Ok, can somebody tell me how does the heater of the w124 works?
I know that the monovalve is connected directly to the 12V and works with ground inpulses! So, if no ground than you have full heat (valve opened), with ground you have no heat (valve closed)! My question is how do you have worm temps??
Another question, the w201 heater isn't electronicaly operated like the w124, it's vacum operated, it seems like an easier setup, hould it be possible to fit a similar setup in the w124?
Note: forget the AC!!
With kind regards,
