HVAC/Climate Control button repair - ZR-1 Net Registry Forums

8cam · 07-09-2014

My climate control buttons had serious issues. They only worked about 1 in 20 times, and sometimes not at all. That's a big problem in the summer in the south! I used this thread from corvetteforum as a reference and this really was an easy fix that took me about 1.5 hours being very careful. Definitely a 1-beer job.

Climate Control Button Repair

I figured I would post this as a reference and add a few pictures of the process.

Anyone else get rich doing this job? I found $2.26! This was under the shift console, evidently someone lost a bunch of change putting it in the cup holders. Funny thing is, this solved a shifter rattle I was worried about. LOL

When you remove the console lid, pull the shift console back and remove the trim panel, this is what you see. The screw on the right is hidden by the dash pad, but you can push it to the side enough to get that screw out.

Pull the CC unit out and remove the screws holding it together. The only part that caused me a problem was one of the side brackets interfered with getting a screw out. A little dremel work and that wasn't a problem any more, and the unit is open.

This is what you're cleaning. The little round Klingon symbols...targets, whatever. I used a pencil eraser and they cleaned up a lot. Then a cotton swab dipped in isopropyl alcohol to finish it off. I also cleaned the contact pins inside the rubber liner.

Reassembly and everything worked perfectly. All the buttons work like they are new again, fixed a HUGE source of frustration for me. Love it. It's the little things that make me happy.

Superb

Thanks

Thanks! It's funny how the CD/radio head is basically the same design and yet I don't see any threads about those buttons failing, just the CC unit. Those Klingon symbols on my circuit board were brown, but cleaned up considerably with the eraser. Wonder what it is about that circuit board that invites dirt?

In any case, this was the job that made me smile the most. One of the easiest things I've done on the car, but what a difference it makes driving around here in Atlanta. Major annoyance, gone.

Yeah I gotta do that when I take the console apart again to install my 95 Sport Seat wiring harness. I had it all apart once - but discovered I didn't have the whole harness so put it back. I have a buddy coming to help next time I do this - so will feel better about disassembly of the whole thing...

Nice write up. I've done it many times, I think every C4 I've owned had this issue at some time.

Just cleaned the pads as you suggest with a pencil eraser and a cotton swab dipped in isopropyl alcohol on my 95'. The Off and Auto as well as the Temperature toggle was not functioning. Now ALL work perfectly

Great write up with excellent photos
