Back window wont roll down

I have a 93 4runner and my back window wont roll dow. ive been reading some stuff and ive moved the back windshield wiper up and made sure it wasnt locked. every time i press the button or turn the key i can hear it trying to go down but it wont. every once and awhile itll go down if i keep pressing the button but not lately. I dont know if this will help but a couple weeks ago i got my car washed and it worked for a couple days then it just stopped.
Thanks for the help

 

Check your fuses, my 95 did the same thing and it was just a fuse.

 

Where are the fuses on the inside im used to my chevy and itd be nice to know where im generally looking so i dont waste my time
Thanks

 

It's been a while since I've had the 95, I believe they are on the bottom left hand side of the steering wheel.
