Hi Mark,
Come back and tell us how things go at the dealership; I know they'll take great care of you. I'll be glad to do what I can to help once you've received a diagnosis.

Hi Mark,...I tried the open and close thing with the engine running and stopped today, it didn't seem to do anything. I also looked up in the channels of the roof and could see any screws at all. Looks like I'll have to take it in...
Sure thing, Mark. I'll keep an eye on this thread to see when you have any news.Thanks Crystal, now I just have to find time to get the truck in. The whistle seems to be getting worse too.
Mark...
