How to Turn Off the Air Conditioning in a Buick Excelle?
3 Answers
To turn off the air conditioning in a Buick Excelle: If the air conditioning is in heating mode, simply turn off the blower by rotating the air volume control knob to the 0 position. If the cooling function is activated, after turning off the blower, you also need to press the AC button to turn off the compressor. The Buick Excelle has dimensions of 4587mm in length, 1798mm in width, and 1463mm in height, with a wheelbase of 2640mm. This model is equipped with two sets of drive systems. The Excelle 18T variant is powered by a 1.3T Ecotec dual-injection turbocharged engine, paired with a 6-speed DSS intelligent transmission, delivering a maximum power of 120kW and a maximum torque of 230Nm.
I've been driving the Buick Excelle for almost three years, and turning off the AC is super simple. Just look for the button labeled OFF on the AC control panel on the center console—press it once and the entire AC system shuts down completely. If your model doesn't have this button, don't worry: turning the fan speed knob to its lowest setting works just as well, as airflow will automatically stop. Some owners might not realize that pressing OFF while in auto AC mode is the only way to fully deactivate the system; otherwise, even if fan speed drops, the system continues running in the background. In winter, it's best to turn off the AC button before shutting down the fan to prevent moisture buildup in the ducts that could lead to mold—this also helps avoid unpleasant odors. Making a habit of switching to natural airflow a few minutes before parking helps protect the compressor too.
The control logic of the Buick Excelle's air conditioning system is actually quite intuitive. The key is to locate the red or gray OFF power button, which is positioned slightly to the right of the center on the AC control panel. Pressing this button directly will shut down the entire system. For those who find this cumbersome, there's an alternative method: manually turning the fan speed knob all the way to the left, which also effectively turns off the system. However, I should note that operations differ in automatic AC mode - pressing OFF is necessary for complete shutdown, as simply adjusting the fan speed won't suffice. Additionally, before turning off the AC, it's advisable to switch to external air circulation mode. This allows the ventilation system to clear out the humid air post-cooling, a detail that significantly helps reduce odor issues. During summer when parking for extended periods, remember to turn the mode knob back to the regular air supply setting before shutting off the AC, as this helps prolong the system's lifespan.
