Parting out my '78 300D. It had a re manufactured servo unit and A/C Amplifier installed in 2005 from previous owner also a friend of mine. (see copy of receipt). Cost my poor friend over a grand to have the work done ($835 just for the reman unit).
Will try to post pictures of actual part soon...




From my personal experience, the auto climate control's "brain" and vacuum system seemed to function as normal. The system would adjust fan speed, based on push-button selection, and seemed to adjust fan speed based on engine temperature as well (if calling for heat, it would wait till engine warmed up).

The A/C compressor was bad so unfortunately could never test A/C functionality.

All the air dampers function like they should, switching from floor vents, to upper vents, defog, etc.

I'll also mention that I rebuilt the blower fan motor with new brushes and this is also in good working condition.

Open to all offers!

Inquiries welcome, many other parts available; as stated, I'm conducting a part out of my vehicle. Thank you.

I wish icould unload you of a few parts from yours for my '78. ain't got no cash doe...
