On the right passenger side on my truck I get a rattling sound. It isn't the seal around the windshield, but the cover/cowling over the antenna that's loose. Can't figure out how it sits in there, or if it can be tightened. Anyone know?
2012 Silverado 1500 btw.

On the NBS trucks, it is screwed. If you open the hood, you might see little ears with screws into the cowl. The ears may be broken.
