the burnt resistor and wiring harness ($170); called GM Customer Service and was told that I needed an official diagnosis from the dealer in order to have a Dist. Rep. call me to discuss the problem.
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?
#193 of 375 Climate Control Problem
Dec 08, 2008 (6:40 am)
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...

Not sure what the original problem was but if you disconnected the battery you could have flipped the computer, which I had done.
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.
