power window troubles

A couple years ago, the passenger side back window would no longer go up from it's control switch, but would work from the driver's controls. Just recently other windows began doing the same thing - either not going up or down. Sometimes the driver's controls would help and sometimes nothing would work to move the window. My question... what are possible elements that could be causing the problem? I checked the fuses and didn't find one that was labeled specifically for the power windows, however they all seem fine. Thanks for any suggestions!

Switch contacts tend to lose proper conductivity over time. Too little current flow, not enough juice to the window motor, window stops going up or down, or seems to labor more than it used to. Different contact for each direction, so yes, the window can and may still work in one direction and not the other. It helps sometimes to use the switches so they don't oxidize as much from dissuse over time, but eventually any switch will wear out. You can pull the door panels off and depending on the switch, clean the contacts, or replace the switch. I would pull the door panel, unplug the switch, attatch a meter, and check for continuity through the switch before assuming the switch is bad for sure, and if you can find a similar make/model, might be worth a trip to the local salvage yard if the dealer wants too much for a replacement. For that matter, you can start at the yard, pull a door panel and see how the switch works, before you disect your own car, if you are the unsure type.

If however, there are other issues with the windows such as clunks, scrapes, or other odd noises eminating from the internal window mechanisms, switches may not be the culprit. So, to start, I would try simple stuff, which for myself would be the switches.
