Saturn Repair Problems? Ask a Mechanic for Answers ASAP
Unplug the front passenger switch, turn the key on. All wires should be ground except the brown wire. From the drivers door press RF window up, the unplugged RF switch, either the light blue or tan wire should be power now and the other remain ground. Then press down and see if those 2 wires swap polarity. The same test can be done at all passenger doors, just different wire colors. This tests the master switch and wiring. The test from the switch to the motor must be done while plugged back up, but the same power and ground and polarity change occurs out of the door switches to the window motors. Let ms know those results, and use the wire diagram below.
You want a excellent 5 star answer & I would like to be rated the same for providing it. Consider I don't know your skill level & I can't see, smell, hear, or touch the vehicle. It may take a few back and forth replies. Try your best to respond with good detail so I can do the same. I normally log in at 3pm and work late. A rating is required. Your rating me, what I type.
