02 Denali no ac front vents

[Kingjay239]

Hellooo, so when I first got the truck the ac was working perfectly, one day I left my lights on and etc only to come and find out that the AC wasn’t blowing through the dash vents only through the windshield vents and floor vents. Also rear ac works. Now I’ve been doing a bunch of reading and I want to try the removing fuse method first. But everything says to remove the HVAC/ECAS fuse. But I’ve looked under the hood and I cannot find that fuse for the life of me. Is there a different fuse that I need to remove for this year model?

2002 Yukon Denali short version please hellllppp lol. Thank you in advanced.

If shutting the car off doesn't work to reset the actuator, try disconnecting the battery for a few minutes. The Mode Actuator is probably stuck. Where in Florida are you? Know anyone with a Tech-2?

Try this reset procedure. It’s worked for me more than once.
