I'm fairly new to the site and new to the 350z just picked up an 03 enthusiast last weekend. I attempted a search on this but my phone will not let me type in a search option so... my passenger side power window when I put it up on auto close or manual when it gets to its fully closed position it automatically goes half way back down. The only way I can close it is to jiggle the switch up and down real fast and even then I can close it but I can't seat it..if it hits the seated fully closed position it goes back down. Anyone else have this issue? If so how do you fix it?

 

you need to re-calibrate it
