My rear heated screen has stopped working on my 04 90 TD5. All I've done so far is check the fuse which is okay. Do the switches fail or is more likely to be a broken wire in the loom? There is no voltage at any of the terminals on the sreen.
Bit of a late reply but I shuffled the relays around and the rear screen started working. I swapped the relays back and it's still working so it looks like a bad connection to the relay! Thanks for the pointer Tony.
