Is Your Car AC Not Working? Visit Your Toyota Dealer Today

​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​We all love warm weather, but we also need a trusty car AC when the day gets just too hot. When your car AC is not working, it can make a pleasant drive feel almost unbearable. Fortunately, your Toyota dealer is here to help. If you have an AC problem, our expert technicians can repair it for you. These are some potential AC issues.

Water on the Floor

A wet passenger carpet on a warm, sunny day is a sign that something is wrong. The cause of this strange problem is water generated by the cooling process overflowing in the cabin. The evaporator coil holds chilled refrigerant from the compressor. As the AC fan blows over the air over the coil, it chills the air and removes humidity. The humidity is converted into water, which collects in the evaporator heater box.

The evaporator heater box has a drain pipe that drains the water out of your car and onto the ground. In time, the drain pipe can become blocked by mold or bacteria. If water can’t escape your car, the evaporator heater box will slowly fill up and overflow. The heater box is positioned in front of the passenger cabin section, and overflowing water will leak onto the carpet. We can clean or replace the drain pipe to fix this problem.

Refrigerant Leak

Refrigerant is the gas that enables the AC to work effectively and chill the air. It changes between gaseous and liquid states during the chilling process. Over time, AC components can become worn or damaged, and this can cause a leak in the AC system. Refrigerant is pressurized in both its gaseous and liquid states, and this means a tiny hole anywhere in the system can cause a rapid loss of refrigerant.

Unlike most other potential car leaks, a refrigerant leak is impossible to see with the naked eye. Refrigerant is odorless, colorless, and evaporates when in contact with the air. We can trace a leak in your AC system by feeding a UV dye into the compressor. We then use a UV monitor to trace the refrigerant’s passage through the AC. Once we spot the leak, we can permanently seal the hole to fix the problem.

Noisy AC

A smoothly functioning AC makes almost no sound. If you listen very carefully, you can hear the quiet click of the compressor clutch switching on and off, and you’ll hear the sound of the blower motor. If these sounds are replaced by rustling, rattling, or grinding noises, it’s time to visit us for an AC checkup.

Rustling or rattling noises could be made by dirt, leaves, or other debris rattling around the AC ducts. Grinding noises, in contrast, could be caused by a damaged AC bearing. We’ll check the ducts and your AC system and fix the problem.
