I have a 2003 Maxima SE (3.5L) with about 80K miles. Recently all my power windows, sunroof, rear defrost, and 2 seat location memory controls have stopped working. In addition to that, the bell that signals that the door is open and keys are in the ignition keeps ringing even after the engine has started (it used to ring 3 more times then stop); the dome light stays on for a full minute after the door is shut after ignition. I have checked the fuse for the power windows, and it is fine. I have also checked the most recently wiring diagram I could find, and it appears that the front driver, front passenger, and rear windows are all on separate switches, and it didn't appear that there was master switch that they all came to. I assume all these issues are related to the same electrical problem, due to the fact that they all started at the same time.
