rear heated windscreen does not work

**audisingh** · 23-12-2009,12:35 PM

i have checked the fuses and they are all intact.

when i press the heated windscreen button, it comes on and then goes off two seconds later.

i have recently wired up the heated seats wiring loom from kufatec.

anybody have any ideas?

hi, thats a thought... i will check that. Do you know which column block the heated windscreen wire belongs to behind the climate control unit?

cheers

no idea on what wire is for what just a thought seen as tho u have added wires like i did when i did it on my old b6 u could have knocked 1 out

checked all the connections behind the climate control. No Luck. I will try the old climate control unit to rule out the wiring maybe.

just tried the old climate control unit and the rear heated windscreen works. So that rules out the wiring. Could it be the climate control unit?

I was about to ask if you had changed the climate unit due to wearing buttons/heated switches needed and you've answered it!

It is the wiring I'm afraid (or lack of it) Nov 2004 and on units don't have the relay for the rear window in them, the design was changed for some reason. You need to wire a relay in behind it. I have the guide (from another forum member), if you PM me your e-mail address I can send the guide to you. (Can't upload here as the file's too big!
