The TCCM's for the Blazer have been updated and have a different part number. It should list the part numbers the updated model replaces at least the one I got off ebay did. I am at work and don't have the part number for the new one handy but I am sure someone here will have it. Or do what I did and keep looking, you will find it. I got a killer deal on mine. I think it was around $240 US including shipping to the border which seemed pretty good to me as the dealer here in town wanted $850 bucks for the one he had.
Try part number 12577412 and see if they list your old TCCM.
