Help! Smoke from climate control unit!
Everything was working fine this morning. After work got in car, turned on, display on climate control showed as blank, buttons non responsive. After a couple minutes of driving smoke from the top button area! Smells like burning electronics!! Ideas??

Yeah. I pulled over and turned off the vehicle pronto to cut power to the unit. After letting things cool off for a bit, I turned the vehicle back on to see what would happen. Not only did the smoke not come back, but the unit started working perfectly again! Cold AC, display perfect. Bizarre!

I would replace the unit to be on the safe side. Could it be the light bulb in the unit which blew?

There was a DIY thread done many years ago on here by a member. Perhaps if you search you'll find it.

https://mbworld.org/forums/c36-amg-c...trol-unit.htmlThanks. I read that before but the fix did not work at the end. Even for the original guy that posted the fix. Still worth a try to just remove the unit and tighten the screws....

Anyhow, like PJ said, grab a set of the stereo removal keys and pull that climate control unit out and have a look. Smoke is obviously indicative of a problem. The likely culprit sounds like a loose or exposed wire. Whatever it is, though, find it and get it fixed. If things start burning behind your dash, it can go south quickly.
