Wipers do not park correctly
My 2000 Windstar wipers do not park correctly during intermittent operation. They will stop at random positions and then they stop altogether. Does the park feature come from the wiper motor itself? Will a new wiper motor correct this issue or do I need some other repair. Thanks for the help.
And while I know my Windstar is not a truck, in Texas, it was registered as a truck. Here in Dixie, it just a van.

I think the wipers work the same as my old Lincoln Mark VIII: Found this in their forum. Worth a try.
"Usually just a mechanical function. Take off the intake grills at the bottom of the windshield. That will give you access to the linkage. the first linkage connection away from the where it bolts onto the motor is where the park function comes from. In "wipe" operation the motor turns one direction, and in "park" it turns the other direction. That 1st joint is cammed to change the "moment" of the linkage. The usual problem is that the joint is dry and needs to be lubed. Too heavy of grease is not the answer. (it gets too stiff to work in the winter) Use light machine oil or spray Teflon or silicone).
The only other problem is that the motor has lost the ability to reverse direction."

Thanks for your reply. These wipers seem not to reverse when they park. The motor just stops when at the correct position. During intermittent operation, the wipers stop at random positions. I'm not sure from where the stop position is controlled, motor or some external device. Once I get up some courage, I'll remove the wiper motor and take it apart and see if it doesn't just need a good clean-up ans some new lube. The older systems had cams and switches in the wiper motor transmission. Not sure about mine. We'll see.
Thanks again.

Most wiper motors have a cam switch inside them. That's how they know where they are and where "park" is. The motor has power all the time from the keyswitch, and another power wire from the wiper switch. When the wiper switch is turned off, the power from the keyswitch carries it through till the cam switch stops it inside the motor.
