Hi my name is Andrea,
My Yukon is doing the same thing. I was wondering did you ever get your fixed and if so what was the problem. Please inform me because I have not had my Yukon for 4 months and the dealer is about to get it all.

Picked up vehicle last Sunday with 300 miles on it. When I restart my 2007 Yukon xl (Not Denali), my heat only comes on after I change the heat settings a few times. The temp gauge is up to near 210 but no heat. I have to adjust the flow direction. Went to the dealer yesterday and they said it was normal. Any suggestions would be helpful.

jlflemmons-
 
Thanks for the great tip! I recently replace my battery on my '04. Well, when heater is turn on the passenger side blows Hot air but, the driver side blows Cold air; "very cold".
 
I called the dealer and they didn't have a clue but wanted to keep my GMC for a few days.
 
I think your reprogramming will reset the system. . .thanks --Los Angeles, CA

Mine is a little different than everyone elses. when it's cold out.. say in the 20-30s it takes forever for the defrost to start blowing... either hot or cold...
 
in the summer sometimes it takes mins. before the a/c will blow....
 
no problems with air temp.. just the time lag for it to blow any air at all...
 
anyone have a clue?

This sounds kind of like my problem with the 01. Due you have the auto climate control? Does the rear blower work, even if the front one does not? Let me know this, and if this is the case, I might be able to help you.

yes.... rear works as designed and the front is the only one that gives me problems. it has auto and i'm tried the fuse reset... maybe i'll try it again just longer.
 
ok this morning it was cool 45degrees and it took awhile to come on. now it's 65 and it will turn on real quick... if it's 100 the a/c will take awhile to blow
 
but rear air is normal in all aspects

not sure... it works and works well.. but, it has to finally decide to turn on and once it has been going for awhile it will turn on instantly.
