Hi, I am working on my neighbors 2005 F150 king ranch, while he is away with the military, and need some help. All the trucks issues point to fuse 14, however it is not blown, nor has it ever.

No AC
No cruise control
No reverse lights
No day time running lights
ABS light is on
Brake light is on

I've read a lot of posts about all these issues being caused by fuse 14 popping, however, like I stated before, fuse 14 is fine. . .

Anyone ever experience this one?

Thanks,

Chris

 

and i forgot to mention that I have unplugged the pcv heater to no avail.

Also his "mechanic" friend installed his battery in backwards, and I wonder if that could have fried something or melted wires together or something along those lines
