Good luck ! You might need to invest in a manual to
help you diagnose the circuits. A good investment in
my opinion. Chris D.


Mine did it when I put my phone charger in the cigar lighter. I found the lighter base was not assembled right and was shorting everytime i pushed it in.

If I were guessing I would look at the cigarette lighter connections.
All electronic stuff is filled with smoke. That's how it all works. When the smoke leaks out you know they are broken and they don't work any more. Sorry Couldn't resist...
What ever you do, don't get a fuse with a capacity for more smoke (i.e. a bigger fuse) you will start to melt wire and of course the smoke will leak out of the wire but that's harder to replace.
I agree with the comments on the cig lighter from all before. Maybe your lighter itself has a short in it. If you are a non-smoker and don't use your lighter socket for anything else, they can get corroded and short out. Maybe that's what blew the fuse in the first place? In any case I'd be checking it before all the other places that CeeDee referred to, it's the easiest one to get at.
