Jules,
Nice video! Thanks for posting. You helped me out with my motor not working correctly. My ground problem was the type of screw used to secure the tab to the frame. You suggested a separate ground and it worked fine. The dash frame on my car was original, not repainted. I had what appeared to be a stainless steel screw and the motor didn't work properly. I put in a different screw and it worked fine. As always, thanks for all you do and for sharing info!!
