I have a 1994 mustang 5.l v8 convertible. I have changed my bulbs, breaklight switch ,turn signal switch , fuses, relays, and my brAkElights will not work but sometimes they work with the flasher button engaged what else could it be ? I have power going to the sockets in the truck tail lights work just fine. BrAkEs turn signals and flashers won't work ease help.
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)
