2006 Yukon XL - the backlighting for the transfer case buttons and rear wiper controls are not working. Buttons function okay, but no backlighting at night. I changed out the transfer case button module with a different one and found same issue, so it's not the light bulbs. Any ideas on what do to next? Very annoying to drive at night and not see the backlit buttons.
