Back window problems

[B-27]

I bought a 94 4runner a few years ago and everything worked fine. Now I'm having issues with my back window . It will roll down with the key but I have to roll it back up by the switch and the switch won't work when trying to roll the window back down again. Any thoughts on what the issue could be?

Still having issues with the rear window. Been having no luck on finding anything helpful on the internet.
