01 Taco Power Window issues

Windows can't roll down or up. Changed the switch on both the driver and passenger door. checked the child lock button. The only time that it worked was when I connected the window motor directly to the battery. would be interested in any links you may have in getting to the bottom of this.

Thank you

 

Fuse or Relay?

Anything else that doesn’t work?
You or anyone worked on truck before P/W’s stopped working?

 

Have you checked your Power fuse (30A) in the interior fuse box?
If that's good have you checked for power at your window switches on the Blue/Red wire and ground at the master switch on the White/Black wire?

 

I had an issue on my truck when I first bought it. All windows would work expect the rear drivers side. I replaced everything I could think of, and nothing. I started chasing the wires with a multimeter and I found, strangely enough, that the plug under the driver's side kick panel I believe was just loose enough to cause the one window not to work. I unplugged it and clicked it all the way in and it worked without issue.

 

First off thank you all for your response. I've checked all the fuses. I tested all the relays because I'm not sure where the power window relay is located. Took the driver's side door apart and tested the window motor directly to the battery. Replaced both driver and passenger side switches. I looked at the wire harness on the driver's side. This all started when I left for a month for my daughter's wedding last year. I came home, and the windows stopped working. I live on an island; the heat and humidity are hardcore year-round. Any ideas and possible solutions are extremely and profoundly appreciated.
