#264 of 310 Stereo Problems Plz help
Sep 21, 2011 (9:52 am)
Not sure if anyone is familiar with the hooking up the stereo in a 2002 yukon. I wasnt but i figured since it was a simple harnest and not the more expensive one that is used in later models. I figured I would give it a try well I got the aftermarket deck hooked up but could not get any sounds from the speakers only my sub and amp were working but no vocals. So I contacted the harnest 800 num and they made me aware of a pink wire that was supposed to be ran to the power wire which i did still no vocals. So I figured forget it i would put the factory back in and run a high/ low adapter to the speakers so i bought it but was not sure whick speakers to hook it up to it just says right and left but the wires arent labeled from my truck so as im guessing i get a little spark andy my dash lights go out like no fuel light no PRND321 only turn signals on the dash. so i give up man is there anyone that thinks they can help me out im in over my head with this one its a BOSE system BTW Thanks
#266 of 310 2001 GMC Yukon Heat stays hot
Sep 23, 2011 (11:54 am)
When i turn up the heat on my Yukon XL it stays at full unless i turn the car off then turn it down to cold again and start the car. The AC works fine unless hte temperature dial gets turned to hot then it wont come back. Any ideas?
#267 of 310 04 yukon xl only blowing on windshield vents....
Oct 01, 2011 (5:35 pm)
I had the problem of the ac switching to heat. With winter coming up I dont care if the ac was not working correctly but I tried to recalibrate the system by pullling the fuses in dash and under hood and disconnecting the control panel. Now the problem is air wether hot or cold only comes out of the defrost/windshield vents, no matter what setting I use. Is this now a problem of the blend door actuator?
#268 of 310 2007 Tahoe only blows from face vents
Oct 04, 2011 (1:31 pm)
My 07 Tahoe will not run heat or air to any vents other than the top vents. The selector switch seems to work fine, as the light is on, and if you press the rear defrost button, it works. I just need the FRONT defrost to work....
#269 of 310 2003 Yukon XL AC Problem

#270 of 310 Thermister or Resister
Oct 22, 2011 (8:44 am)
My 2005 Suburban Heater started running at full speed, even when the Truck was turned off. I read several posts about replacing the thermister, which I did, but now nothing happens. The heater and AC wont run at all! The thermister was after-market and required cutting off the original 3 wire connector and splicing the new Thermister in and the auto parts store did show me a picture of the original part plus the after-market one so I think it was the correct part, but all I can come up with is that it was defective. Any ideas?
