If the cooling fans on your 2004 Mitsubishi Outlander are not working when the air conditioning is switched off, it may be due to a faulty cooling fan relay, a blown fuse, or an issue with the temperature sensor. The fans typically activate based on engine temperature, so if they aren't functioning, the engine may overheat. It's advisable to check the fuses and relays first, and if those are intact, consider having the temperature sensor and wiring inspected by a professional.
