Recently my 01 Dodge Ram 2500 started dhaving a problem where it will click when I try turn it over as if the battery’s were dead then after a few clicks it’ll start up. Sometimes I could drive it all day then turn it off in tims drive thru and then it won’t start til I try turn it over a couple times. It usually doesn’t do this if it’s plugged in. It was also fine for the first couple months of winter

I’m not sure where is the starter relay located
