[W126 Coupe] Heater Blower Motor

[Mike R.]

Bellamy,

The SEC has a 30 amp blower fuse in a little 2" plastic box just in front of
the brake booster on the back of the forward firewall. Check that first.

 

Also, I've a push button assembly go bad and the blower motor went
intermittent because of broken solder joints inside the button assembly. Let
me know if that's the problem and we'll go over what to look for in there.

 

Later,

Mike R.

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..........
