How to Unlock the Rear Air Conditioning in a Passat?

[LaAniyah]

Passat air conditioning panel's REAR button is the lock key for the rear air conditioning control panel. Here is the relevant introduction: 1. Classification of car air conditioning: Generally, from the perspective of car configuration, it is mainly divided into manual air conditioning and automatic air conditioning. Adjusting the air volume has nothing to do with the compressor. As long as the air conditioning is turned on for cooling, the compressor will always work at full speed. The temperature adjustment of manual air conditioning is just about how much hot air is mixed into the cold air. In actual use, the temperature inside the car cannot reach the condition for the compressor to stop running. 2. Differences in car air conditioning: Generally, manual air conditioning is equipped with a non-variable compressor. Automatic air conditioning can also use a non-variable compressor, which works on the same principle as manual air conditioning, but with an automatic thermostat device added, which can adjust based on the difference between the in-car temperature and the set temperature.
