Symptoms of a Bad AC Evaporator
The Auto Air Evaporator, sometimes referred to as the evaporator core, is one of the two heat exchangers in an A/C system. The evaporator is usually located inside the vehicle, often deeply hidden under the dash. Refrigerant (years ago referred to as Freon) enters the evaporator in the form of a low pressure liquid and is metered through a device called an expansion valve or orifice tube.
The evaporator is the part of the system that gets “cold” air passes through it and into the cabin through the vents in your dash.
