One problem related to tail light switch has been reported for the 2003 Chrysler Town & Country. The most recently reported issues are listed below.
Driver's tail lens fell off while driving at 65 mph on the way to lubbock TX. It is not hit or damaged in any shape or form. The glue simply failed holding lens onto tail light assembly. This needs to be screwed or recalled for improper installation. Dealer wants approximately $320. For part and does not include installation. I googled this issue and there are several complaints on the web. This is a hazard while driving at night as it blinds drivers behind me and most likely could get a ticket from police departments.
