Where is the car air conditioning evaporator located?
2 Answers
The car air conditioning evaporator is located inside the glove compartment on the passenger side, behind the cabin air filter. The function of the car air conditioning evaporator is to convert high-pressure liquid into gas, which is then blown out by the blower to achieve cooling. Common causes of car air conditioning evaporator failure include: 1. The expansion valve's adjustment range is too small, resulting in excessively low low-pressure; 2. Insufficient refrigerant in the system, leading to low evaporation pressure; 3. Clogged interior circulation filter; 4. Malfunctioning temperature sensor causing the compressor to run continuously. Solutions for car air conditioning evaporator issues: 1. Check if the temperature control sensor is properly positioned; 2. Replace the temperature control regulator; 3. Inspect whether there are any faults in the air conditioning computer control.
The car's air conditioning evaporator is usually hidden under the dashboard, to be more precise, near the footwell of the front passenger seat. That spot is quite concealed—you'd need to remove the glove box or some lower interior panels to see it. Why is it placed there? Because the air needs to be cooled by the evaporator before being blown out, and its position near the front of the car makes it easier to connect to external air ducts. If the AC isn't cooling properly, the evaporator might be the issue—perhaps leaking refrigerant or frozen pipes causing blockages. I often encounter this issue when repairing cars; cleaning it can be a hassle, but regular maintenance can prevent major problems. This design placement ensures faster and more efficient airflow, though it makes repairs more challenging. The exact location varies slightly by model—SUVs might have it positioned lower, while sedans are more compact. Either way, knowing this helps stay calm when troubleshooting issues.
