2004 Tahoe AC question

[nc87k5]

Does anyone know how the dual climate control on a Tahoe works? I just replaced the battery and when I cranked the truck, the passenger air vents were blowing hot air instead of cold air, even though the temperature selector was on cold. I'm getting fed up with this thing . I've replaced the speedometer cluster, the intake manifold, I have a small short in the "key-in-ignition" chime which the GM shop says nothing major will happen except the rear speakers will go out, and now this. They sure don't make them like they used to! Any help would be appreciated.

We had the same issue. I may be off some but. Pull the fuse for the A/C for 5-10 minutes. I can't remember if you leave the key off or on. The A/C system needs to reset. There may be a TSB procedure on it. Our dealership is actually the one who told us how to do it, it's just been a while.

I was off some but that should help you out

Sweet, thanks! I did however start it after letting it sit for 30 minutes and it's back to normal now. I will save this for future reference though.
