recently I had to replace my radiator fan due to the old one breaking but have been running into a problem. Its an aftermarket fan so I had to rewire it myself. I connected the black ground wires & the blue fan wire to the orange/blue car wire like the directions said. the problem is that the fan will not turn itself on @ a high temp. but will turn on/stay on when it's directly connected.
