Didn't get a notification someone posted. Yeah, I have that knocking noise, and my lazy (removed), instead of fixing that, I just shoved something in the switch that recirculates the air. That stopped that. I need to fix that issue too in the future, but right now, it almost sounds like my blinkers are on, but really slow, so my guess is that it is a relay in the dash on the driver side. If it wasn't so darn hot, I would go play with it right now.
To make it stop I can either shut the radio off, or pound on the top of the dash with a closed fist. That will make it stop until I hit another bump in the road
