Hi Chio.
Thanks. A few of the articles I read allready. I know there are alot on the forum. But some of the links will not open in my browser. (Maybe they are renamed but more likely I have some privacy settings blokking them. I'll find out.)
It's a complicated problem. There are a number of symptoms and it's difficult to pinpoint the separate problems. I think at least one of the watervalves is not operating correctly. But apart from that the plaps from the airducts to the front window do not close. I didn't had the time to check the stepermotor as I had to store my car for the nex 3 month because of some stupid oldtimer regulation in Holland for a few years now.
So I have 3 month time to get to the bottom of the problem. I try to find some info on the control unit behind the sword. I can imaging if the control unit misbehaves the steppermotors will get the wrong info.
These electrical problems start to wear me out.
Thanks again.
Great forum.
