replaced control with a new GM one from ebay $100.00 shipped. Although my truck is still under warranty, I'm sure the dealer would have broken a few of the clips that hold the aluminum bezel around the center stack. They "love" warranty work. That trim was a ****** to take off with out breaking/bending! My old part was 84258726 the new part is the same with the last digit being a 9. As I'm sure, that in two years, this will happen again, I'm sending my old part to 1mr.repairman so he can replace all the led lights with quality parts and i will swap it back in when the new GM one goes on the blink. Kind of sucks for a $50+ truck!
