Should the stereo and air conditioner be turned off before the car is turned off?

First of all, we should form the good habit of turning off all the equipment.

Secondly, let me talk about air conditioning. If you don't turn off the air conditioner before turning it off, it will not only be bad for the circuit, but also cause water accumulation in the air conditioning system. Turn on the air conditioner again, there will be an unpleasant sour taste, which is the smell brought by those accumulated water for a long time. So your best way to turn off the fire is to change the air conditioner to wind 1 2 minutes in advance, which will not affect the temperature inside the car, but also effectively control the accumulated water.

Finally, the audio problem, in fact, I will give you an example to understand. If you listen to music with the stereo on at home and then have something to go out, should you turn off the power on the terminal board directly or unplug the stereo, or turn off the stereo first and then turn off the power? Of course, you choose the latter. Yes, the facilities in the car are the same. Don't treat them differently just because they are in the car. The circuit principle and maintenance measures are actually the same. The same is true for air conditioners. When you turn off the air conditioner at home, you must turn off the air conditioner first and then cut off the power supply.

Protect your car, and your car will protect you and your family.

Good luck.
