If the high level brake light is working, then the brake switch is working fine,

If it was a earth fault, then none of the other lights would work,

Can you check all the bulbs in the light cluster, had customer changing the wrong bulbs..

i dont feel this answer is helpful as the solutions you have given are only reiterating the information i have already provided you i thought you would provide an alterative to checks i have already made and informed you of.

Expert:  Mobilemick replied 2 years ago.
Check you are getting power to the Orange wire on the back of the light cluster,
Press the brake pedal down, and you should have 12volts on the orange wire.

i would appreciate it if you could get a wiring diagram, as ive tried all other options,.
Expert:  Mobilemick replied 2 years ago.
Have you checked to see if you are getting power to the orange wire on the rear of the light cluster, A wiring diagram would only show you this..
Block 94 is the drivers side tail light, the black wire (pin3) is earth, and the orange wire (pin4) is live from brakelight switch
Expert:  Mobilemick replied 2 years ago.
Reverse light switch is the blue wire(pin1)
Customer: replied 2 years ago.

yes there is power to the orange wire on both sides........

Expert:  Mobilemick replied 2 years ago.
Ok thats good, it shows the wiring is fine,
If you remove the circuit board and trace the silver part going to the brake bulb, check you are getting power there.
Customer: replied 2 years ago.
there is no power on the silver part of the board that goes to the brake lights
