Hello everyone. I've been having problems with something shorting out and a fuse keeps blowing out. I have a 2001 zr2 chevy blazer. The fuse is ECM I. I also have the A/C fuse blowing out right as the engine cranks. Idk what that problem is? Would it also be tied in with the ecm fuse problem? We had looked at the computer, and it looked fine, no .. burns or anything looking wrong. It happens when I drive for a little while. It's seems to have been that: I drive for a while, and fuse goes out. I could drive again for a shorter distance, and then it goes out again. The distance seemed to have gotten shorter and shorter. Is it that I just need to look all over the truck at all the wires and see if anything looks bad? Or does anyone have any ideas where it could be? Ask any questions and ill be glad to answer. Hope someone can help me figure it out, thanks!

 

I had a problem blowing my ECM fuse from a melted wire loom on one of my manifolds so you can check there. Mind you, it was a 95 which has a completely different motor in it, but just an idea.

 

Ok, yeah. I'll look, thanks
