3-wire windshield wiper wont park properly
I am experiencing a vexing problem with the park function of my WW motor. After a time consuming search I was lucky to source a used working original 3-wire Bosch motor for my 1750 GTV. Unfortunately, although the wiper does a good and complete sweep of the windshield, it parks about 6 inches too high from the bottom of the windshield. If I manually reset the parked wipers to the bottom of the windshield, the down sweep of the wipers ends up beyond the windshield frame and onto the cowl. I am wondering if the problem can be solved by repositioning the cogged wheel in the motor drive. The only change to the original system is the foot switch has been eliminated entirely from the electrical network. Its only function is to pump wiper fluid.
Has anyone experienced this phenomena? Any suggestions would be much appreciated.
