How to Repair a Cooling Fan Relay in a 1994 Mazda Protege
The cooling fan relay in your 1994 Mazda Protege is responsible for keeping the power running to your cooling fan's motor. A faulty cooling fan relay can cause poor air conditioning performance and also overheat your engine. If you want to tell if the cooling fan on your Protege is working properly, start the engine and let it run for a a few minutes, then turn on your air conditioner. If the fan fails to engage, it's likely the relay will need to be replaced.
