I replaced the Power fuse/relay located under the steering wheel dash. Its a gray canister and only costs $3.00. That seemed to repair the windshield wiper and powerlockes and powerseat. The resone that the ruse/relay went out in the first place was because the power seat switches were touching the frame of the chair. All i did to fix that was to use electrical tape on the frame and around the switch assembly.
because it doesnt work
Your switch on your steering column

The windshield wiper switch is broken which is located on the windshield wiper motor. You need to replace the whole motor to fix this.
system glitch or a short
It may be a bad wiper switch
replace that black box on the wiper motor or sometimes you have to replace the motor itself
Windshield wiper motors have an internal switch that allows a wiper motor to stay running long enough to keep the wipers moving until they reach the "park" position. Once the wiper gets to the park position, the wiper motor is shut off. The internal switch often fails and either the motor will shut off immediately, wherever it is or it will keep running. It sure seems that you need a new wiper motor.

If I had to guess, the windshield wiper switch in the car is bad. It think it's located somewhere among the wire harnesses underneath the dash.
The parking switch inside of the wiper motor is defective. Replace the wiper motor.
