Radiator Fan Motor

Gary,

I had a problem with my radiator fan motor abt. a year ago. It comes 
out with a bit of difficulty, but the trick on mine was that the 
bolt holding the fan onto the motor had a left hand 
thread.

Once you have the motor out, bend the tags back an pull the inner 
out. Some noise can be caused by the brushes if they are starting to 
go. 

You should be able to replace the brushes, but the main culprit is 
normally the earth connection from the brush holder / stator to the 
body.

I chucked the Bosch bits out and rewired / crimped a thick wire on 
and earthed it properly. The original one on mine cracked and 
come loose from the casing causing the motor to slow down and start warming 
up all the connections. Symptoms was a sudden loss of aircon and a 
steady rise in temperature.

Whatever you do, do it quickly!

Most auto electrical places should be able to redo bearings, brushes etc. to 
get it sorted out. The motor is very basic once it is out of the Audi 
parts holding it toghether. My total cost for repair on the fan motor came to 
about $56.
