The evaporator is used to exchange heat between the ambient air and the refrigerant in the air conditioning system.
How they work
The expansion valve and/or orifice tube injects the highly pressurized liquid refrigerant into the evaporator. The refrigerant then expands and evaporates.

Causes for failure of the evaporator can be:

Signs of Wear: Insufficient cooling of the vehicle cabin.
