Can any one help? Work on a 1986 300 SDL, had an electrical problem stemming from courtesy light wires being slammed in the door. Have the entire floor of the vehicle cleaned out to cut out the shorted wires and replace. But now to my next problem, the passenger seat has the problem of trying to go to the full rear position. All of the other functions work correctly with the seat switch. I can't seem to find a simple wiring diagram to show how to trouble shoot. Any Info would be appreciated.

Is it possible the seat adjustment contacts are dirty?

 

Possible too.try manually see if the motor work fine.switch can be try by using multi tester
