If the '96 is the same as the '99, then be ready to shell out a few
bucks. The assembly is actually a line of LEDs on a printed circuit
board. The printed circuit gets nasty and corroded from moisture,
heat, cold, etc... I have had very little luck repairing the boards or
connections on the board. It is easy to remove from the vehicle and
then easy to take apart. Check it out before you buy a new one.
The dealer will get nearly $70 for one. Ebay has them aftermarket for
about $25/30 the last time I checked.
