ea81turbo Posted March 4, 2020 Share Posted March 4, 2020 On my 90 Subaru Dl, the temperature guage and 4wd indicator lights (not super important) don't consistently work, I would have thought they would either work or not work, they sometimes work. The dimmer/dashboard backlight does not work at all. Any solutions?. Dodgy relay? Thanks Quote Link to comment Share on other sites More sharing options...

el_freddo Posted March 4, 2020 Share Posted March 4, 2020 Could be a dodgy earth, or a loose connection behind the instrument cluster. The back lights could be the dimmer wheel not plugged in, faulty or set to the lowest setting (off!). Cheers Bennie Quote Link to comment Share on other sites More sharing options...

Could there be a fuse for the cluster light. Or even a relay that is playing up? Quote Link to comment Share on other sites More sharing options...

Dunno mate, you’d have to look into it. Is the thumb wheel for the cluster illumination lights plugged in? If so, do you have a second one to swap in and try?

Naked Buell Posted March 8, 2020 Share Posted March 8, 2020 (edited) Check your ground connections. You could even run a separate ground to make sure you have a good one. For them all to be having problems, I'm thinking ground, only because I have had that problem before and it was the ground.
