Lude Generation

My rear demister isnt working. I have the light coming on in the switch, so assume its not a fuse or the switch itself. Can anyone suggest if there is anything I should be checking first, or is it simply a matter of checking for voltage at the rear window and then working back from there?

is there a plug that connect to the rear screen ?

I think there's a relay in the footwell fusebox.

Here's the 4th gen' fusebox. I don't know whether 5th gens are the same.

Check the windscreen it self
And the 2side main connectors
If not
U have a broken connection some where the lines on the rear screen it self
U can buy the repair conductor paint from halfords or may be your local accesory shop
Re make the connection
And bingo

Put some hot water in a pan put it on your rear shelf
Let it mist up move pan after a while
Switch on rear demister and u see if it works!

check the fuse and relay the light will come on if there is power at the switch nothing more

My money's very definitely on the relay, which is in the footwell fuse box.

*edit - I completely failed to notice this was for a 5th gen... Doh!

Thanks for the advice everyone. The fuses looked ok, and the relay was clicking as the switch was operated, but I have swapped them over from my old lude. Will try it later when the sun goes down and the windows mist up. If still not working then its a voltmeter to the rear window connections.

The connector unglued itself from the rear window of the Civ. I tried re-bonding it & using sliver HRW repair paint, but to no avail.

Might be that, or a break in the elephant.
