FORD 2007 F-150 v.3 - Manual (Page 248)

If the parking brake is fully released, but the brake warning lamp
remains illuminated, the brakes may not be working properly.
See your authorized dealer.
Brake-shift interlock - floor-shift transmission
This vehicle is equipped with a brake-shift interlock feature that prevents
the gearshift lever from being moved from P (Park) when the ignition is
in the ON position unless the brake pedal is depressed.
If you cannot move the gearshift lever out of P (Park) with ignition in
the ON position and the brake pedal depressed, it is possible that a fuse
has blown or the vehicle’s brakelamps are not operating properly. Refer
to Fuses and relays in the Roadside Emergencies chapter.
If the fuse is not blown, perform the following procedure:
1. Apply the parking brake, turn the ignition to LOCK, then remove the
key.
2. Open the center console bin.
Using a screwdriver, carefully pry off
the console finish panel surrounding
the shifter mechanism by inserting a
screwdriver into the latch slot as
shown.
3. Remove console finish panel
assembly to expose the inside of the
gearshift.
