I can't find anything with the search tool but I need to know if anyone knows how to test the sunroof motor? There appears top be 3 plugs going in, one has power all the time but which pins should have power with the switch and which ones can I put power to to test the motor? It is a 87 560 SEC It has new tracks or angular arms or what ever they are called and supposedly the motor has been rebuilt but I can't even get a sqeak out of it when I hit the switch.
