I've got a 2007 automatic Saturn ion with 85,000 miles on it and when I adjust my power side mirrors, I can go up, down, and right. But weirdly they won't move left when I press the left direction button. Wondering if I need to replace just the directional switch or some kind of wiring to the side mirrors.
You should check the power mirror switch first. All the switch does is change poles to power the motor one way then reverse on the same axis plane. Suspect the switch but first suspect the wire going from the door to the body..could be one wire broke. Those wires are bending everytime you open close door.
@Dion Excellent answer. As precise as it is concise. Well done.
@Dion you are a lifesaver! changed the power mirror switch 2 weeks ago and it's been running like a champ.
@webber223 you should give Dion a checkmark on his answer if it solved your problem.
