Three problems related to windshield wiper/washer switch have been reported for the 1996 Plymouth Voyager. The most recently reported issues are listed below.
Noise emanating from the rear drums during stopping at times, inspected the brake system. Pads/shoes were worn out prematurely specifically the rear drum pad which were worn to the rivets at 35k. Because the rear brakes worn fast, the front rotors took over the majority of braking and subsequently warped the rotors. Since replacement, the noise has not occured again. Also windshield wipers began operating by themselves when driving. They would come on and wipe the windshield 1-3 times without ever touching the control switch. Control switch replaced and problem went away, started again sporadically.
Windshield wipers would come on by themselves, dealer replaced the wipers cowl molding and replaced the multi-switch.
Windshield wiper switch failed, causing wipers to suddenly come on while driving.
