I cannot get radiator fan to turn on automatically. I have replaced the coolant temperature sensor as well as the radiator fan relay. With the relay power supply cord, I have confirmed that pin 1 A112 gives a 12 volt reading. I have also confirmed that pin 2 N23 gounds and starts fans when supplied a direct 12v current. I cannot get pin 4 k173 to give a reading, even when I left the car on to overheating temperatures (which I was hoping the sensor was just waiting to send a signal). Although maybe I should not have, I applied 12 volts to pin 3 z723 and it popped electricity. When I put my meter on it though it seemed to be fine with the 12v reading. I have checked fuse 13 in the Power Distribution Center and have confirmed continuity. Additionally, I get a 12v reading from the positive. However, I cannot get a reading going to the ground.
Please help, I am losing my mind and I know nothing about any of this until I started googling yesterday.
have the same problem?
