GMC Repair: Interior Switch Lights not working, auto salvage yards, lighting issues

Question
2001 Buick Lesabre. A number of control button lights were not working so I replaced the headlight dimmer unit and some of the lights are now working i.e. Exit and Memory 2, Driver Heated Seat. However the Memory 1, passenger Heated Seat, all steering wheel controls and dash climate control buttons still don't light up. Are there bulbs behind these switches and if so how do I remove the wood grain plastic around the climate controls to replace bulbs?

Answer
Hi
These switches your having lighting issues with DO NOT have bulbs. They use LED'S that are fed from the power coming to the switch(es). The only way to relight them will be to replace the switche(es) themselves.
You may consider used switches from Auto Salvage Yards for this.
Hope this helps.
Good Luck
