About door window

[juttdaman]

I have 2003 350z. The door window will retract down partially for cabin pressure relief while the door is open for closure and then auto go back up. The question is why will the window not go back up when the door is closed by itself. Is a limit(prox)m switch bad or need resetting.

What do you mean by the door closing itself? Last I checked, you have to physically close the door on the 350Z.

might have to clarify your question...so when your door is closed your windows dont seal? is that it? what do you mean when you say the door closed by itself? .......

when you open the door the window automatically retracts down. This is for when the door closes there is no cabin pressure to prematurely blow the seals out around the window when you close the door. Once the door is closed the window automatically extends back to the home position. The window is retracting down to far and not extending back up. I was wondering if someone had ran into this problem and knew of a faster way to fix than takeing the door completely apart to reset the switches. (Maybe just take part of the door apart or a certain location of the door) But I see no need to pay the techs to fix my door when I do the same kind of work on machines at a larger scale.

I've heard a some of the early cars window motors failing prematurely, this is the first problem like this I've heard of, and to clarify:when you open the window is dropping further than it used to and consequently will not go up on it's own once closed?

The window rolling down and back up whewn opening and closing the door is not for pressure. Interiors of all cars alreay have provisions for this. The function is there to provide positive sealing of the window. Many coupes don't have window frames. Doors that do allow the seal to be much tighter than typical on a non-framed window as the edges of the glass are sealed on both sides and around the edge. Frameless windows have the problem of having to release from the seal when the door opens. The function of the window cracking open allows Nissan to use a seal that seals around more of the edge of the glass. Get into a coupe with no window frame and no positive sealing and you'll notice more wind noise, particularly at higher speeds.

As for your particular problem, my speculation about this system is that There are adjustments built into the motor that controls this. Some early Z's and G coupes had issues with their windows rolling all the way down after it gets to the top if you used the auto-up feature. Dealers would try to use the adjustments but if that failed, they would replace the window motor. My thought would be that you have a different problem, but ultimately may require an adjustment or replacing the window motor. Though, I've never looked at the set-up in detail, you will likely need to take a closer look and do some troubleshooting...
