Without proper cooling, driving can be a hot and bothersome affair. While the coolant keeps your engine temperatures low, the air-con keeps you and your passengers from overheating too. If you find your car AC not working one sweltering summer’s day, your AC may be experiencing one of the following problems. You can have it promptly repaired at your nearest Lincoln dealership.
Only Warm Air Is Blowing
When the air blowing out of an AC vent refuses to cool down, you may have a refrigerant leak. Refrigerant is the substance that flows around the AC system, changing from gas to liquid form and back again, generating cold air in the process. If the refrigerant ever leaks, the cooling process can’t happen and the air will blow warm.
Alternatively, a variety of other faults can cause the cooling system to fail, including a clogged metering device, a malfunctioning temperature blend door actuator, or some other kind of restriction inside the system. A skilled technician will probably be needed to diagnose and repair the problem.
Leaking Greasy Substance
If you notice a greasy, transparent substance coating any of the AC’s hoses or lines, your refrigerant may be leaking. It’s often difficult to spot a refrigerant leak, but a technician can inject a special dye into the system to highlight the source of the leak.
Restricted or Halted Airflow
If the air-con’s air is blowing weakly or not blowing at all, you may have a fault with the blower motor, blower motor switch, or blower motor resistor. This is often a relatively easy issue to diagnose and repair.
Strange Noises from Your AC
Some AC issues create strange sounds inside and even outside your car. Clicking, squealing, rattling, or grinding might indicate debris trapped in the vents or fans. Odd noises may also result from a damaged AC belt, a loosened belt tensioner, a compressor problem, or something else.
Bad Smells Coming Into the Cabin
Mold, fungi, and other bacterial growth can sometimes build up because of the moisture that tends to accumulate inside a car’s AC system. This problem is especially likely when the AC is disused for months on end over winter. If you have bacterial growth in your AC, you’re likely to smell an unpleasant moldy smell whenever you switch your AC on.
Malfunctioning Compressor Clutch
The slight click you hear when you turn on the AC is the compressor clutch engaging. If this compressor clutch fails to engage one day, the refrigerant may be too low, perhaps because of a leak. Otherwise, the clutch itself may be worn out or broken, preventing it from accessing the engine’s power to run your AC.
