Heizung/Klima: Continues heat at window vent.

[Beumers]

Hi Fufi.
I drove around for a while to make sure the water got hot enough. With the intake to the watervalves clambed of, the left vent at the front window got mildly warm. The rest of the vents were all cold. The wheels of the operating unit on the dash all on cold.
So I can drive arond with it without steaming out of the car. Keep in mind that it is allready oktober. I think it's strange. The only explanation I can think of is that the clamb is not completaly shut and lets trough a little bit of water.
No key in Ignition. Blower on Zero. I measured 0.35 Ohm between 1and2(Y/BR/PRP) and no reading between 1and3(Y/BR)
Blower on first position, no reading at all on both 1/2 and 1/3. No Ohm reading.
I'll try and wire pins 1,2and3 as you mentioned to find out if the water flow is stopped by the watervalves.
In the back of my mind I think I already tried this last year. ( Stopped working frustrated.)

Regards Henk.
