Rear wiper motor not running. Replaced with other identical but still not working. Is there a fuse or relay to check? What should be read over the connector pins?

Okay, I found a wiring diagram. Looks like fuse fifteen in the main fuse box powers the motor. There is also a rear wiper diode in the circuit.

It is in the line from the fuse inside the passenger fuse box. It is possible to open the box to replace the diode (at least a friend I called has done a couple) but it is not real easy to do. from what he said the box is a real pain to remove. The picture shows one of the diodes, there are two in there. Sorry I cannot be more helpful.
