[W126 Coupe] Heater Blower Motor

[Hein]

Bellamy,
Don't know why, but I had the same problem a few years back. I ended up changing the porcupine and the motor started working again.

While doing this I did fool around with all the wires in the passenger footwell, so it may have been a bad connection somewhere.

I can't remember what I read and where, but I replaced the porcupine because of some recommendation that I picked up somewhere. It worked. Coincidence?

  All;

  I have another electrical problem looking for an answer.

  The blower stopped running, to the best of my knowledge while I was driving.  There is no power at the motor now.  The climate control system has had no problems up until that point.  

  The motor never made any rude noises, ran silently and smoothly

  The fuse is OK

  The fan (motor) runs fine (put 12v to the motor),

  The blower control unit - fan speed controller is OK (switched with a known good unit) 

  Does anybody have experience with the push button controls failing or the climate control unit itself?  What other components have control over the motor power supply?  Appreciate any ideas..........
