Nissan Repair: 1993 quest GXE power window issues, rear hatch, flex tube

Question
having problems with power windows.  last year it was ground in driver's door that was repaired.  all windows worked for a time (car was not driven much).  car just inspected and windows worked.  went to pick up. worked to open but not close.  they changed relay.  all windows worked multiple times.  we went to pick up again, worked once and then not again.  there are other electrical issues such as radio and cruise control not working and also during winter the dome light (for rear hatch) flickers. Possibly related or different issues?  rear air doesn't work and hasn't since 1996, but i have found answers to that.

Whatever you can do to help.  Thanks so much

Answer
I would think it is the master switch as a first choice.  You can check the wiring going to the door through the flex tube in the jamb.  Sometimes the wiring gets worn and that causes opens and shorts.  So, I would check the wiring and if it is not defective in the jamb area then I would be checking the master switch.
