Having a problem with the electric fan? Here's what to check: first make sure fan is free-wheeling. Spin it by hand. If no obstructions, use jumper leads off the battery to test fan motor. If nothing, motor is bad. If fan operates off the battery, find the radiator fan relay under the hood, and pull it out. One relay terminal will have a hot at all times power source, probably from a fuse link or a maxi-fuse in the fuse/relay box. Check that one terminal is hot at all times, using a voltmeter or test light. If you have air conditioning, turn the AC on, key on. Now, two terminals at relay should show power-the power feed source, and the signal from computer to turn the relay on.
Didn't say what kind of car or year you have, but here is how an older Nissan turns the fan on, without using the computer, and with no AC: the relay signal to shoot power to the fan comes from a thermal switch mounted in the radiator. When coolant reaches 194 degrees F., the thermal switch will close contacts internally, passing power to the relay's coil side of relay. Relay is energized and passes power to the fan motor.
For your car, you will have to check a wiring diagram to see how the cooling fan circuit is set up. The fan relay may be triggered by the computer or by a coolant sensor somewhere in the coolant system.
