my blower motor on my 300SD just all the sudden quit working after it was working perfectly fine. I hit a speedbump, and it quit working. I checked the fuse, it was fine. Next day, started it up, blower motor worked for about 30 seconds, and then quit. I have power to the fuse, and no power to the blower. I can hear and feel the relays clicking, and the acc unit appears to be working because when i turn it to heat i can feel heat trickling out of the vents when i'm going over 60 or so. Any ideas?? thanks,
Ryan

A bit of guesswork here.

No power to the motor (measured at the motor) might be blower control switch(es)

Power to the motor but no run might be bad brushes.

found the problem, thanks guys

... waiting for the other shoe to drop....

What was the problem? I'm curious, and it could be a good source for the database here.

haha, sorry about that one. The problem turned out to be in my aftermarket fuse holder than i made. I ruled it out since i could hear the a/c compressor clicking on and off, but it turns out the blower motor hot wire wasn't making a good connection, and that the a/c clutch was. Wish i would have known that before i tore apart my entire center console and lower dash.....oh well live and learn.
