Focus brake light fault

disconnect turn signal switch wires @ column, put power to wires to brake lights. that cks wiring to lights. next put power to wires through turn signal to ck switch. Power runs from brake light switch to turnsignal switch, to lights.

Check the brake light fuse first and then the brake light switch. Fuse in the fuse box and the switch works off the brake pedal under dash.

The Focus was desinged in Europe,Think German.......Vw has a similar issue.The brake light switch goes bad.......no lights no shifting out of park.

yes it sounds like the turn signal switch is defective, the brake lights go through that switch as well.

I have a 2000 ford focus no brake lights. with the brake lights the transmission would not go into drive .replaced the brake light switch checked fuse replaced turn signal switch with no results then i moved onto the wiper switch and replaced it as much to my supp rise it fixed the problems

The power goes through the turnsignal switch befor it gets to the tailights.

Replace the brake switch located on the brake pedal shaft.

start with easy thing first are you sure both bulbs are ok ? get a test lamp
or make one!
get a good 12v bulb attach wires to side of bulb one to the terminal on base of
bulb,tape together now you can fined volts
hand brake on out of gear?

turn key on go inside car above the brake

theres a switch pull the plug off
put one end your test lamp to earth (the car body) and the other wire put to the terminals on the plug you pulled off if you get your test bulb to light its the switch thats faulty

replace switch if you have power at the switch and still no lights make a short bit of wire take back the insulation a bit so bair wire is showing make it in to a u shaped and put in to plug above the
brake that you pulled off you should now have volts(power) in the boot useing your new test lamp
to fned it make good all earthing points its somewhere between the switch and the boot?
if you fine when brake is pressed you get more than one light on its a bad earth
if you have no power at the switch ts prob fuse box fault tthry wll known for bad solder joins
good luck ps dont foget to replace plug

only one light not working indicates a bad circuit at the plug on the back of the light housing or in the wiring between the light and the dash swith
