I have a Nissan Altima 2008 3.5 SE. The driver's door power-window doesn't work using the button on the door panel. However, if it works when a key is inserted in the door lock and rotated clockwise.
Also, when there is a rain or if I pour some water where the power-window slides in, the button on the door panel works.
I want to fix this myself. Before I open the door, I wanted to know where the issue would be. Is it a loose connection? Or does the motor required greasing?
