Have Ford Questions? Ask a Mechanic for Answers ASAP
You could try swapping the switch from pass rear to drivers rear. To rule out the switch. It is possible you have a bad main switch and drivers rear window switch. Also check for broken wires in the rear door bellows boots that are located in the door jams. These wires often break causing this type of problem.
Please let me know if you have any more questions. Thanks.
Does it have the auto up/down feature? is it working?
Look for broken wires in the drivers front door rubber boot.
swapping the switch will not work in this case.
reset the auto feature on the drivers window. roll window down and hold button down for 5 seconds, roll window up and hold for 5 seconds.
That could be the problem.
You have a bad master switch. The rears get their power through it.
Test the switch with a multimeter for continuity.
