Electrical problem
2004 Toyota Highlander 6 cyl Two Wheel Drive Automatic 31000 miles

I've read similar problems and solutions to mine, but not exactly, so here goes...

All of my 2004 V6 3.3L Highlander windows (except the drivers window) open perfectly well, but closing them takes for EVER (maybe 1/4 inch at a time or less every time I pull up on the switch). This happens from both the master switch on the driver door and each door's switches themselves. There is power going to each window (you can hear a click when the window switch is operated), so is it a problem with the master switch or relays? What do I need to do / buy to fix my problem?

The car has only 31,000 miles. I have owned it from new, and have not abused it.

Thanks
