My car was involved in an accident with impact to the driver side headlight. THe coolant system, AC condensor, fan motor and radiator were all replaced under the hood. The body shop brought the car back to the dealership and the water pump fuze blew and was repaired. SInce I have gotten my car back the fan runs excessively at external temps above mid 80s even when the AC is off and appear rather loud and fast running. Prior to the accident the fan shut off when the AC shut off; and upon test driving 2 other 2010 Prius' the fan only came on with the AC running and then returned to the quiet Prius motor. Also the radiator fan appears to be pumping some pretty hot air out of the front vents. What is potentially wrong with my vehicle to have these noises that did not exist pre-accident?
