How do you remove the headlight and parking light switch unit from the dash of a 2000 Buick Lesabre?

The dash faceplate in which the switches are centered pries outward from left edge (about 1 1/2" high, 8" long). Plug and wire are then exposed for disconnecting, and plate can be removed and taken to workbench. Then it's up to you to figure out removal of switches from plate. I watched my dealer remove the plate w/switches and take them to workshop to free them up when stuck ON!
