Thanks for the reply and pics. Got the switch out with no problem. Will order a new one.
Thanks,
Fred

I just looked at the switch and there is a small set screw that holds the knob on. Loosen the screw, pull the knob off then unscrew the bezel. Before you change out the switch try tightening the set screw. Sometimes they get loose and the knob may turn but the shaft doesn't. If the screw is loose you may have to turn it slightly while tightening to make sure it seats on the shaft properly. And, yes the switch does "click" when turned.

Check the ground first. I had the same thing happen. It had lost its ground.

How is the switch grounded? Is it grounded against the dash board when it's mounted?
Thanks,
Fred
