You’re wrong about the automatic climate control
I used to work on those cars, and the US spec C240s all had a control panel with an auto button
Do you have a gray market . . . or Canadian . . . car?
The glovebox is in the passenger footwell. Drop it and see if there’s a bunch of leaves in there
I recall that there were numerous technical service bulletins pertaining to the blower motor for your car. There were updated blower motors and blower control modules. I’m going to guess you don’t have the latest and greatest
Another heads up . . . your car was well known for having problems with the ac “stepper motors” and linkages seizing up and breaking. In some cases, when they would act up, the case would crack. Have you been hearing clicking noises from behind the dash?
If the guy messes around with the ac stepper motors, make absolutely sure he knows how to normalize them after the repair. Otherwise, they won’t work correctly. It’s not like an American car. They will NOT figure out their home position on their own.
As for the brakes, I highly recommend sticking with genuine Mercedes-Benz parts, or at least German parts. Make sure the guy drives the car on the freeway. He won’t feel a warped rotor applying the brakes at 30mph.
