Thank you.There's no way to turn off that light. You could put tape over it, or if you want to not have tape showing on your OHC trim panel, you can easily take it off - then block off the light and reinstall the panel.
In this thread I posted pics of how to remove the OHC.
Overhead console removal
Anyone know how to take down the overhead console? I want to access the wiring but can’t seem to figure out if it’s just clips or there are hidden screws. Thankswww.tahoeyukonforum.com
