ok, I have a 94 chevy 4.3 vortec v-6. The cruise control will not work. I replaced the brake switch under the dash, checked the fuse (which according to owners manual is the gages fuse). replaced to whole box and wire that runs to the tpi. What else do you suggest. When I try to get it... I don't even get a light. NOTHING. is there a relay somewhere? or do you think its gonna be the blinker switch?
