#510 of 779 Heater Defrost Problems by 44magnum Dec 12, 2006 (2:32 pm)
Hi, I have an 05 Yukon Denali XL and I am having problem with the defrost side of the heater. I took it to the dealer and they told me they thought it was a motor. The main blower motor is working fine. The problem is when I change from floor heat (or any of the other settings) to defrost the air will not come through the defrost vents. It also blows cold air on the passenger side and warm on the driver side when all the way on floor heat. I can hear the air flow change when I switch it so to me it does not sound like a motor problem but an adjustment problem. Is there any adjustment on the internal doors of the heater box? I appreciate any help with this. One side note. This was working fine until I took it to the dealer when it was running rough. They said it was an oxygen sensor and replaced it. It helped somewhat but it is still a little rough. As I left the dealer my windows started fogging and this was the first time I noticed the problem. They said it was not related to what they had done and I really can't see how it would be either but then again???? I would appreciate any ideas or help. Thanks in advance.

Replying to: delfina1 (Dec 10, 2006 5:41 pm) Hey shade-tree mechanic, As I ponder your diagnosis I think you hit it right on the head. Your explaination make perfect sense. Due to the holidays I probably won't be getting it back to the dealer till after Jan 1. I will, however, let you know the final results when corrected. Thank you very much for your input.
#512 of 779 2004 Yukon Denali Speedometer Problems by hiten Dec 26, 2006 (2:30 pm)
I've got an 2004 Yukon Denali with 60K miles on it and haven't head any major problems. On my trip from Charlotte NC to Chicago IL, my speedometer started having problems. I was doing atleast 75mph and it was registering 0 MPH. Temporary fix was to turn the truck off and wait for few minutes. This would work fine for about 60miles and then the speedometer needle would start going back to 0. Has anyone experienced this problem? All other gauges are working fine. If yes, what was the root cause of the problem? As of rightnow the speedometer is working fine, but I am not sure how long it would last. Thanks in advance!

Replying to: hiten (Dec 26, 2006 2:30 pm) Its prob the speed sensor on the tranny. Shouldn't cost too much. I'm not positive bit thats what it sounds like and atleast its a place to start.

Replying to: delfina1 (Dec 10, 2006 5:41 pm) Hey Shade Tree. The headlight flickering has stopped. Do you think perhaps the voltage regulator adjusted itself or was sticking from new and has now wore in??? Thanks again!

Replying to: ljackso1 (Mar 04, 2006 8:20 pm) Jackso; My GM dealer told me that with the ALLwheel drive, the two differentials have to have some slack so as not to bind. The clunk is not brakes, but the xmission taking up slack in the shafts conncetion. 25K on it now and is ok pulling 7k pound trailer....coachman99

Replying to: mydenalixl04 (Mar 20, 2006 4:34 pm) I had to go to the dealer and have him reset the computer on tire pressure, and this will happen also in cold climates if the tires get too low before you correct the pressure, keep them about 4 pounds higher and it won't happen again....coachman 06 denali xl
#517 of 779 YUKON XL HEATER TEMP PROBLEM by johnnycab Jan 03, 2007 (10:40 am)
Here's my dilema... I have a 2000 Yukon XL and I'm having the following issues with the heater temperature in the driver/passenger section of the cabin, rear temperature control is working fine. The climate controller works fine(temp can be controlled from cool to hot and vise versa)but when the truck warms up(~10 mins on the road)the controller can control from cool to hot but it does not go from hot to cool, in other words, it gets stuck on hot and I mean it is hot. The only way I can get it to go to cool again is if the truck is off and remains off for ~15-20 mins. I know that the controller is working fine because I have replaced it and it did not fix the problem. Anny ideas??? Replies to this message: randyt1 (Feb 05, 2007 9:30 am)
#518 of 779 2003 Denali xl paint peeling by nrogers Jan 07, 2007 (4:01 pm)
We love our new(used) Denali. We had a Suburban xl but wanted the slightly larger engine and found a hood deal on the Denali so bought it. The only problem is the console is painted and it is peeling. I cant for the life of me figure out why GMC would paint the plastic instead of just using colored plastic. Is there any way to fix this? It looks so cheap to me.
