Smile 1989 300E Power Seat Problem.

I have a 1989 300E in very good shape. The passenger front seat is in the forward position and will not move back. All other movements work. How can I test the switch to see if it is the problem? Is there a schematic of the switch available? The forward position elicits a grunt but the reverse does not. Does the same motor move the seat forward and backward? Is it a reversing polarity system?

I have tested the leads to the 2 large posts and have power. With the switch in the reverse position which post on the switch should be 12V+ and which post should be ground?

Thank you for any help anyone can provide.
