Good point. A friend suggested jumpering the relay, but I don't think it makes the noise all the time. This may be one those issues we will know when it finally fails.

I was hoping someone could suggest something on experience. For example, if I said my low beams sometimes don't work, our first thought is the relay. Which BTW, the GXP one went bad while my wife was driving it. I was on a mission trip, so I told her I would fix it when I got back. Then she gets a recall notice for the low beam relay. She took the car into the dealer, got it fixed before I got back.
