Problem has been driving me nuts - intermittently passenger window, rear windows and doorlocks will not work. more often then not they won't work. won't work from the driver door control or any of the other doors. That is the windows are stuck until the next "window of opportunity" presents itself and they start working. Nothing seems wrong with the window lockout button/switch.

To top things off, the (haunted) rear driver side window every ~30 mins or so, rolls itself down an inch. never up...just down.

I've looked at the driver window control circuit board and of course to the naked eye it looks fine. And all cables are seated fine on it.

It's the intermittent thing that is so strange - there seems no ryhme or reason for it. I expect (99%) that it's a faulty circuit board but just wondered if anyone had any other ideas. looks to be about $10 of electronics on it - now doubt that is irrelevant with what infiniti wants for it!

thanks.
