Same thing happened to our LeSabre. MY wife never uses the button, and when I replaced a headlight I wanted to check to see if the light worked. Pressed the button and it stayed on. Would not pop out. Took 10 minutes or so working with a thin screwdriver, and it finally popped out. Since it is not used, and knowing GM would want to probably want to sell me an entire dash, and perhaps a windshield, just to get a switch, I never bothered to price or get one. You might get on at the auto wreckers or if you go to the dealer, I am sure they will have the correct part number.
