99 Altima, running lights stuck on

If there's smoke at the switch be VERY VERY careful. Any current flow high
enough to smoke something should blow a fuse way before there's smoke. The first
thing I would do is go through every fuse (and they aren't all on the fuse block --
you'll need access to a service manual) and make sure some idiot has installed
a larger fuse somewhere.

Your problem with failure to cancel was undoubtedly mechanical. It worked OK
after a right turn, and the differences are mechanical.

Well, it actually *was* cancelling after left turns, ie the lever was
returning to the neutral position, but there was still an electrical
connection happening that was causing the signals to blink at a higher rate
than normal. Maybe the slider inside was not quite returning to the off
position even though the lever had returned.

Anyway, I found the problem this time, one of the contacts that the
headlight slider runs over was making contact with another one that was
below it, partially but not totally insulated by some plastic... Last time
I had the thing apart I bent the edges of all the contacts down to try to
smooth out the switch, and I must have brought those two contacts too close
together. I separated them as well as I could tonight, and it seems fine..
if it continues to be an issue I'll just replace the switch; I'm just glad
the problem was there and not buried in the wiring somewhere!

Thanks for your reply!

PS, I will take a look at the fuses, because that was my thought also, it
should have blown a fuse if it was getting that hot... I'd much rather a
blown fuse than a melted dash...
