C 230 k - (w202) HEATER BLOWER not working :(

[dan653]

Hi,

can anyone help ?

i have a c230k 1995 - N-reg. And the heater blower isn't working.

The air temparature still works fine, and it is very warm when the engine has been running, however the blower its self doesn't work. This causes problems in the morning with de-misting etc...

Apart from the motor, are there any other possible causes that i could investigate (that may be cheaper to fix).

If so, how and where do i find these bits to check.

Thanks
dan

Could be any one of a few things, blown fuse in the main fusebox under the bonnet, worn out blower motor brushes, burnt out blower motor regulator or seized motor.This link will show you how to get the blower motor and regulator out to check it ; http://202tech.mkosonen.com/howto/blower.html.
It could even be a faulty blower speed control unit on the dashpanel, just a matter of going through it methodically and checking where you have power.

As george above,you really need a volt meter to check where the 12volt stops,saves alot of work.

Just to let you know it was the bushes, all worn down.

Now cleaned up and replaced and running well

Thanks for your help
