Andyreet Posted March 30, 2018 Report Share Posted March 30, 2018 My Dashboard backlight is not illuminating correctly, it’s usually on when I start the car and turn my lights on but as soon as I move it turns off, then doesn’t come back on until I hit over 60mph at which point it quickly flashes on and goes back off as soon as I stop accelerating. All the gauges work absolutely fine the whole time and i’ve checked all of my lights which work. I’ve only recently had a new alternator too. Any ideas?

mk2 Posted March 30, 2018 Report Share Posted March 30, 2018 could be the dimmer switch thing next to the lights switch. loose wire? Quote Link to comment Share on other sites More sharing options...
Rich Posted March 30, 2018 Report Share Posted March 30, 2018 that's what i would suggest looking at first. pull it out and just bridge the two wires. Quote Link to comment Share on other sites More sharing options...
Andyreet Posted April 10, 2018 Author Report Share Posted April 10, 2018 I’ve pulled out the dimmer switch and ordered another second hand one but still the same problem! Quote Link to comment Share on other sites More sharing options...

Sorry but what do you mean bridge the two wires? There’s a fair few wires going into the back of the light switch Quote Link to comment Share on other sites More sharing options...

mk2 Posted April 10, 2018 Report Share Posted April 10, 2018 do all the dash/switch lights do it, or just the instrument cluster? Quote Link to comment Share on other sites More sharing options...

mk2 Posted April 12, 2018 Report Share Posted April 12, 2018 ok, then it's definitely something to do with supply to or from dimmer switch. basically the supply to the entire circuit affected. try what rich says and find the wires which supply the entire illumination system.

Andyreet Posted June 8, 2018 Author Report Share Posted June 8, 2018 Solved! Literally took all the connections off the battery etc, cleaned them all down and it magically all came back on! Quote Link to comment Share on other sites More sharing options...
mk2 Posted June 9, 2018 Report Share Posted June 9, 2018 unlikely, as the main feed splits many ways. me thinks lucky coincidence. Quote Link to comment Share on other sites More sharing options...
