I have a 1985 ford f250 6.9. I have had a series of problem's with this truck. I have fixed almost all of them. I just have a this one problem left the windshield wipers won't stop in less I unplug the motor or the switch and or shut the ignition off. The wipers won't shut off. However I have changed the motor out and the switch and it has not changed the problem. I'm about to give up on it and try tho pawn it off on some young kid that doesn't ive two craps about these issuesuand is judt wanting a truck. On the other hand I really love this truck and I dont want to give upbon it quite just yet im just getting so upset and frustrated with this pile of jinck that I'm thinking f getting rid of it its not worth me getting angry at an stupid truck all of the time. So just in recap my windshield wipers dont shut off and ive changed bothe the awitch and the motor and im running out of ideas please help.

First if it's a two speed wiper check the ground on left front fender and ground to wiper motor, meaning if you see ametal strap to one of the bolts make sure that makes contact with motor. If it's interval type meaning it can wipe occasionally that board may be bad and check ground on fender and then under dash on lh side. It goes to wiper switch on those type. Also check battery to body ground there should be one there and connected.
