Mine is a bad blend motor on passenger side. It's a pain to get to. I finagled it and got it put in ac blend mode and pulled the power to it so it's stuck blowing cold. I think the driver side blend actuator is easier to get to, at least on mine it would be.

Turned out in my case when we had recently replaced the battery there is a reset you sometimes have to do. We did the reset and never had another problem. Much easier to start with that instead of pulling apart your dash.

I noticed that the ac settings had changed from what is typical for me. A minute later on way to Montgomery I noticed the hot air. So I get to Montgomery, watching some demo work at the new Tulane Revitalization housing projects, just got in truck to leave and very sluggish to turn over but fried up. Heard a click/thump in dash and air is now ice cold on driver side again. Going to check my battery and alternator. Think the trouble cranking caused the AC issues?

Replacing it is an option but you can also reset it to correct the issue. There is a sequence you need to go through to reset it, I will see if I can find it. This post is protected by copyright.
