I own a 2000 s10 blazer, 4.3 l, automatic tranny, automatic climate control. I recently changed out my blower motor, going through the hood, taking out the pcm and the coolant resovoir. I also cut the rubber to get to it. Well anyways, the old one was shot, so i bought a new one and installed it. Which it worked fine, but it would switch from hot to cold. It would stay on hot longer though, not sure if that matters. But then it just stopped working, same day. I checked and the seal on the blower motor was open, like to where you can see the back of it. Not sure if that could be the reason but yeah. Any ideas?
