Your A/C IS BLOWING HOT AIR
Hot air coming from your A/C likely means there’s a major problem. When water gets into your A/C, it combines with refrigerant and creates a highly corrosive acid that literally eats away at the parts of your A/C system. This acid can ruin rubber seals that prevent the refrigerant from leaking. If the refrigerant leaks, it can cut back on your A/C’s cooling power.
There'S A WEIRD SMELL
A funky smell coming from your A/C may mean it's time for some attention. If your A/C is blasting a weird smell in your face, it could mean mold—and, therefore, water—is present. The culprit might be a damp or dirty cabin air filter, or it could be a blocked drain in your evaporator case.
IT HAS WEAK AIRFLOW
Excess moisture in the evaporator core could cause the building of mold and other debris that block airflow into the interior of your car. A loss of air pressure may also signal that there’s a restriction in the evaporator core or the blower motor is failing.
