What is an AC evaporator and how do I know if it's bad?

The AC evaporator is the component inside your dashboard that absorbs heat from the cabin air to make it cold, and a bad one causes weak cooling, musty odors, or a refrigerant leak that drains the system. Because the evaporator sits in a damp, dark spot, it is a prime breeding ground for the mold that creates Miami's notorious musty AC smell. Over time, corrosion can cause it to leak refrigerant, which kills cooling and is hard to spot since the part is hidden deep behind the dash. Symptoms include reduced cooling, a sweet or moldy smell, and a system that loses its charge with no visible external leak. At Motoro Cars, our ASE-certified technicians confirm an evaporator problem with proper leak detection before recommending the labor-intensive repair.
