Those are the kind of stories I like!

In this case, when the windows fail, they BOTH stop working. They won't go up or down. They don't even try -- no noise at all.

So it's something common to both, but that doesn't narrow it down much.

Good idea.

The reason I haven't gone right for the switches is that *both* windows fail together, every time.

I need to take another look at the schematics. I'm an electro-mechanical tech but I worked for Metro in D.C., so I'm used to railroad symbols. I find the Nissan (and most other auto mfrs') prints somewhat hard to follow in places.

That said, my assumption is that the voltage is being dropped somewhere 'upstream' from the motor control switches.

I'm guessing that there is single 12V source that splits and feeds both doors.

Check your fuse. maybe the contact is dirty. Then check the plugs to the components. Amplifier might be in the passenger kick panel. Thats where they are on the Hardbody and Pathfinder.

Good suggestions, thanks.

Part of the problem is that the fuse panel cover does not indicate which fuse feeds the window motors. I'll need to look at the schematics to figure out the path.

The other thing is, the problem is intermittent -- right now they're working.
