After watching numerous YouTube videos regarding reflowing bad solder joints on GM's ECBM, I was disappointed to find my part doesn't appear to match any of the kelsey hayes 325 style modules, but rather is the 42 pin single connection (GM Part # 20817362). Are these prone to the same failure as their predecessor? Do I just need a new module and pay for reprogramming? (Mechanic quoted 3 hours to program, $400 for module). I guess I will check the junkyard first! Anyone know if this is specific to a TB model year, or can I use any TB i6 4wd module that matches? (minus SS of course). Thanks in advance. I have a new baby on the way and need this fixed before the snow flies here! 20817362.jpg aaa.jpeg

I was not, as I found one at a local junkyard for the same model year and tire size (important!) for $105. That and a front right wheel bearing and all my lights are now off!
