Climate - Low and medium fan only ('95 S320)
 

My climate control (blower motor) only operates at low and medium (maby not even medium ) speed. If set to auto or high it barely makes medium speed.
I had this fixed a couple of years back at the dealer, but as usual everything done at the dealer breakes after a short time. I do not remember exactly what the problem was that caused this anouying problem.
I would like to takle it myself now and hope someone can point me in the right direction.

I followed the operational check as described at:

and the operational check shows normal. The step 8 shows reading from 8 - 60 volts to the motor according to the settings on the speed. :confused:
Trying to follow the procedures to read out the error codes, I can't get them to come up. It always displays the Operational check readings again. :mad:
