Why is the Camry's heater blowing cold air on the left and hot air on the right?
2 Answers
Camry's heater blowing cold air on the left and hot air on the right is due to a malfunction in the servo motor of the air conditioning duct, which prevents the warm air from being distributed evenly to all ducts. When this occurs, it is recommended to inspect the servo motor in the air conditioning system's duct. The air conditioning is an important comfort feature in a car, used almost daily during winter and summer. The Camry is a mid-size sedan under Toyota, equipped with two types of engines: a 2.0-liter naturally aspirated engine and a 2.5-liter naturally aspirated engine. In terms of body dimensions, the Camry measures 4885mm in length, 1840mm in width, 1455mm in height, with a wheelbase of 2825mm.
Buddy, I've been driving a Camry for years and have also encountered the weird issue of one side blowing cold while the other is hot. It's most likely a problem with the temperature blend door in the AC system. This part is located behind the dashboard and controls the distribution of temperature between the left and right sides. If its actuator gets stuck or the motor fails, the air on the right side tends to be warmer while the left side stays cooler. The Camry's dual-zone AC is pretty advanced, but it's prone to this kind of issue as it ages. It could also be due to a blockage in the air ducts or incorrect settings. I suggest you avoid keeping the car in recirculation mode too often—more ventilation helps reduce blockages. If you encounter this issue while driving, try restarting the AC system first to see if it resets. If there's no improvement, it's best to take it to a professional shop to check the wiring and sensors. Replacing the part costs a few hundred bucks, but don't delay—over time, it can affect the overall heating performance, making winters tough. This issue isn't uncommon in Japanese cars, and if you're handy, you can even remove the panel to inspect it yourself.
