I'm Lee, a first-time newbie here. I'm also old and computer challenged to boot. Please bear with my fumbling. I just bought my first Jeep, a 2002 TJ. It didn't come with an owner's manual and I can't find an answer to my question. Occasionally an indicator light appears briefly in the upper right corner of the dash display. It's a three-sided box with an inverted V top. It resembles a house. What does it indicate?.
