W123 sunroof Closes, won't Open

My '84 300Ds sunroof no longer opens. I started taking it apart and realized that the motor doesn't make noise when I try to open it. However, when I open it manually, the motor will close it fine.

I pulled and tested the switch, but I have very little knowledge of electricity, so my test could have been bogus.

I suppose I should test for current at the plug for the motor. If I get none in the Open position on the switch, and some it the Close position, should I just start with a new switch?

I have to clean and lube the rails anyway since it doesn't move easily by hand. I cleaned and lubed the cable. I suppose if I'm going to be a good boy, I should clean the tube too....
