Sign of wear:

Lack of or insufficient cooling in cabin

Compressor: (Limited Lifetime Parts Warranty Protection) ♢

The compressor compresses refrigerant. The compression leads to a change in the refrigerant’s boiling point that helps create the cold air that is delivered through the HVAC system.

Excessive clicking sounds or unusual noises during A/C operation

Water Pump: (Limited Lifetime Parts Warranty Protection) ♢

The water pump is responsible for circulating engine coolant through the radiator and engine system to help maintain optimal engine operating temperatures.
