Hello,

The indicator light that is inside the switch is a non serviceable item according to GM. You will have to replace the unit.
That being said, it is possible to take apart that switch and access the bulb. It is small bulb that is soldered to the circuit board. Unfortunately GMC does not provide us with any part number for that bulb as they state it as non serviceable.

Please let me know of any questions.
Thank you.
