Hi im a noob and I got a question. I have a 91 formula with the 350 tpi with the dual fan set up. My cooling fans wont turn on when they should. I have replaced the fan switch and the sensor but that didn't help. When I disconnect the fan switch the primary fan runs all the time. Now I know that's normal for it to run all the time when no signal is seen from the switch. I currently have it disconnected so I don't over heat. I am completely clueless as to what is wrong. I have checked all the wires and they are all good. Any help would be greatly appreciated.
