How do I fix that annyoying rattle in my AC vents?Thanks Slow35th for this entire procedure
Here is a fix for your rattling A/C vents. The vents rattle because of a weak spring that pushes the vent shutters together.
1. Items Required:
Remove the vent that is rattling and open your favorite beverage (very important)
Disassemble the vent by gently releasing the tabs around the vent.
Remove the plastic bow/spring assembly from the center of the vent.
Remove the factory spring from the plastic bow.
Cut a heavy bobby pin slightly shorter than the factory spring and put slight bends on each end of the cut bobby pin as shown.
Reassemble the bow and bobby pin as shown and put the vent back together. Your vents will be noticeably tighter and best of all will no longer rattle.
