Question about Chevrolet Cars & Trucks
With the car turned off and the battery disconnected, root around under the dash and find the wiring harness that comes down from the steering column. You may have to remove a dash panel or two to get at it. It should be connected to the car's main wiring harness with a plug of some sort. Disconnect the plug.
Using a multi-meter set to test continuity, test pairs of pins in the connector from the steering column, pressing the CC switch with each pair, until you find the pair that come from the CC switch.
Isolate the wires for these two pins behind the plug and scrape away a tiny bit of insulation with a knife blade, being careful not to cut through the wire. Test the wire pair again to be sure you've got the CC switch wires.
Cut the wires, leaving several inches of wire above the plug to work with. Using a good quality crimp connector (or soldering, if you know how and have the equipment), connect the two wires you just cut loose (the two coming from the plug, not the steering column).
Make sure there are no bare wires *anywhere* when you're done. Cover everything with heat shrink tubing or electrical tape, then use a tie-wrap to bind all the wires together again. Return the wiring harness to where you found it and re-install any dash panels you had to remove.
Reconnect the battery and go for a drive. The CC switch will be totally out of the circuit, but your CC should be permanently turned on.
Now here's the fun part. You'll have an extra momentary-contact switch on your steering wheel that's not doing anything. Just think of the possibilities... You could use it for an auxiliary air horn like on a semi-truck, or you could wire it into your brake lights so you could screw with tail-gaters without actually stepping on the brakes. Look for the switch somewhere on your brake pedal assembly and add two wires from the old CC switch to the contacts on the brake pedal switch.

JUST POP SWITCH OUT AND BULB GOES INTO SWITCH USE SMALL SCREW DRIVER TO REMOVE YOU WILL HAVE TO TWIST IT COUNTERCLOCKWISE TO REMOVE, TWIST CLOCKWISE TO INSTALL.

It sounds like your multifunction switch has an internal failure and needs to be replaced. This is the part that you flip to use the turn signals, wipers, cruise control, fog lamps, etc. This can be an expensive part, but it is almost certainly the cause of your concern.
Let me know if you'd like to know how to replace it. It is a fairly easy part to replace.
Hope this helps!
