Heizung/Klima: Unknown type watervalve

[Beumers]

Hi Erich and Marcus.
To check if there is any current comming out of the connector on the valves I have to measure this in my car which at the moment is put aside for 3 month due to regulations in Holland for Youngtimers. But it's something I have to do I know. It's easy to forget to check if there is 12 v. at the connector. It could mean the control module has some issues. That's why I'm not keen on buying expensive parts if I can't find the real source of the problem. I own this car for over 5 years and looking back on it the electrical system is a disaster. There are so manny issues. It's very hard to see the connention between them but that's my problem.
The pump has to wait before I spend money on it. There is more than enough heat so if there is a little bit less that's fine with me. First things first.
I'll check asap if there is current in the car. If 12v is at the connector can I rule out the Control module? If there isn't any 12 v. what in your opinion is the best next step I take.
Thanks for your input.
Henk.
