im trying to pinpoint if the relay is bad or not....i tried to run a new ground as ive seen stated in other posts on here but it didnt help....i know the fan works on high because i ran a jumper from the battery to the fan and it works on high...then it took the plug off the back of the switch and jumped a wire from the brown to the other 3 terminals one at a time....2 would work,im assuming low and med.....but when i tried to jump to the orange wire(which runs from the back of the switch to the relay by itself) all it does is make the relay click.....does this mean the relay is bad?
