Okay, I'll give it a shot. I have a 96 caravan se, about 3 months ago
while I was sitting outside having a smoke after dinner, the headlights
turned on by themselves and then after the time out they extinguished.
My van has 188000 miles on it and has not been too much trouble to own
or maintain. I have had switch related problems with the power windows
and the radio, but a careful disassembly and cleaning made everything
work as new. So far I had been lucky. I figured that I would remove the
light switch module and clean up the contacts the following morning. To
make a long story short, might I suggest getting a new switch module
from your friendly local Dodge dealer, that's what I had to do. If you
have tons of patience, and strange shaped fingers and extra luck you
could probably clean it, but it's a lot less trouble to replace the
assembly. Mine was $75.00 American @ the dealer and about a half an hour
to disassemble the dash and install. Apparently the switch will start to
corrode if the wind blows rain on the dash in just the right way. I
could see when I removed the connector the telltale green copper traces
that I assume must have had enough continuity to activate the lights in
the automatic off mode. Anyway, this worked for me and it is as good as
new. Frustration level = 5, cost = $75.00, scaring the heck out of my
mother-in-law when they came on by themselves = Priceless.........My 2
cents........Mr. B
