My passenger window was not working. So today i replaced it but the motor does not work still. I checked all the fuses and nothing seems to be the problem, can someone help me out? I don't know what it could possibly be

 

#1, is the on-off switch on drivers door on? If so do you have a meter or test light.

Both motors wires rest at and must be at ground with motor unplugged. With light or meter test from known POS+ wire like at door lamp to each wire. The ground comes from door switch and goes through passengers switch. If not at motor plug check to see if it's at the two wires coming from drivers at passengers switch.

With digital meter connect both probes to the plug going to motor and you should see 12+ one way and 12- the other.

Hope this helps.
