Question about 1985 Mercedes-Benz 300
When I swich the heating ON, the blower is not working, while, if I turn the A/C ON, it is working.
Hello, This system has a few components that can cause this. You may have a bad temp regulator box, located behind the glove box, or a bad temp sensor, at center of the dash, or a bad pushbutton unit, (climate control panel}
If you pull out your glove box, make sure that the foam hose that connects your temp sensor to the hard black tube is connected. This provides airflow across the sensor so it can work properly.
If you find this information to be correct would you please enter a "fixya" rating.
