So, my '91 300E runs nicely once again.  BUT...
First, no heat.  All the switches on the heater panel seem to work;
fan switches do their thing, center buttons and defrost switch seem
okay, and rotator temperature control engages air-conditioner.  But

what du you think of mercedes to go all green?
