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?

While installing the new used motor and regulator from the junk yard, I found that the old one work just fine by using a battery and connecting it directly to the regulator. I used the same method of testing the switch but this time I check the voltage at the connector from the regulator. I found that when hitting down I would get a good 12v but the up will hit only about 9-10v. I'm Guessing it's something to do with the wiring at this point. Maybe the switch is bad too, but I'm not sure at this point. I just wiggle the wires and at some point it started hitting 12v again. It's working again now so i guess I just reused the orginal motor as do further testing. It sucks that I took everything apart even the motor and regulator just to put it back in, live and learn I guess.
