This assembly is housed inside the rear door, just below the glass(rear window). Access is gained by removing the door panel & moldings from the inside with the door open. Like side doors don't expect easy access, but rather a hole that you must reach into to work.
The entire shelve that holds the wiper arm and wiper motor assembly unbolts from the firewall in one piece. Once this shelve is out of the way the alternator will be exposed.
Remove the door panel and check for power and ground at the motor connector. If you have both power and ground the motor has failed.
