sounds like you guys need to reset the limit switches. should be an easy fix if you know how to remove your door panel. there's a DIY on here about how to do that kind of thing.

 

There is a post about this,you need to reprogram the window motor.Some has posted how to repair this i did it and it solved the problem,just do a search in the forums and you will fine it.

 

i have CF doors,my ds door did this too..my g was originally BS i had it painted black and when painting they paint got in my main door harness..it was cleaned via infiniti dealership.problem solved...id say theyll prob clean ur harness.

 

I replaced the window motor last night on my 06 coupe and now it's doing this too. Hoping to find an answer.

 

When I use the auto up function on my driver window the window drops 3 inches after reaching the top. I removed my door card and attempted the reset procedure on this website

http://infinitihelp.com/diy/gcoupe/projects/infiniti_g_coupe_power_window_resetting_procedure. php

and it made the window worse after I released the reset switch and rolled the window up according to the procedure. My window only went up 3 inches and stopped. And will no go up any higher. I am lost. Can anyone help point me in the right direction. I would really like to prevent spending $100+ at the stealership.

Thanks a ton

 

You have to follow the instructions exactly. With the door open close window all the way up. DO NOT use the AUTO feature on the window switch. Just pull up slightly until the window goes up. SHUT THE DOOR. While pushing the reset button lower the window all the way down without stopping, DO NOT use the AUTO feature, Release the reset button and close the window without stopping all the way up and hold switch for a few seconds, again DO NOT use the AUTO feature. Window should open and close normally after this.
