Review on GM Genuine Parts 25877453 Dome Lamp & Reading Lamp Switch by Mark Bullock

works! Much better than paying for a new lamp at the dealer. You just have to get a little creative. First remove the map light with the torx in front near the windshield and just gently pull the other side down as it is simply held by two slots. This switch has 3 wires. I cut 3 blades from an unsoldered thermal (crimp connector) and put 1 in each of the 3 slots, then soldered a wire to each of them (the black wire stays in the middle, the other 2 don't care. Voila!
