Well as far as Z's go mine has been pretty much the norm.... Second tranny Aftermarket HU after 2 or 3 bose i lost count tire problems before i did the suspension so naturally my windows were bound to mess up. Its the passenger side and it gets stuck in the down position occasionally, but if i hit the door a couple times it normally will go back up fine... is that a regulator problem or a motor problem?

 

any body?

 

regular...... but in mine i just roll it down all the way (when its already down all the way) and try to roll it back up... that usually works

 

i had a driver side motor and handler replaced under warranty for getting stuck. Window will get stuck from going up or down for a breif period of time then you'll hit the button again and it will go up/down like it never messed up. $300 fix, so if you have warranty i woudl use it. (they are well aware about the window problems, and shouldnt give you a hard time)
