GM has now issued a Service Bulletin for the IP snaps and pops as has been discussed in this Forum. The service bulletin number is #06-08-49-011. The service fix is to remove the defroster panel, remove the attaching clips on its underside, install anti-itch tape to the clip post and re-install the clips. Anti-itch tape is also installed across the slots on the IP top pad where the clips engage. We have performed this fix on a number of GM company cars and all have been successfully corrected. Thanks to the customers in this forum. You were one of the sources for discovery of this problem.
