My clock in my 85 300sd would run only when warm. I did a search and found info on replacing the capacitors, which I did. Now the clock wont work. I looked at the motor in it while it had power, and the only thing it does is act like it wants to turn, but doesn't quite go all the way. It moves just a little bit, but then back the other way. I let it sit for ten minutes, and the needle never moved forward.

Any ideas? I checked all the connections on the back. Anyone have one they want to sell?
