Heater fan is not working at all

Solved the issue. My blower was not working at all so I wasn't sure what exactly it was until I removed the blower itself. In my 1998 Mercedes C230 (W202) the blower is located on the passenger’s side just below the dash board.



1. Remove the passenger vent cover located under the passenger dash and to the left next to the center consol.

1.1. There is a plastic Phillips head screw you turn 1/4 counterclockwise and pull out the vent cover.



2. Remove the three Phillip’s screws located at the bottom of the passenger dashboard.



2.1. This will allow you to drop the dashboard cover by pulling down and then out



3. Once in there you'll see the blower motor cover, notice two white plastic tabs. Before you move the tabs be sure to unplug the blower motor wiring harness.



3.1. Move these tabs and pull down and out on the blower motor cover. This is located nearest the outside of the vehicle.



4. Next there will be four Phillip’s screws holding the blower motor in just unscrew them and the blower motor drops out.



At this point if you have power coming into the wiring harness, you can check this with a volt meter than it's your blower motor.



In my case I had the car in storage for 6 months and the motor had stopped moving. I just had to apply some force to get it to spin freely again. I used WD40 to help grease it. And the rest is history.



Hope this helps you out.
