Hi, I have a 94 Chevy Astro van, and i noticed this post was the closest i can find on the internet about my problem
http://www.automotivehelper.com/topic887708.htm,
It was about the speedometer abs light and not shifting, I tried it hoping it would work, i cut the purple wire, but it didnt work so i cut all the wires to the abs (since i couldnt get it unplugged) but once i did that the abs light went off, but the speedometer used to bounce a little bit and give weird readings, but now its pegged at the bottom, i repaired all the wires, but still have the same problem, replacing the vss was the first thing we tried. The Fuse is still blowing, and have take the pcm out of the circuit to see if that was the cause, but the 15 amp brake fuse near the bottom of the fuse box, what do i do now?
