Power window problem!

[Slick]

I recently got my windows tinted, and now the button for my passenger window on the drivers side wont work. the window rolls down using the passenger side button, so i know the motor isnt broken. My uncle said it is either a messed up wire or broken switch. He said i need to take off the panel to get to this switch to check it. Should i take off the whole door panel or is there a different panel right on the armrest on the door? Let me know ANY info thanks. And i know this isnt under the hood but i wasnt sure where else to post it!

Just bumping this back up. And I was driving yesterday and all of a sudden i tried rolling down the passenger side with my drivers side button and it worked but now it doesnt work again. Anyone know whats up??

Probably a bad contact in the switch. Can't help you with whether or not the entire panel has to come off tho. Have you searched for door panel or window? Should come across some threads, and I believe instructions for taking the door panel off.
