I got in my truck today and the A/C would not work so I tryed to roll down the windows and they wont eather,and the fuse block were the window fuse and a/c fuse go have no power,is there a relay that controls those two things

 

Does any of the other fuses on the block have power, you couls also check the relays that control those functions

 

check all of your fuseable links mine did the same thing and that is what it was

 

If taht doesn't work ... Get an exorstist

 

Mine did the same thing, my key is actually worn out and wasn't touching the last pins in the ignition switch all the way. I got my dad to cut me a new key at our lockshop and it works just perfect now. Trust me I went through every wire and fuse on my truck and talked to my girlfriends uncle and his did the same thing, try and let me know if it works.
