Hey guys so my car reads Engine Hot AC Off with the Fans running 24/7 when that code is up.(The car is not overheating) but the temperature gauge drops to cold like all the way down No engine Light. Eventually it comes on. I Changed the Engine Coolant Sensor and thought that was the fix but it wasnt. The "Engine Hot AC Off" comes on when i put the heat on full blast then the message stays on. When i reset the battery it obviously tricks the computer for a little and runs normal without the message. Does anyone know a fix ?
