Trying to get power to rear screen on my 1990 90,has not worked for years. Fuse is good,switch is good.
Where is the screen relay? My old book of lies does not even show it on the wireing diagram.

Any know which is the rear window relay? Is it one in the row below fuses or is it hidden somewhere else?

just looked at my old loom and there is a relay after all, it's hidden behind the binnacle.
Hrw and wipers are on a separate harness/ loom which was added to order, mine is all stilll cable tied up as it was when removed and the relay is in this area.

Had a look today and found the HRW relay. Tests show no power getting to it, all though there is power going through the switch.Did not find a box with glass fuse's.
Have yet to check ignition feed.
