So here's the skinny....
My window made a "pop" sound when it reached the bottom of the rail after I pressed auto down on the switch. Turns out this was a small plastic gear on the regulator that broke...This was obvious. I replaced the regulator with a new OEM Nissan unit, lubed the rails, and cleaned the inside of the door like any car freak would!
This worked fine for a week then the window wouldn't go up again last night. It doesn't just fall down like before however I can push it down by hand. I can hear the amp click and the motor make noise when I press the switch but the motor does not go up without helping it from the bottom.
I inspected the solder joints on the amplifier (small box seen when you first remove the DRIVER'S SIDE door panel). I didn't see any obvious cracks like I've viewed from searches.
Should I be able to move the window up without pressing the switch? Stripped motor gear?
Is there a procedure to check the window amp (haven't found this)?
Any help is greatly appreciated...Jody
