Help with relay identification - 92 LX

Hi - please help, experiencing frustration. Under the drivers side dash, near the radio, are these 2 relays. They are sort of attached to the buzzer/chime mechanism. The brown one appears to be the horn relay. It’s the other one, marked E4LB13A025A2A that I am trying to identify. Mine is making a strange buzzing noise, sounds like it is malfunctioning. Unplugging it does not seems to affect anything in the car. Replaced with a new relay and the new one makes the same strange buzzing sound also.

Please help!

I believe it’s the dimmer for the radio display. Unplug it, and turn on your parking lights with the key in ON (so the radio is on). The display should dim (assuming if factory)

If aftermarket and you wired the dimmer wire in it should also dim


I would need my wiring diagrams to really double check
