Hallo Erich und Marcus.
Yesterday I was able to check for 12 v at pin 1 of the watervalve connector in the car.
Ignitionkey al the way to the right. Control unit on the dashboard switch on auto. No 12 volts.
If I read the electrical manual the right way the 12volt connection goes right trough fuse 33 to the control unit on the dash where it goes via switch auto directly to pin 1 for both the valves. The negative contact goes trough the control unit behind the sword to each valve separately.
It's the same way it is described in the pdf "klimaautomatik". I checked the electrical manual to be sure. (It would be very helpfull if everybody used the same description for the parts and units.)
For now I can rule out das Steuergerät I think. So first I have to find out why there is no 12volts on pin 1. Thanks for pointing that out again Marcus.
Now I have to wait untill I can go back to the car in the storage.
Keep you posted if I can.
Regards Henk.
