Some 2006-08 Jeep Commanders may produce a rattling sound from the glove box area when the blower motor is turned on.
Likely causes for the noise, Chrysler said, are leaves, pine needles or other debris making their way into the blower motor housing.
A deformed air door baffle screen is the ultimate villain. Replacing the baffle screen with a revised unit, part No. 55037760AE, and cleaning out the housing should prevent further trouble.
