1999 C280 Heater Problem

mlupt · 09-23-2008, 10:00 AM

The drain ports at the front of the windshield on my car got blocked. So after a big rain, water entered the passenger side of the car. Vaccumed up the water. Someone at a local repair shop took compressed air and cleaned the ports and no more water.

However, the heater/AC blower will not run now. When I attempt to turn on the unit, I hear the usual flap, but air does not blow.

Could anyone tell me what may be wrong. Is this something I could fix myself and save money by not going to the Benz dealer?

Thanks!

Have you tried the self diagnostic test with the CCU? Also check your fuses.
If you don't know how to do the check I will send instruction on how to do the test. It could be several things but for now I would not jump to conclusions...ie resistor block, obstruction in squirrel fan, bad blower motor, fuse (s), loose or broken wire, you get the idea.
