The fans on my 2005 mustang gt will not come on at all. I bought a new fan assembly to replace the old one with and it worked for a while but now its not at all. I warrantied out the replacement and still nothing. I have checked the fuse relay and swapped them into the horn spot to see if the horn would work and it did. The plug for the fan looks good on the inside of it. Any advice would be helpful guys. Thanks in advance.

No wires look chewed on or fried at all.
