My friend, someone spilled coffee or a soft drink on your console, and gummed up your switches. They should have a nice firm movement with a detent and a click.

Chances are, all you need to do is pull them out and give them a good spray with WD40. I've had to do this several times in the past 20 years, but all are still working great. Also, while in there you can transplant the drivers switch to the rear, since that is the one that sees the most use.

1. Find the black plastic 3" by 5" (approx) ring that surrounds the shifter.
Slide a credit card or padded wedge gently under it and lift it straight up. it won't break, it's held in by slip pins.
2. Pull the ashtray, and find the two phillips screws on the rail under the inside of the ashtray holder. Remove those, then pull the ashtray holder out - it sometimes sticks a bit, but wiggle it. Observe the light wiring.
3. lift out the coin tray.
4. Push the wooden console/switch holder forward and lift it right up.
5. Pull the wires off everything, then you can see how to just pop the switches out. You might not pry on the wiring sockets with a metal tool unless you unhook the battery!
6. Spray liberally with WD40, work them a bit, and reinstall. all the window switches are interchangeable.

If they still don't work properly, check Ebay.

Very easy, took longer to write this than to do it.

Oh, the 15 second fix is to spray the WD 40 from the top intio the rocker arm of the switch, but that's sooo crude.
