1997 Plymouth Grand Voyager, 195000 miles
The rear vent windows have stopped responding to the switch. The left window was the first one to stop working -- it had been opened and then would not close. We finally were able to close it manually. A few months later, the right window stopped working as well. A few months after that, the right window began working again, but only for about a week -- after that, it stopped again.
I'm wondering if the switch is the problem, and if so, how difficult is it to replace?

Yes it could be the switch or the wiring or the motor(s); it may also be the crank arms that connect the motors to the windows.
You’re going to have too test a few things to find out who is or better said who isn’t doing their job.
Pop the switch (easier said then done at times) out of the driver’s door panel; may have to remove the door panel.
Leave the switch connected electrically; turn the ignition switch to the run position and get out your test light.
For the vents you’re going to be dealing with the red/white, dark blue wires for the left side and the dark green, gray wires for the right side.
With the test light connected across the red/white and dark blue, press the switch button for the left vent. The test light should light in both open and closed positions. Do the same for the right vent using the Dark green and gray wires.
If the test light lights for both buttons and both positions; then the switch is likely NOT the problem.
To test the motors; remove whatever trim that is in your way to get to the motors. You should find the same four coloured wires at the perspective corners.
Connect the test light across the disconnected motor connector (wiring harness side). If the test light lights, when the switch is operated for whichever side you’re testing; then it’s likely a bad motor(s).
There’s a chance that this is not an electrical issue; but rather the “crank arm(s)” that might be seized and the motors are not strong enough to move the windows. Before you begin any of the above tests; have a helper operate the vent switches. Go back to where the motors are and listen if you can hear anything form a hum or a click coming from the motors. If so then it “could be” the crank arms that are seized.
