Recently I got a problem in my Nissan Versa power window motor (Driver side), about 3 weeks ago, sometimes the window goes goes up and down normally and sometimes it stuck and doesn't move at all, after some days, the glass doesn't move at all.
I wonder how can I diagnose the problem? do I have to replace the motor or the main switch? I have noticed that motor got an encoder whearas the other motors don't and they just got two wires of power (+ and -), why it's the only motor that has an encoder, event though it does the same function as others (goes Up and Down)?
