window wont budge
Well my rear driver side window has quit rolling down. I thought It may have something to do with the fact that I converted all the switches to blue. Well ive tried 3 different master control switches and 3 different rear driver side switches.. no luck. The first day it did it... it sounded like it was trying to roll down.. but from there on it doesnt even make a sound.. as if no powers getting to it.
Question I have is how do I diagnose whats going on from here?

The fsm has listed where 12v gets applied directly to the motor, if you apply it and it doesn't work that'd tell you the motor was fried.
I'm not sure which pins they are but if you download the fsm it'll tell you

You don't need to pull the door panel off to do a voltage check.
Pop out the window switch from the door panel (pry up on the back end). Locate the solid blue and solid green wires in the wire harness connector. These go to the motor. These are wire numbers 1 & 2.
Leave the wire harness plugged into the window switch.
CAUTION: Those geniuses at Nissan put 2 solid green wires in this connector. They are not the same thing.
The wires you want are in the row of 5 wires. The wires you want are both the second wire from each end.
If you have a digital volt meter, it will be a little easier.
Put the positive lead on the green wire, pin 2.
Put the negative lead on the blue wire, pin 1.
Press the window switch to make the window go down. If the switches are good, you will read 12 volts.
If you are using a digital volt meter, press the window switch to make the window go up. If the switches are good, you will read negative 12 volts. If you are using an analog volt meter, you will need to reverse the meter lead connections. Analog meters cannot display negative voltages.
In summary:
window up - pin 1 (blue wire) is 12 volts and pin 2 is ground
window down - pin 2 (green wire) is 12 volts and pin 1 is ground

Did you do the voltage test? If so, what did you get?
While you say you don't hear the motor, how certain are you that is is not running? Have you put your hand on it to see if you can feel vibrations?
Since you have replaced motors and switches, it sounds logical that you might have a wiring problem. But if that is true, I don't think the voltage test that I described would have displayed correct results.

Without a volt meter, you will have to carefully inspect the wire harness for some kind of damage. The most vulnerable spot would be where the harness comes out of the door and goes into the pillar that the door bolts on to, the B pillar.

Thats the first place I checked and it appears there arent any issues. I did go out and buy another volt meter last night. When I have time to tear the door panels apart I will. Thanks again for all of your help!
