How does a Mercedes Benz blower motor work?
That is the design. The blower motor (A32m1) is powered from circuit 30, which is the unswitched battery voltage, via fuse f25 (30A). I second the above posts.
Why does my blower motor run when the car is off?
Blower Motor runs when car is off! Long story short – it was the blower fan regulator. For future reference, don’t buy a cheap off brand replacement unit, it may be defective.
What to do if your Mercedes Benz fan is stuck?
Not hard to do, just drop the blower motor and replace the regulator. The hardest part is positioning your self under the dash and looking upwards to locate the mounting screws. Hi Paul, just wondering if you found a solution to your stuck fan.
What causes the a / C blower to run uncontrolled?
Mostly (according to this forum) a failed BR causes the a/c blower to run uncontrolled. Btw your WIS a/c circuit diagram is not identical to mine for W208. However the blower motor/regulator part is the same. Still the Regulator?

Why does my blower run when the car is turned off?
When full of debris/leaves/twigs/etc from over the years, it backs up and oddly enough, diverts drain water (rain, carwash, etc) just above the passenger footwell…which happens to coincide with where the blower resistor/regulator is located. Hence, water + electric component more often than not = failure. Click to expand…
