Brake lights Have no brake lights. Found bad fuse. Still no brake lights but blinkers and 4 way flashers and tail lights work fine. Shifter lock button extremely hard to push. When cruse is on I have to push hard on the brakes to disengage cruse.

FUSES BAD OR MODULES AND SWITCHES
NO BCM brain box here.
USA car , canada is NO THE SAME electrics !!!!
so flashers means turns, and turns are dead all 4 corners or what? all flasters is HAZARD lamps switch
parks work.(tails and front parks)
turns fail all 4 corners(not told) and hazards dead too all four corners and brake lamps all 3 rear dead.
do not break the brake lamps.
grounds to all lamps good,(the failed ones)
0vdc on ground.
fuses are always first, a 20cent fix. is way and childs play test (or a look)
fuse 1 and 9 not blown in IP BOX x2 , 15amps
OMG fuse 9 runs brake lamps. is this clue , YES
the next in LINE is Electronic flaster not bad.
5 wires and the black ground wire not busted.G204
next in line is the very complex MULTIswitch (column)
next is the BRAKE PEDAL switch NOT BAD.
if not bad 12vdc (push brake pedal) leaves the switch
R/GL wire to all brake lamps including 3 center high mounted lamp and its G300 ground

fix brake lamps only first.
fix that and others get fixed for free (shirt tails free)
to test lamps at rear for brakes the pedal must be depressed . a 2 man job.
fuse 9, hot both sides. and is hot all the time bat side.
brake switch LG/R wire hot all the time key off too.
light green red !
step on brake R/LG goes hot, now. if not switch is bad
Red/light green. (means)

Suspect the multi-function switch. (turnsignal) these fail a lot.

the fuse is labled 'brake'

I would replace the fuse... and then have someone stand to the rear of the vehicle and watch the lights come on as I applied the brake... if the fuse blows again... note which tail light did NOT come on durring this test and replace the bulb.. it is grounding to itself and causing the short.

your brake light switch is the problem, check the fuse first.

The Blinkers and the Brake Lights are the same bulb. So check the brake light switch. Flashers use a different flasher unit, than the turn signals

I have a 2001 Ford F150, my brake lights dont work. Ive replaced the bulbs, checked the fuses,and the brake switch on side of the brake pedal was replaced. I still dont have any brake lights. My third brake light works fine, along with my running lights,flashers, blinkers.

you have a bad brake light switch

there are two turn signal flashers under dash one on fuse box and one next to the light switch have to look up behind dash behind light switch for second I had same problem

TURN SIGNALS WILL FEED BACK THROUGH THE TURN SIGNAL SWITCH.THEY ARE INDEPENDENT OUT SIDE ON THE CAR BUT NOT IN THE SIGNAL SWITCH.REPLACE THE SIGNAL SWITCH

could be both unrelated issues at the same time

worn indicator stalk
faulty relays

adjust or test the brake pedal stop light switch
