My friends are telling me my car is possessed. After replacing a dead battery a fan came on before I turned on the car. It does not look like a cooling fan. I cannot see the fan but when facing the engine it is near the front down and to the left. I think the cooling fans are in the middle, so I have no idea what is causing this fan to turn on. It drained my new battery overnight. The fan will come on every ten minutes or so and stay on for a couple minutes. If I could pull the right fuse at least it would stop draining my battery. Could it be a short? Any ideas?
