FORD F-250 BODY PROBLEM

1989 Ford F-250 • 15,000 miles

1989 ford f250 p/u. About a year ago windsheild wipers stopped working properly. Intermittent & slow speed do not work and fast speed works slower than normal but only back & forth 3-4 times before stopping altogether. Must turn switch off & back on brfore wipers work again. I've changed motor & switch twice each & voltage regulator with no improvement.
