While parked at the beach yesterday in 98 degree temp I guess the grease in this switch got hot, melted and short circuited the contacts again. Thanks to information learned on this site, a phillips screwdriver and a Q-tip, all is well again. Nothing like the wipers coming on every few seconds on a dry windshield with small sand particles trying to scratch the glass. This time I removed all grease. One other time I just cleaned most of the grease off. Total time of repair five min.
