My intermittant wipers have worked great until today. I have lost any intermittant feature. If I just turn them on witout squirting any fluid they run but when I shut them off they will stop anywhere in the stroke. They do not go back to home.

If I squirt fluid they start, again no intermittant features, but they will not stop at all until I shut the truck off.

I have never had a problem before, except replacing the motor a couple of times, so I have never really read up to much on these. Is it a motor issue, or is there a module in there that has stopped working.

Hopefully I will have time tonight to have a look at them but any insight would be appreciated. Thanks.

 

There is a "park" feature built into the motor/gearbox. If that switch fails, they won't return and stop.
