Hey guys! I bought a set of new steering wheel radio controls for my '04 Yukon XL SLT w/ Bose, but am having an issue. Same thing would occasionally happen in my '03, but I always assumed it was the harness that had a bad spot as the problem was only intermittent. On this one, it is constant the second I install the new buttons. Double checked part numbers to make sure they were the same. With the old factory buttons, all functions work as they should, only reason for replacing is they are worn and lights are gone out on most. The 2 new lower switches work like a charm, give me all the info on the DIC, no problems there. The top 2 new ones are another issue. Left lights up correctly, but nothing responds at all, none of the buttons pressed result in anything responding. Right one is even better. Seek Up activates OnStar, Seek Down seeks up, Volume Up seeks down, and Volume down tunes down one frequency at a time. Put the old ones back in, all functions on both work exactly as should. I would simply say bad switches, but what are the odds that both are bad AND that my '03 did the same thing, just intermittently. Does something need to be flashed or reprogrammed for new switches? Seems ridiculous, but I wouldn't be surprised. Anyone else experience this when installing new switches, or am I just lucky?
