c5 rear window de-mister.

[dowen]

Well its the time of year just when I need the rear window de-misted, and or course it dont work!
So Ive done all checks, stripped down and removed rear break light cover, and have got 14v+ to terminal block (c5 2006 est). So fuse and relay OK.
I cant see any breaks in window element, but the actual connection where it goes into rear screen are covered in a plastic cover, does this come off?
Ide like to check under if I can! Theres .06amp flowing with switch on and engine running. not enough !!
Does any one know resistance of element?
Also Im only getting 8v on the yellow wire that controls rear window solinoid, (this is a seperate circuit from heater) so the window solinoid wont actuate!
Haas anyone come up with this problem?
Cheers Dave.

Have you checked the 'earthy' end of the demister for volts, shouldn't be any if there are check the connection. The window relay problem is probably due to corrosion round the switch, a very common fault, mine has never worked but I have never felt the need to use it.
