I have a 1994 S500, and bought it a few months ago. I have a question about the blower speed for the climate control.
The heater and A/C functions as it should, with the exception of blower speed. It seems that the blower seems to run at one speed only, a med-lo speed. The unit EVENTUALLY cools down or heats up the car, and the airflow moves to the appropriate spots when different control buttons are pushed, but there is no High speed.
Is there a fuse or relay that is dedicated to the high-speed blower function??
Or any other ideas on what might be the cause/cure of this??
