Three problems related to windshield wiper/washer switch have been reported for the 1996 Ford Ranger. The most recently reported issues are listed below.
While driving windshield wiper and washer comes on by themselves. Has to play with switch to turn off. This happens intermittently. Dealer contacted. Please add VIN.
Windshield wipers and washer operate unpredictably while the switch is in the off position. This is very dangeous since the windshield gets smeared when dirty, causing loss of visibility. Dealer says problem is in switch. Obviously this is a problem accoss the Ford line up, since my son had the same problem with his 1997 f-150 and the problem was present on a rented 1999 windstar. In addition there are numerous complaints on this site. I think it is recall time.
While driving windshield wipers inadvertently come on, and sometimes don't come on at all.
