for some reason it does not wash my window anymore The high pressure tank and pump is working fine though. I checked the power, no 12V but constant 4.36v goes to the motor... is it weird or what ? anyway I'll have more time tomorrow but anybody had a same problem before ? Once I had a pump replaced and that was oke, I know it was wrong becauise the 12V was there when I pulled a switch, and there was no sound. I pulled the pump out give it a direct 12V - nothing. Bought a new one installed plugged the wires and done- less then 5 minutes it was working again, only to find out my tank was leaking... That was a little more exitment to change but had it done and was good again. But that was an easy fix, I know what was wrong... now it is different... the 4.36V gives me a headache... why isn't 12V and why 4.36 ? what is that ? Fuse is oke, I did not locate the relay yet, maybe that is shot... have a nice weekend everybody, take your 8 series out and just go... enjoy the life...
