I have an 05 f250 5.4. When I parked this morning I got out of my truck and I realized I left my lights on. I went back into shut them off and the truck wasn't beeping like it normally does when you take the keys out and they are still on. Then I also tried and it doesn't beep when you leave the keys in when the truck is off and you open the door. Anyone know about this or what fuse it would be?
