    the temp sensor? it could be reading cooler than what the actual temps are and therefore not telling the fans to turn on. I am not sure if that has seperate relay to turn on fans other than the AC........I guess you have to turn on your ac pump if the motor temps are getting up there at least until you get this figured out. Not sure which fuses and relays they are off hand..........hopefully someone chimes in who knows which numbers they are for sure........

    Definately not the Coolant sensor, replaced it this morning, old one was reporting 30 degree variance, engine was hotter than it said it was.

    I've had this same problem for a year and a half. I've spent hours online and even on the phone discussing it with forums members.

    So far, no solution.

    as a last resort, you could always get aftermarket equipment and have them operate independantly.........
