I am in process of trying to fix a heater control problem on my 73 450SL. The
mechanical flap inside the heater box that regulates/directs the drive's side
floor air/heat does not full close. Driving around with hot air blowing on your
foot in the summer is not fun.
I have the factory manual but interestingly enough it does not have any
information on how to remove, repair or replace the heater box/system. I
believe the dash board needs to be removed, which I am in the process of doing.
The manual states you need to remove the inside rear-view mirror, and then the
interior trim around the windshield.
Can any of you give me advice on how to:
1) remove the rear-view mirror
2) remove the interior trim around the windshield
The rest of the dash removal seem to be going well.
I plan on re-using all these pieces so I would like to know a way to remove
them in one without damaging them in any way.
Please reply at firstname.lastname@example.org
Thanks in advance for your help,
I agree, it sounds like it's at least more than a flap and may not be
the flap at all. With a flap stuck or something wrong with the flap
control system, you get air in the wrong places. However, that would
never give you hot air when the system is set to cool.
