I have a 2003 Impala with dual climate control. The passenger side blows hot air regardless of the temp setting. The driver side is fine. I replaced one of the relays (the middle 5-pin one) thinking that it may be the problem. I found that a fuse was blown. I replaced the fuse and it instantly popped. I am looking for the wiring diagram but cannot find it. None of the parts houses have them and it will take up to 5 weeks to get a copy of the book here. I understand that the slides (controls) are a printed circuit board and I would have to replace the whole thing if that is the problem. How can I be 100% that is what it is. Where the R/S harness connects to the back of the board, is there a certain voltage to look for? Are there any particular troubleshooting steps to follow? The part at my dealership is $290.00. I just want to be sure that is the problem before I continue to change stuff out and spend a lot of money. ANY help would be greatly appreciated. Thanks

You've probably already considered this, but you might check a local "you-pull-it" auto parts place and see what a used part might cost. Obviously there's no guarantee on used parts, but when I had a similar problem with my '89 Toyota I think the used HVAC controller costs $40, while the new part went for $400. (I still ended up buying the new part eventually, but at least by that point I was able to install it in record time!)

Almuerzo, sounds to me like either your air actuator on the passenger side is fried or the vent air arm off the actuator is sticking causing the fuse to blow or you have a short to ground.
Did you find the problem?

Yeah. Kind of. We traded the car in for a new one. I was not able to pinpoint the problem but it's over now.
Thanks for your respnse.

So did you stick with an Impala, or go with something else?

All I ask is if/when you have problems with it, share them over on the Camry boards!

I have the above vehicle that is giving me some fits. Just a couple of weeks ago the A/C started blowing luke warm. I figured low on freon so I added some and still no cold air. After putting in the freon I noticed the next day that when I accelerated the a/c almost quit blowing and that it was making a squeaky noise like a belt was wet. Does anyone have any suggestions. I really could use the help. Thanks.
