i have a 02 eco and for the past couple days the aux fan that kicks on after the car is off has not been comming on. i cannot figure out why. or find the relay which i think is causing the problem. when i turn the car off i can hear a click not sure if its the relay trying to kick on or some other completly unrelated noise, but it will click twice and then stop not nearly enough time for me to find it. any help / info would be great.
