When horn is pressed, you can hear a clicking sound from the passengers side (under dashboard) from what I found searching, it sounds like I need to replace the central junction box? I read that the relay is integrated into it.

Hello,

Yes, the horn relay is part of the alarm and horn module that is located behind the glove box on the passenger side. It controls the anti-theft functions as well.

It is a solid-state module and cannot be tested.

I have attached the wiring diagram as well as the replacement instructions below.

Please let me know of any questions.
Thank you.
