my climate control is going berserk on my 300E! whenever my heat is off one of the relays in my dash keeps clicking every time I hit a bump or accelerate. I have traced the problem to the climate control switches. when I hold down the off switch the clicking stops.
anyway, my question is, I know that most switches in my car can be taken apart and cleaned. can I take apart the switches in my climate control switchboard??????...or, do I have to buy a new one?
your comments will be greatly appreciated!
thanks!

You may try to take the bottom off of the box and solder the connections. IF this doesn't work, you can get a reman unit from us in the fast lane above.
