I recently pulled the center vents out of the dash in order to get at the radio. When I tried to put them back in, the two rubber collars that go around the back of the vent and attach to the ducts didn't quite line up and got mashed. The result is that most of the air now shoots out into the inside of the dash. I tried taking the vents out and putting them back a few times, and tried contorting my hands in behind to slide the collars on better, but nothing seems to work. Am I missing something? Dan.
