Hello, I have a 2002 F-250.Power Stroke. I left for work one day and turned on the wiper switch, and nothing happened. The washers won't wash either now. I have never had a minutes worth of trouble with them before. All fuses check out good. I switched relays around, without any success. Everything else works fine. I'm not sure if it maybe the wiper motor, or a bad multifunction switch. I only have 37,000 miles on it. Its always garaged and used very little. Has anyone else had a problem like this? Thanks for your help! beatlebailey50
