• Ignition off
• Check the air conditioning (A/C) relay connector. Check for contact resistance and oxidation
• Reinstall the components, reconnect the connectors etc.
• Ignition on
• Activate the air conditioning (A/C) relay.

  A " clicking sound" should be heard when the air conditioning (A/C) relay is activated.

  If the air conditioning (A/C) relay is now OK, the cause of the fault was loose connections in the connector.
