has anyone tried to source the power transistor?it looks to me like the transistor could be replaced but i dont have a # or make.im thinking just solder in a new transistor rather than risk a used replacement and new are quite pricy

WE really need a full set of schematics for our MB's. I asked many about one for our glow plug relay setup and never came up with one.

MB electronic components are insanely priced. Look at the fuse link price! All that for a strip of metal.

i agree a lot of the stuff on these cars is fairly simple tech.the blower regulator looks like a simple PWM deal.the button box inside the car sending out PWM signal switching a mosfet transistor connected to the ground side of the motor.
