is fuse # ***** and # ***** good and show 12 volts with the key ON ?
with a test light or a multi meter
if you slam on and off the hazard switch a few times will the rear work even for a second or two ?
also we need to know if the orange wire at the brake switch connector shows 12 volts at it and if so when you step on the brake will it show 12 volts at the white wire at the stop lamp connector wire ?
test light is cheaper and should work fine
you can visually inspect those 2 fuses to see if they are blown first before you go buy a test light
ok we need to do those tests next i said
if it is getting power yes
but from the sounds of this if those 2 fuses are good the orange wire at the brake switch will show NO volts
then we know which way to go with this
it would make sense for what is not working that the orange wire from one of those fuses is split off and not powering the brake switch or the power to the hazard switch which usually if you follow the orange wire from the brake switch it should come to a splice with other orange wires and usually that splice is bad
ok let me know
is the white showing 12 volts when you step on the brakes ?
you replaced the brake switch with a new switch ?
can you unplug the brake light switch and be sure the terminals in the connector are good and not burnt at all if the terminals look good if you jump the orange wire termianl to the white terminal in the connector will the brake lights work ?
with a paper clip or a wire jumping the 2 terminals together
if jumping the 2 terminals makes the brake lights all come on then either one of the terminals is loose or bad or the brake switch is defective or it is not correctly installed
do the front signals work ?
and fuse 16 showed 12 volts at it ?
but no hazards in the rear ?
ok we have to have 2 problems here
first we need to correct the NO 12 volts at the white wire terminals at the brake switch when the brake pedal is pushed
you are sure the white does not show 12 volts when you step on the brake pedal and the terminals are all good and not burnt or damaged in the brake switch itself ? and visually the white wire is not cut or broken in that area of the brake pedal ?
not likely if the orange shows 12 volts and the white does NOT show 12 volts when you step on the brake lights shows the switch is defective or not locked in correctly or a terminal issue in the connector
if the white did have 12 volts then we could have a wiring harness bad
i think once we get 12 volts back on that white wire when you step on the brakes and then replace the turn signal switch assembly that also has the hazard switch built into all your problems should be corrected
