Hi, I'm looking for help figuring out what this is before I bring the truck in somewhere.


I have a 2011 5.0, and yesterday and today, first days I've even used the heat this season, I hear a series of short and quick knock or clicks during start up. I don't know if that's related. It just seemed too coincidental. I almost thought there was a baffle or something jammed up in the ducts. Lasts about 5 seconds. Its pretty loud. It sounds like its right behind the dash, or traveling through the vents.


Any ideas?


Nothing crazy for mods. Just the basics.

I have the same issue, it has something to do with the A/C, as it doesn't do it in mine if I have it off when I start the truck.
