My electric windsheild quit working on a recent trip to NC. It was stuck in the up position. I removed the tupperware to find a wire broken off on the motor sense switch that shuts the motor off when the sheild reachs the end of its travel up or down. I had to remove the white plastic cover to resolder the wire back on. Motor now works in both directions when I maually test but I can's get the cover back on and have it work. It has a strange gear driven cam that needs positioned just right for everything to work properly. Does anyone know a simple way to put this back together? It has some markings that I'm thinking must need lined up or something to sync everything with either the shield up or down. I've tried many combinations and nothing seems to work. Any help would be appreciated.
