Thanks for the post. I took the power coming into the front console switch straight over to the connector for the motor power and when I touched briefly to the termninals, I could hear the motor start to crank, so I'm sure the motor is fine (at least on this door.I haven't tried the other door yet). From the Haynes manual I have, it looks as though if either switch (front console or door) is crapped out the system won't work. The manual shows that the output from the center console switch is used as the input to the door switch (as thought they are in series rather than parallel).
