check for 12 volts at connector. position 1 will feed the black/red wire, position 2 black/yellow, position 3 black/ green. if nothing at any of them , then fuse box is your likely cause. if you have then motor. resistor pack should still allow 12 v to motor so i doubt that is your issue.

where are the other two bolts   UNDER THE SOUNDPROOFING??

sorry but don't understand term ..... if you have then motor   etc etc .....ALSO  Is the resistor pack a separate item and how do you test that

Sorry, I should have written that better. If you have feeds to the connector , then it's likely the motor is faulty.
The resistor pack is separate. To test it you can check resistance with multimeter set to ohms.

The bolts , I will see if I can find a picture for you. Has been probably 12-14 years since I've looked/done the job.
