I noticed the other day when i drove my D there was a lot of clicking coming from the relay compartment. I then noticed that the cooling fans were coming off and on approximately every 10-25 seconds. The fans would then stay on for anywhere from a second to about 5 seconds and then turn off again. I was curious about this so I let the car idle and get hot. The fans did work properly when the car got up to 220 degrees and dropped it back down to about 190. I also noticed that the fans only act up when i have the heat on in the car. I installed the relay update recently. Any clue what could be causing this?? -Thanks in advance, Dave
