Mercedes Benz E300 Blower Motor

Q. I have a 1995 Mercedes Benz E300D. The heater fan seems to have taken on a mind of its own, sometimes working, and sometimes not working. I started thinking there is something wrong with the connections because the lights in the control panel where the A/C buttons are sometimes do not come on when I turn on the headlamps.

Anyway, I took that out of the dashboard, just above the radio, and removed the connectors, and it is sealed. I could not find anything. When I put them back together, the fan was working again, but the next time I started the car, it would not work. I just saw an article from someone who was experiencing a similar problem with an older car.

I did not see the fan behind the console when I removed it. Could you please show me where it is? I would really appreciate it. A mechanic has told me that he has to replace the fan and the control module which he says cost about $450.00 each, plus labor.

He says it is deep down in the engine and he has to remove a lot of things to get to them. I wanted to get on the chat line, but I could not figure out how. Any information you can give me would be appreciated.

A. Before I go replacing parts, I would check this connector first.

If that checks out okay, then I would look at the blower motor. The brushes are probably worn and the brushes, or the motor, needs to be replaced. It is located under the front cowl.
