Car AC Repair

A car owner reported that their Toyota Camry purchased in 2018 recently encountered a problem with the air conditioning not cooling, but they couldn't pinpoint the specific cause. Now let's take a look at the specifics of the situation and how to solve this issue.   Firstly, this Camry has traveled 70,000 kilometers. The vehicle had its air conditioning compressor, condenser, and some AC pipes replaced due to an accident in the past. While it worked fine initially, the same issue recurred shortly after. Technicians used an AC pressure gauge to detect a high-pressure reading of 1.6 MPa and a low-pressure reading of 0.1 MPa. During high-speed operation, the high-pressure reading rose to 1.8 MPa, the low-pressure nearly reached 0 MPa, the cooling fan ran at high speed, but the air outlet distribution was abnormal. This led them to suspect a blockage in the system or ice blockage as the potential cause. Despite cleaning the filters, vacuuming, and refilling the refrigerant, the issue persisted, with the pressure readings remaining unchanged.     Next, they examined the condenser for Toyota Camry. Since the condenser is located at the front of the car, it's relatively easy to observe. They found abnormalities in the condenser: the upper left part was overheated, significant temperature difference in the upper right part, and the lower part was cooler, indicating that the refrigerant may not have been cooling through the condenser.   Further disassembly and inspection revealed that the condenser's inlet and outlet were directly connected, indicating an issue with the condenser. Consequently, the condenser was replaced, and after retesting, the air conditioning system returned to normal operation, finally resolving the issue.
