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.
Thanks, Gator241

There is a junction block about 6 inches in front of the battery on the fender, there should be battery voltage on the big wires. The small wire is the starter solenoid. Front the junction block, the power goes to the light switch then to the ignition switch.

I've recently bought a 1983 300D turbo diesel. when I start the car one hot afternoon, and when I went to turn on the A/C, no air blows out of the fans, no matter how I switch the controls on the panel, it...


Check the fuses under the hood. These are the old style exposed ceramic fuses, they have been known to go out from over heating alone. It sounds like the fan is not getting power. If this is the original fan motor, I almost guarantee that the brushes are used up. (Same w/my 300sd) If thats the case and you don't see the dealer fixing it because of the potential cost, a mitsubishi eclipse 1994-1998(from a junkyard) has a small enough diameter of a fan that it fits into the mercedes housing. Be careful and you should have someone of mechanical skill there to help
