Default Caravan power window not working

Hi, I have 1999 Dodge Caravan SE 3.3L
From a few months ago, the right side power window is not working
intermittently. few hours or a day.
When it does not work, both left (at driver's door) and right door's window
switch are not working.
Other equipments include radio, lights, horn, air conditioner, back seat's
power windows, left power window
are all right.

I checked fuses under driver's seat and the hood, every fuses looks fine
when I pulled and see.

Is there any points to check them out? TSB?
Do I need to uncover the right door panel to see inside of cable?
Any advises I appreciate. Thanks for reading.

Obviously something between the fuse and *both* switches. They're
obviously both fed from the same fuse, so they both get power from the
same source at the same time. However, I can't imagine what would be
between the fuse and the switches except /possibly/ a relay, but that
relay should be /ahead/ of the fuse in the circuit. On intermittent
circuits, checking fuses does no good. When a fuse blows, it will not
intermittently unblow itself. It might be loose, however, but that's
unlikely with how tightly these fit. Maybe bad wiring upstream.

The way to check is with a voltmeter or trouble light. Ground one
end/probe, and use the other end/probe to check for power on the fuse in
question *when the windows are not working* so you can see if even the
fuse is getting power. If the fuse gets no power, go upstream in the
circuit to the next available connection you see. Check for power there.
Keep following all the way to the battery if you have to.

Probably a bad relay, if no power to fuse at time of failure.

If you *DO* have power to the fuse, it's got to be between there and the
switches. Look for loose wires, connectors, etc., and also look for
corrosion. All metals "rust". It's called "oxidation", actually, and in
copper wire, it's green. Look for that at all connections. If you find
it, there's a reason for it. Maybe moist conditions, but in copper, I'm
not sure. Regardless, work the connections and make sure they are CLEAN
and TIGHT.

If that doesn't solve your problem, then I'm stumped.

Thank you so much, HIH, CJ.
I'll do check them with my voltmeter,
hopefully I get a point of no power and fix it.
Thanks!
