What is the cause of dim radio/temp dashboard lights with ticking in dashboard

 

How old is your battery?

 

A radio dimming and making a ticking noise often indicates electrical interference or a problem with the radio's power supply or components. The ticking sound could be caused by a variety of things, including a faulty power cord, loose connections, or even external interference from nearby electronic devices.

 

the battery is fairly new (about a year old); guessing I should check the connections behind the radio/temp control panel. thank you for responding.

 

What year 4Runner do you have, didn't see anything in your signature.

 

it's a 2004
