Possible Temperature Sensor ( there are usually 2 or more in a car nowadays), fan relay, blown fuse, or ... bad radiator fan motor. Of course there's the possibility of a bad connection at the fan itself or a broken wire, but the most common reasons are listed above. Also, check your coolant to make sure you're not running extremely low. If the sensor isn't submerged in coolant, it will not read/function properly. Good Luck.

What would cause the cooling fan to only work when the air conditioning is on?
The Cooling Fans ( 1 Small & the a bit Larger ). The Big One Is For Cooling The Radiator For Normal Engine Usage. When The A/C Is On The Smaller Fan Will Run To Allow More Air To Be Pulled Over The Condensor And Radiator, To Better Cool The Water & Make The A/C More Efficent. There Is A Sensor In The Engine That Controls The Cooling Fan This May Have Gone Bad. I Would Begin My Testing Here First. Then Test The Fan To See If It Is OK. Hope This Helps

What would cause the cooling fan to constantly run on a Mazda 626 1999 model?
Answer: If you mean your radiator cooling fan, it most likely is a grounded or shorted circuit from the "cooling fan sensor" (internal) or a pinched wire. Depends on when it happened: was there any work done prior to this happening? IF not, then the sensor is most likely the issue. In this case, once you find it (normally the sensor is screwed into the bottom of the radiator), unplug one of the wires (or remove the connector) and see if the cooling fan continues to run, if the fan turns off, then replace the sensor.
