The Stovebolt Site Forums The Shop Area General Truck Talk Is there a way to test the wiper motor?

I tested my wiper motor before I had the truck together. I took a funnel, taped a small vacuum hose to the end, turned on the vacuum cleaner and stuck the mouth of the funnel on the metal tube that the attachments go on. The vacuum keeps everything in place. I was able to try all the different functions of the unit.
