Brake Lights not working

Fuse 52 in the engine compartment fuse box (15 AMP) , white /green wire at the brake light switch should have power with the ignition key on or the problem is between the fuse and brake light switch. With the brake light switch pressed the power is transferred across the switch to the green/ white wire. This wire stays the same color back at the rear lamps so pedal pressed the wire back at the lamp should have power. Try bridging the two wires at the brake light switch see if the lights now work, if they do the switch is faulty or adjusted wrong.
