23 Yukon AC cooled seats suck
2023 Yukon SLT. Equipped with “AC seats” in the front. Only problem is I don’t notice the effect at all. I can hear the fan running in the seats, but feel no air coming out. Anyone else have this issue? And if so, what did you do to resolve? Might take it in to the dealer, but I’m sure I’ll be... -

Interesting AC Issue
Had an AC leak. Looked everywhere with my freon sniffer and couldn't find it. Finally had to bite the bullet and take to a shop. They spent two days hunting and finally found it. An AC line runs all the way to the back of the Yukon and the leak was in the line back there. Had to have the... -

I have 3 issues with my 1999 Yukon SLT, all of which are electronic related.
So I have a 1999 Yukon SLT I bought used. I'm having 3 electrical problems with it that are most likely not related but I figure I'd pour it all out in case one might cause the other. Let me preface this by saying I am not a mechanic. I'm not even a vehicle hobbyist. It's just my daily driver...- gtrman90
