I had a mess of old switches but none of them worked in both directions. I guess after 30 years they wear out.

My last problem is the passenger side window switch. It only works in one direction. Sometimes it only moves the window up, other times it only moves the window down. It's not the switch. I have a new switch, and several used switches and they all behave the same way. Any one have any ideas? I figure I must have a bad wire somewhere, but I'm not sure how to test it.

I'm just suprised you still haven't fixed it after 4 months but lets give it a try..

Now the passenger window switch only works in one direction BUT...

sometimes it only moves up and other times it only moves down???

Up and Down.....TWO directions?

Hmmm....

I'm gona guess that if you replaced the window harness with a 2 door truck harness and you did not cut it up or molest it in any way, The wiring is not your problem. If not cut they rarely go bad.

Fugure which way they work and maybe we can help.
