Thanks a bunch, Steve. I guess I'll play it safe and cough up the money to get the relay replaced. It's kind of funny that you mention the dome light in this, because I actually had my mechanic fix it. The PO had wired the radar detector through the dome light (as a means to get into the roof), which had left the light non-functioning. I was only able to repair it to the extent that it would turn on when the door opened, but my mechanic said that some wires were crossed and it looks all straightened out now. Anyway, thanks again!
