Alright ive got a problem with my clutch fan it doesnt kick on. ive replaced the clutch still nothing it doesnt throw any code not even with the key trick. truck will heat up from 180 to 210 quick if im idleing and ac wont work when idleing(signs that fan isnt engageing)but works when driving. i couldnt find any cut wires or anthing, check voltage on pins two of the pins read 4.8v another reads 12v. nothing on the other two. Any input would help id even run a manual switch if possible
