Hey guys:

My brother's 86 300SDL as suddenly aquired a climate control problem. No floor heat, only windshield, and the fan doesn't change speed when you push the high or low buttons.

Is this a vacuum problem, a pushbutton control unit problem, or (ouch) a servo unit problem?

Onset shortly after the turbo was replaced (dealer, plugged trap oxidizer). Vacuum lines intact, but I've not yet checked for leaks.

All help greatly appreciated!

Peter
