I put this together and figured I would share it with the forum in case it might help somebody.

I've had quite a few power mirror switches that have worked for only one side or sometimes even a certain direction will work intermittently. In fixing this fairly common problem, I've found that the problem is not always bad corrosion but sometimes loose posts (often E, F, G, and H). Its easy to test this without even taking the switch all the way apart by attempting to wiggle the posts on the back of the switch. I've had quite a few switches where all four posts were loose. A small bit of solder correctly applied while holding the post in position will fix the problem. The contacts should be cleaned though as corrosion can be a concern.

To Greter Fang - Great table thank you! Any chance you know how to wire the switch to the harness? I have one red, one lt Blue and 2 Yellow (4 total) on each side from the electric mirror. How do I wire it to the switch? Thank you

Did a search and found this thread, but the link is no longer working. Was hoping someone could re-post the info, as I need to do this testing on the Power Mirror Switch.

Thanks

What link? You mean the picture in the first post? Shows up for me...

Yep, can't see the picture. All I see is the little picture square. Tried opening the image in a new window with no luck. Pilot error? Or something to do with my Browser (Chrome)?

Try Again.....

Thanks. Worked for me now. Appreciate it

Do you now it the swith is used on any other car?

A similar switch is used on Camaro's ( 82-89, mounted in the instrument panel). The insides of the switch are the same, but the mounting ears are different. You can make it work by gluing it in, but it's not as good as finding a Fiero switch.

Easiest way to bench test these is to put a small battery, say 9v w/ battery connector from dead whatever, tied to main + (A) and - (B).
Then connect light bulb or meter to motor's output and push a button for output tested.
Get cheap jumper wire kit will help a lot.

Still in the car then just back probe the connector w/ test light or meter.

Leave meter alone for each output, just make sure volt read same ignoring - sign.

Sometimes reverse switch setup has a crap contact and no or low volt for one direction.
(Fiero PM direction is basically a smaller switch for PW switch and can have same problem.)
