Default A/c-heat Problem

I think I saw a post about this same problem before but I can't find it through a seach.
I'm get cold air on the passenger side and hot air on the drivers side. Tried checking codes but nothing there no codes. Any ideas??

Probably my post. What is the temp set too? Basically, which side is correct (if any)? Could be an actuator or, as mine turned out to be, the HVAC control unit.

passenger side is correct. I can turn drivers side as cold as it gets and it still blows hot. Just started all at once no problem until today.

Probably the air temp valve actuator for the L/H side.

Thanks to a previous postr by Jr_Vette my problem is solved. All I had to do is disconnect the battery and reconnect after 60 seconds. The actuator reindexed itself and all is working properly. I wanted to quote his post but couldn't figure out how to get it done.
Thank You Jr_Vette!!

Default Me too!

I'm having the same problem - and just posted this problem a few days ago in the General section. My problem is the passenger side is always blowing cold A/C (driver's side is correctly operated by the HVAC unit). I'm out of town, but definately going to try this as soon as I get home!

That's the exact problem I had. Definitely try the battery thing first. Didn't help me of course...

I had the same problem and the dealer indicated a leaking compressor at the compressor half. I had the system recharged and it only lasted 5-6 weeks. Replaced the compressor, idler, and belts. $1500 later, hope it lasts as long as the lifetime compressor warranty. Seems to work well now.
