Check for a switch at lower part of rad. Should see a wire harness & plug on a sensor at bottom of rad. This sensor/switch also operates fan on/off according to coolant temperature. You may need to disconnect battery to get at it safely.

Have you double checked the electronic switch type thermistat mounted on the radiator that senses the temperature of the anti freeze. You can jumper around the switch while the car is started and the fan should start running (watch your fingers).

CHECK TO SEE IF THE FAN RELAY IS FUNCTIONING BY SWAPPING IT WITH ANOTHER LIKE THE WIPER RELAY IF THEY ARE THE SAME. IF THE WIPERS WORK WITH THE A/C RELAY IN IT'S PLACE, THEN TRY REPLACING THE FAN FUSE. IF NONE OF THESE METHODS MAKE THE FAN TURN ON THEN REPLACE THE COOLANT TEMP SENSOR LOCATED NEAR THE UPPER RADIATOR HOSE INLET TOWARDS THE FRONT OF THE ENGINE. HOPE THIS HELPS YOU FIND THE SOURCE OF THE PROBLEM. LET ME KNOW. GOOD LUCK AND THANKS FOR USING FIX-YA.

The relay for the cooling fan is located on the left side (north america drivers side) of the rad about half way down or near the top (may vary) there may be two relays or one, replace them both. As for the fuse location it should be under your dash (fuse panel) looks like a big silver fuse similar to a zippo lighter, it will be marked in fine print "engine fan".

It depends, how long is it staying on after you shut the car off and how hot is the temp guage when you turn it off? The fan circuit is separate from the ignition and is designed to run until the engine reads a specific temp irregardless of whether the ignition is on or not. Hope this helps.
