HVAC Issues...

Sorry wrong section. Please move

The Problem: Truck blows hot air all the time. Weather its on cold setting or not there is hot air flowing gently out of the either upper or lower vents (depending where I put it). The auto temp. control function only seems to work well when its quite cold out. Its then I can notice the fan speed slowing if I turn down heat.

Its appears to be the front controls only that are not working correctly. I believe rear is functioning correctly.


Thanks ! Just need a little direction!

Cheers

Same problem here. I can get the vent controls to work, but even when turned off, I am still getting hot air coming thru what ever vent setting I have it on.

Have either of you replaced your battery recently? Here's a link to recalibrating the HVAC, it might help. http://www.tahoeyukonforum.com/threads/recalibrating-hvac.81057/

Yes, I had the battery replaced. I found a topic on the recalibrating the HVAC, and that worked. Just need to replace the clutch and pulley on my compressor, it makes that banging noise when its engaged.

Thank you sir. This worked.

I did replace the battery a few months ago. I cannot recall that I noticed the problem happen then or not. I could assume it did based on your posts.

Either way I am back in business.

So thank you again.

You're welcome. Glad it worked.
