I have a 1997 Ford Ranger and there is what I believe is a relay switch just under the glove box. It keeps beeping and making a noise like it is trying to engage.
Can someone tell me what this relay switch is for? What does it control on the vehicle?

 

Welcome to FTE.
I see you don't have any replies, so I'll see if I can get things started. Are you having problems with anything thats in time with with the noise????
