wiper motor testing
Mine didn't work I took it apart and the points were dirty. They are pretty simple , When reassembling it you'll install six new rivets three from the back and three from the front. The brushes lock back themselves you just have to push them after the commentator is in place. Make sure the armature is snap ringed in place then put the halves together. I have a bunch of 2 speed motors but mine had a 5/16 18 nut holding the linkage all the others I have are 1/4 20. I have more pictures of them apart if needed
