The aforementioned dimmer plugs into the cluster if I recall correctly, so check to make sure it's plugged in properly. Also double check all the wires to ensure one of the harnesses didn't partially or completely pull off. Check the solder joints on the terminals where the switch plugs into the cluster PCB.

The switch itself is a fairly robust design, so I'll bet it's a loose plug or wire. At any rate, you can find them at junkyards, and I even have a spare good used one if you need it.
