Extended data:
The maintenance method of Citroen Elysee relay is as follows:
Turn on the ignition switch, listen to the control relay with your ears or stethoscope, or feel whether the relay vibrates with your hands. If so, it means that the relay basically works normally, and the electrical appliance does not work for other reasons. Otherwise, the relay is not working properly.
For example, if the air conditioner compressor doesn't work, you can start the engine and turn on the blower switch and the air conditioner switch. Then unplug the connector of the air conditioner compressor relay for judgment. If you can hear the sound of relay action, the engine speed will obviously decrease when the relay is pulled out and increase when the relay is inserted.
