Hey all,

I’ve had this rattle, it sounded like a Relay flicking back and forth constantly. The other day while it was doing it, I move the rear view mirror and BAM, the rattle stops!
After a little while it will rattle again, I just move the mirror around and it will stop for a while.

I had the wife ride in the car and listen for it, and yes, she confirmed the sound was from the mirror area. WHAT CAN BE RATTELING? I’ve never heard of this before.

Thanks for the help!
