I have a 93 4Runner with power windows. When I use my passenger contols I can only roll the window down but not up. And from my seat I can only roll the rear passenger window down but not up. From the rear passenger seat I can roll it up and down. Also rear driver side goes up and down real slow. Anybody got suggestions as to how to fix this?

 

Your switches may be going bad or have corrosion/deposits on them. Try taking them apart and using some electrical contact cleaner on them. They may just not be making a good connection due to being worn.

As far as the back window goes, you should take the inner cover off of your tailgate and clean and lube the window tracks with some silicone spray. It really helped mine out a lot. Also clean and lube the track where the window slides up into the roof/back end.
