Just say n2o

<---- This guy is a dumbass. There always has to be one that takes an easy tech tip and f's it up. I got it all apart and soldered all the resistors, plugged it back in and it worked, sweet!!! About 30 seconds later I smelled smoke and the display went out, WTF So I pull it back out, get it back apart, and low and behold I see a large blob of solder up in the corner of the circuit board underneath it a burnt line in the board. I guess in my excitement to get it put back together I missed that I dropped a blob of solder on the board thereby shorting it.

Ouch!:o

did you fix the burnt trace?
does it still work?

Just say n2o

It's boxed up and on it's way to be rebuilt. Hopefully nothing else is fried.

Cool I can't wait to try this!

I tried this method and it didn't work. My backlights still don't work on the AC buttons, however the backlight for the display works. Is there something else I should try to fix the bulbs behind the buttons?

My car goes in to the dealer tomorrow for a new display.
I'll see if they will let me keep the old one to play around with and find a way to repair the button lights.

all of the back lights were out on mine when i sent the unit to mandigital or whatever the ebay guy is.
came back all fixed. same price $45

Just soldered mine. Will test and report findings

The dealership replaced the unit but, I was unable to keep the old as they had to send it back to GM. So I won't be able to tear into it and look at the button lights.

Of course, my HVAC is totally different from all of the others posted. What a surprise.


Still: I soldiered on and soldered all the surface mounted resistors nonetheless.


Success!! Works like new!!

So all I need to get is a soddering iron and some sodder?

Z06ufgrad2002

Yup

ryguy84

Thanks Z06! Z06 do you also know where I could find some info to remove the climate control unit? Ive looked but so far no luck. Also what wattage of a soddering iron should I see a 15 watt and 30 watt or the dual? What kind flux solder do I need theres 2 kinds?

Z06ufgrad2002

There is a good write up here:

Follow these instructions up til the point where the climate control surround is removed. At that point you won't need to go any further.

Then there are just a few screws holding the A/C control unit in and after that you can follow the instructions in this post.

a 15w pencil should be fine, you want rosin core solder, go to radio shack, they will have everything you need.

thanks everyone for the help cant believe it works. But now I got 2 lights out on the panel the off and auto button how do I fix those?

Thanks to those that posted pics. You guys saved me $45. Mine looked like the later pics as well. Tried a Cold Heat iron and touched up the surface mount components only. I have a pretty good idea of which one was really bad since when I hit one end with the iron it slid off the board. Repositioned with pliers and hit it again. I didn't add any more solder. Has been working great all week.

Does anyone have a part # on this piece.
I am curious how much a new Automatic Climate Control unit costs.

RPOZ4Z

they are a couple hundered dollars brand new.

I took mine out and soldered it last week and it works great and I have the satisfaction of fixing it myself. I guess procrastination paid off this time, because I was going to send it off earlier this year, but was too busy. Anyway, just got back from getting new Kumhos MXs' and an alignment, what a difference. Thanks RPOZ4Z for the info. If you're ever in Denver, I owe you a beer
