Why is the Accord's air conditioner blowing cold on one side and hot on the other?

The car itself can be equipped with a dual-zone air conditioning system, meaning there are separate temperature control knobs for the left and right air vents, allowing individual adjustment of the air temperature on each side to meet the different temperature preferences of passengers. Here are some tips for using the car air conditioner effectively: 1. Ventilate before turning it on: After the car has been exposed to the sun for a long time, open all four doors and the sunroof to allow air to circulate for 3 minutes. This quickly reduces the interior temperature, making the air conditioning more effective when turned on. 2. Use the recirculation mode wisely: Recirculation mode blocks hot air from outside, creating a sealed space inside the car where air circulates rapidly under the air conditioning to cool down quickly. Once the interior temperature has dropped, it is recommended to switch to fresh air mode every 30 minutes to refresh the air inside, then switch back to recirculation after 5 minutes. 3. Turn off the air conditioner in advance: Shut off the air conditioner 5 minutes before parking to protect the engine and save fuel.
I've encountered the issue of one side of the car AC blowing cold while the other blows hot during driving. This is usually caused by a malfunction in the dual-zone temperature control system, such as a stuck blend door or actuator, resulting in uneven distribution of hot and cold air. It could also be due to incorrect AC settings, like unsynchronized left/right temperature knobs. First, check if the settings on your AC panel are consistent. If the settings are correct but the problem persists, then hardware issues should be suspected - like a faulty actuator motor, poor wiring connection, or sometimes inaccurate sensor data. This type of failure is common in vehicles like the Accord. From my veteran driver experience: if you feel uncomfortable while driving, open windows for ventilation or turn off the AC, then visit a professional repair shop ASAP to read trouble codes with diagnostic equipment - don't attempt DIY disassembly. Regular AC system maintenance and filter cleaning can prevent such issues, otherwise it affects comfort and wastes time. Safety first, after all.
