How to fix "rear doors open" or "liftgate open" instrument cluster messages
Hi Guys, This will be my last post here, as I no longer have a Tahoe. I thought I'd share the solution that took me a year to track down.

Upper Headlight Housings Preparations The LED bulbs don’t fit quite as nicely in the upper housings. In the low beam position, the holes are too small for the LED bulbs to fit through.
