A little backgrounds, my W203 C32 AMG charcoal filter stepper motor gear is broken again, so it gives the infamous clicking. Its been already fixed once, so not in the mood to fix it again ( the entire HVAC has to be removed).
So im trying to find out how these stepper motors are controlled, because they are just 3 pinned and all are controlled via the same 3 wire ribbon. I know part of the plastic connector is the coding portion.
Is there anywhere i can read this up (been at google for 2 days, no luck)
I've found that pin 1 is 12v, pin 3 is grd. Pin 2 is control data, is it pmw?
Hope someone can help. Tq
