Rattle eminating from under the rt.rear pass quadrant of the car for about 20k miles at highway speeds (65-80mph+) Tech took the car for a couple of days and isolated the problem as loose rivet/fasteners. Problem solved.Very quiet ride now! Stripped and sanded the rust from the door bottom. Primed and painted the rusted area. I expect I will have to re-visit periodically. AC blower output and air quality deminished. Decided to replace the cabin air filter. Very easy repair . The filter was entirely full of "junk". Noticed immediate improvement of volume and quality of air flow. Rock Auto $21 inc shipping
