I know rattles are a unique situation and trying to find, via a computer, is next to impossible. That said, I have a rattle that "appears" to be coming from high on the right side of the dash. Like, behind the glove box. The noise is louder inside the car than out, even though the headers are close. The wipers work fine. The heater box appears to be tight. What else is in the area that might come loose? it is not a light tap, it's pretty solid and very tinny. I'm thinking remove the defroster grate and look in from outside the windshield. Any other ideas?
