For the past few weeks, I've had a rattle that has been driving me crazy... basically like a slight buzz or "metal spring" noise coming from the glove compartment after going over even slight bumps. It ended up being the TMPS sensor under the glove box.... the TMPS is basically held in place by two hand-tightened ***** which were very loose. Took 10 seconds to tighten them...noise gone!!

Hope this helps someone out there with a similar rattle!
