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.

Okay, I checked that and it is not blown. Is the diode something I can check?

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.
