SOURCE: RADIATOR FAN
If you've got the hydraulic fan, check to see that the solenoid at the power steering pump is plugged in. My 1993 3.0 had this happpen, and that's what was wrong. You have to pull the front passenger side wheel off to access the pump. Just stick your hand up in there and feel around. You'll find it. One way to check is to let the car idle and turn the a/c on full blast. You should hear the fan start to roar after a few seconds. If it doesn't, then check the solenoid wire. Worked for me!

First, check the relay for the cooling fans. Not sure about Mazdas but Fords have two coolant temperature sensors. One for the gauge or light on the dash and one for the fan relay. Check and make sure the sensor hasn't went bad or come unplugged. If these don't fix it the fan itself may be bad.

The fans come on only when hot or the AC is on. There are many fuses that have to be good for it to work. The fan relay should have 2 pins hot with the key on, The other 2 should be ground. with the key off one should be hot and the other can then be ground the other pins that are ground one of them is the fan. the other becomes ground when the computer turns the fans on. If you don't have a pin thats hot at the relay all the time then theres a blown fuse or even the power wire from the battery at the battery

Check to see if the radiator fan relay has gone bad and needs to be replaced. Once you located the relay, (in the fuse box under the hood) Try swapping it out with another relay and see if the fans stop, if the fans stop working with the swapped relay, replace the relay. It's know for the relays when they go bad to stick and will have a close loop. Good luck and hope this helps. Keep me posted, be glad to help you get your car running 100% again soon.
