    There is a high speed and low speed control relay all the way over on the driver's side of the fuse/relay box. There are two resistors and two electric fans mounted on the radiator fan shroud, failure of any of these may cause over heating or failure of the fans to operate, If the cooling system thermostat fails to open this too could cause the over heating, It is important to get this checked out to avoid serious engine damage.

    make sure you have the a/c on because with this car if the a/c is not on all the time the fan does not work
