We're in the dark!!

Hi all,

We own a 2011 Thor Windsport 31g and we're having issues with the speedometer backlighting. It won't light up anymore. We've tried the dimming wheel and the lights ARE on and nothing.

Does anyone have any insight into this? Maybe a fuse I should be checking or something. A mechanic recently added some wiring into our 12v lighter socket so I'm not sure if that might be a cause or not. We're on the road again now though so he can't look at it.

Any help would be greatly appreciated.

Can you get a test light back there to see if you have current to the light switch, and if so, then the light socket? I don't have a Windsport but the electrical principle is the same. If you have current to the switch then the light is probably faulty unless there is an in-line fuse between the two. If you don't have power at the switch then you've got to trace back to a fuse or circuit breaker.


Good luck!

If they've got headlights: there's juice coming out the other side of the switch...
Could it be that the switch portion which takes care of the dimming feature is bad?

There's no mention of the other dash lights, just the speedo? Do the other lights work?
