    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.

No heater blower

The first thing I would try is checking the fuse. If no joy it could be your fan that is dead. Do you get any converting heat when driving?

Heater does not heat, AC and fan work fine

Is the engine getting to operating temp? If the t-stat is stuck open, engine will not heat up and neither will the heater, gets lukewarm. Or is it a door problem in the HVAC plenum? Go to for solutions.

My AC/Heater fan isn't blowing but I can tell the heat and AC are working. How in depth is it to replace the fan/blower motor? Does it require taking half the dash apart like the heater core did? Or is it...

dear friend you are right you to remove basicly the complete dash to get to it,i think you must look at al the other things before attempting to remove the fan

Low heat coming from heater

heater core may be clogged. disconnect the hoses. CUT THEM OFF THE HEATER CORE!!!! If you pull them you may damage the solder joints at the tubes causing a leak. Them connect a garden hose and flush one way then another till water runs clear.

Replacing AC/heating fan -94 MB 300 TDT

The heater fan is located under the plastic panel at the bottom of the windscreen. To change it start off by lifting the bonnet until it's completely vertical (lift it open then press the "Tabs" on the bonnet hinges), next pull off the rubber seal that runs across the bulkhead. Undo the x head screws that secure the plastic panel, there are also 2 white plastic clips which just pullout towards the engine (they may have aleady been lost if the cars ever had a new wiper motor fitted). Once the the plasic panel is out of the way, remove the wiper mechanism and below it you will see a curved black plasic panel. The heater motor is below that. It's held by 3X 7mm bolts on the left side. Good luck!
