I just watched a youtube video of changing the t-stat. Supposed to be 2 of them in there and there's a bunch of stuff in the way that needs to be moved to get at the thing. Nothing's ever easy anymore....

Edit to add: With the truck being 12 years old and these being the original parts, it makes sense for them to be worn out by now.
