I have a 96 blazer, the pulse circiut board went bad. The little prongs that most people resolder back together broke off, and dont have no area to resolder. So i am either going to buy a new one. The cheapest i found so far is a little over $16 at rock auto this is the link to it. http://www.rockauto.com/catalog/rafr...390074-3308632 but the board looks different from my old one, but i guess it dont matter since its an aftermarket part. Or to save a few buck i may find one out of a junk vehicle. My family just happens to have alot of late 80's to 90's vehicles that just sit around thats gm products. Is there a list somewhere of what would work off different models made by gm. I hope i put all the info on here. Thanks
