Money Pit Driver

Wife has our "money pit" on the road. So I just checked my 124 CD Repair Manual. You're right, only cooled air thru center vents. I always wanted heated air thru center vents. I guess MB doesn't care about sending warm air to rear passengers. Fortunately, my golden retriever doesn't mind.

Note to mbzman: It's the button with both solid white arrows closest to temp dial. And vac hose goes to reservoir in rf fender well before going into cabin.
