Hi all, first post here, I'm just hopeing someone has an idea. 1983 K% Blazer, just got it for 1500, runs great, all the lights work, even the power rear window works! The problem i have is anytime i move the defog/heat lever from off to anything, it kills the engine. If I'm quick enough in putting it back to off, it will start runnin again......Very strange. I've looked at the fuse box, but there are MANY wires going to it. I've already removed 3 or 4 wires that didnt go anywhere, just capped off at the other end. Anyone have any ideas, other that rewiring it?
