1 Answers
Audi A5 air conditioning relay is located in the fuse box in the engine compartment. Working principle of car air conditioning relay: Turning on the air conditioning switch sends a signal to the air conditioning control unit, while simultaneously sending a request signal to the engine. If conditions permit, the engine sends an approval signal to the air conditioning control unit, which then activates the compressor relay, causing the compressor electromagnetic clutch to engage. Function of the relay: To regulate the start and stop of the air conditioning. When the interior temperature reaches the current set temperature, the sensor will instruct the relay to stop the cooling response of the air conditioning; when the interior temperature rises above the current set temperature, the sensor will instruct the relay to initiate the cooling response of the air conditioning.
