How to Turn Off the Highlander Air Conditioning?
2 Answers
The method to turn off the Highlander air conditioning is as follows: Press the A/C button to turn off the Toyota Highlander air conditioning system. When the indicator light on the button goes off, the compressor will shut down. The Highlander's air conditioning works the same way as other car air conditioning systems, relying on the compressor for cooling. Therefore, turning off the compressor means turning off the car's air conditioning. Below is an extended introduction to car air conditioning: 1. Car air conditioning is divided into manual and automatic air conditioning. Their main principle relies on the engine rotation. When the A/C switch is turned on, the electromagnetic clutch engages, transferring the engine's power to the compressor. The compressor circulates the compressed refrigerant to the evaporator, where the refrigerant vaporizes, absorbing heat to produce cool air. The fan then blows this cool air into the cabin. 2. It is recommended to turn off the A/C switch two to three minutes before reaching the destination while keeping the fan switch on to allow the blower to continue blowing air. This helps dry the evaporator coil, preventing bacterial growth. Since the evaporator coil is cold, surrounding water vapor condenses into small droplets, which is why water drips when the air conditioning is on. If water remains after parking, it can lead to mold growth over time, affecting health.
I've been driving my Highlander for almost three years now and have become quite familiar with turning off the AC. See that circular knob in the center console's climate control area? There's an OFF button at the lower left - just press it to completely shut down the entire AC system. If you can't find the OFF button, here's an alternative method: First turn the temperature knob all the way to the highest setting, then press the AC button to turn off the compressor, and finally hold down the fan speed decrease button until it reaches the lowest setting to stop the fan. In summer, don't turn off the AC immediately after shutting down the engine - turn it off a few minutes early to let the fan dry out the cooling pipes, which helps prevent mold growth. Also, after turning off the AC, it's recommended to switch to external air circulation for a while to let in natural air, otherwise the cabin can get stuffy.
