Car is a W124. The blower motor doesn't seem to be working.

- I've tried selecting all of the different buttons on the climate control unit including changing the temperature wheel from cold to hot.

- I've checked all the fuses (in the fuse box in the engine compartment on the driver's side)

- I've removed the blower motor and noticed that the fans were very stiff when turning by hand. I oiled them up and it still doesn't work.

- I checked the voltage on the blue and red wires that go into the blower motor and it read > 12.xx volts. The strange thing is that it read > 12 whether or not I have the ac/heater selected on/off.

Shouldn't it read 0 if I have it off?

If not, does this mean my blower motor is bad?

- I also heard that it could be a bad contact on the climate control wheel. If this is a possibility, how can I remove the wheel to clean the contacts?

And what do I use to clean it with?

Sorry for all the questions, but any advice would be greatly appreciated!

Thanks,
Tygger
