03 yukon denail rear blower keeps running when truck is turned off.
I bought the truck summer of '23. An animal made a nest in the blower and it made a horrible noise. I got it cleaned out and reset the HVAC and everything seemed good. Once I replaced the stereo the rear blower keeps running after the truck is off. I disconnected the resistor at the time, and... -

AC has me stumped
I have a 2004 and Escalade, It has the digital HVAC controls and the rear air. About 5 years ago, I upgraded from the mechanical engine fan to the electric engines fans. I used stock parts and had the computer reprogrammed, so it functions more like a 2005/2006 with the electric fans. It has...- fish1534

HVAC controls not telling blower to turn on, intermittent
Wife texted me saying the 2011 Tahoe we bought recently isn't enabling the front blower fans, but rear controls worked fine. I got in today and everything is fine. Should I pull the dash apart and make sure there isn't anything obvious or is an easier check to pull the HVAC fuse and wait a bit?- hillstrubl

1999 Tahoe AC control module
Okay, I just acquired a 1999 LT 4 door with rear AC. This Tahoe has rear defrost and heated mirrors. The previous owner said the control module went out and he couldn't find one that looked like the original (for some reason he tossed it and now I don't know what it was). So, he went out and got...- ariding88

Weak front air flow problem
Hi all, Trying to figure out a problem with front HVAC before it gets too hot during the summer! My '07 Suburban has the auto climate control setup and when I set the fan to full blast there's only a modest amount of air coming from the upper vents. A/C itself works fine and the air gets cold... -

Clicking on passenger side
I’ve seen one post about this, but the answer didn’t work for me. I have a 2003 Suburban that I inherited when my dad passed away. It is in great shape and I love driving it (especially with the Bose stereo!). It has a problem where there is a loud clicking sound in the front dash on 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

Adding PAG Oil to receiver drier
I am changing my entire AC system on my 1999 2 door Tahoe 5.7. Since I have already balanced the new compressor with the correct amount of PAG oil but since I'm changing the condenser, both hoses, and the receiver drier, I need to add PAG to each of them. I know what amounts to add but I...- ezombie

HVAC / Tech2 help!
Hi everyone. I’m hoping someone smarter than me can help me figure out what’s going on with my HVAC. 2006 Yukon Denali. The driver side has a strange problem. While on upper vents it will gradually get colder until there is no heat at all coming out. The passenger side stays constant. If I...- Darren Gese
