I have a 06 town & Country touring. The liner next to the windshield was pulled down by the dealer to fix a loose ceiling mount. (had a rattle) The dealer has since gone out of business. They did not put back the liner correctly, and I can just fit my finger in the gap between the liner and the roof in the center of the roof next to the windshield. Is there a special tool to clip the liner back to the roof? I tried to push on it thinking it would snap back, but it doesn't seem to work like that. What do I do?
