2002 Chrysler Town and Country light switch problem

I got a 2002 Lxi. Recently it has been acting wierd. When I open the
driver or passenger door the parking, rear and fog lights go on. They
never did that before. It does not have auto lights either. Now when I
open the door and they go on, if I turn the light switch to parking
lights then the fog lights go off but parking light are still on. If I
then pull out the switch for the fog lights then all the lights go off
just like the switch is set to off. If I turn the switch to full lights
then they work fine and if I pull out the fog lamps they turn on. It is
just like the Off and parking light/pull out fog setting is mixed up.
Anyone heard of this problem and any suggestions what to do? I thought
of disconnecting the battery and see if that will reset it. Any
comments to help would be great!

 

I would check all the grounds on the are and the battery. Also a battery
going south can cause problems. In most Chryslers, the light switches are
multiplexed using resistance so if things go off electronically all kinds of
wiered things can happen. A dirty contact can cause problems too.
