2016 Heater Noise
2016 F-150 XL has a noise in the heater system only on the "floor" setting, going down the road. Goes away with recirculate, off, or any position other than floor. Sounds like paper or cellophane rattling in the plenum. Just started. 18000 miles. Drives me nuts. Anyone else have this problem or ideas.
