What is the reason for the rear air conditioning not cooling in the Highlander?
2 Answers
The rear seat air conditioning in the Highlander cannot adjust the temperature. If temperature adjustment is needed, it must be done via the front central control panel, as the rear seat air conditioning can only control the airflow volume. Relevant information about car air conditioning is as follows: 1. Introduction: The car air conditioning device (air-conditioning-device), referred to as car air conditioning. 2. Function: It is used to adjust and control the temperature, humidity, air cleanliness, and airflow within the car cabin to the optimal state, providing passengers with a comfortable riding environment and reducing travel fatigue; it creates good working conditions for the driver and plays an important role in ensuring safe driving as a ventilation device.
I'm a car owner and have been driving a Highlander for five years. I've encountered the issue of the rear air conditioning not cooling once. Common causes include insufficient or leaking refrigerant, especially due to aging pipes; abnormal compressor operation, indicated by unusual noises; blocked air ducts, particularly when the rear filter is dirty and restricts airflow; electrical control issues, such as faulty temperature sensors where the setting is correct but the temperature doesn't drop. There's also the possibility of malfunctioning rear air vent switches or short circuits in the wiring, leading to unstable power supply. If you face this problem, first check if the filter is clogged—simple cleaning might solve it. For more serious cases, it's necessary to test the refrigerant pressure, otherwise, the rear seats can become uncomfortably hot in summer. It also affects driving safety by causing distraction. I recommend not delaying and visiting a professional repair shop early to prevent minor issues from becoming major ones.
