Check the wiper arm motor under the hood. Sometimes its the fuse, Check the circuit breaker for continuity across the terminals If an open circuit is indicated replace the circuit breaker. Also check between the circuit motor and the ground, and check the battery voltage with ignition on (don't start) if it test for voltage good and the motor still don't work its a faulty wiper motor. A used wiper motor will work as well as a new $$$$$$ one.Denton auto salvage 785-437-2223 test all their parts for working condition before shipping and have a 30 day return on them
there are plastic bushings on the end of the wiper arms ...called wiper transmission...most places will tell you they dont sell them...keep looking cause they do.....they only snap in and then press on the arms
May want to look at replacing the wiper circuit board.It is located on the firewall adjacent to the wiper motor and has a some what square black cover with 3 torx screws and wireing harness pluged into the side.We had a truck that every time you washed it the wipers would stay on until it dryed out.You can try removing it and spaying it down with contact cleaner just watch the brease on the two contact tips.Well hope this helps.
We had the same problem and sometimes they wouldn't turn off. The intermittent wipers were random. We replaced the wiper motor. Be sure to get the motor with two balls on the wiper shaft (one for each wiper arm). If you can't find it, you'll have to change the part out on the new motor. Keep the wiper arms in the same location on removal, or it will jam and you'll have to start over.
