Default A/C Unit wont turn off.

I just came home to find my A/C-Heater unit on. the funny thing is that the keys wernt in the truck. I tried pulling the fuse but it doesnt turn it off. Has anyone had this problem? and if so how do i turn it off?

Thanks in advance!!

hmm, maybe you cut some wires shaving the tailgate handle

might be a bad relay or something causing it to ground out. there could be a tsb for it never know
