Check your high speed fan relay first. Also your resistor that plugs into fan may have burnt up. That's what happened to me . I ended up replacing fan assembly with a '13 assembly.

Runs from the middle of the fan to the top, passenger side of the housing. Mine just took a crap at 54k on my 07.

The relay itself is the metal box at the top, passenger side.

Check your owners manual for the relay location. It's in the engine compartment. I think it was a few $'s at an autoparts store.
The total fan assembly was less than $200 shipped from Tousley Ford. You can get the resistor, that is part of the assembly, separately for less than $50.
