Vert rear window issue Options

[jlspec]

I running into an issue where my passenger rear window would have issues going back up after going down. At first I thought it was my button but after getting another one installed I still get the same issue. I spoke to a local junk yard employee who said it's something to do with the motor. I find it odd because when I press up I don't hear the motor click or anything that will signal a power going to the motor. When I press down I hear it click. Anyone has any idea what this might be? If it is the motor where would I get a new one? Does toyota still sell it? Also anyone know where I can get a diagram of the vert rear windows?

I tested the switch last night and it's working just fine. I did some search on the web and came across a few saying that it was the regulator. I'm planning on going to the junk yard again today as there currently is one 97 vert there. Problem is that this yard I go too isn't cheap but its the only with a vert at the moment.
