Wiper issue

[GMCGoat]

The previous owner installed electric wipers and it rained the other day and wipers stopped returing to cowl location and kept moving up until they were basically going from left to right instead of down to up.

Hope that description makes sense. Any ideas of a fix? To me it seems like wiper arms/or wiper "gear" is stripped.

Check the base of the arms and make sure they were pushed far enough down onto the splines to engage. There is a small flat spring clip that will catchthe groove when they are down. If they are floating above the splines, they will act as you describe and should be easy to pull off the splines stud

I just had to reposition mine because when the truck was restored they did not position them correctly. I found that it was a 2-person job. One person had to release the spring while another pulled the wiper arm off. The person releasing the spring actually sat in the truck and looked through the windshield so they could see what they were doing.
