At the Light;
You need to check Voltage + on the GREEN / YELLOW wire with Brake Pedal pushed down
Check Ground - on the WHITE / BLACK wire
Let me know what you find

hello?

Customer: replied 2 months ago.
Way over my capabilities I have no clue how to check voltage,
Expert:  Don 'Mo Lurch' replied 2 months ago.

You would need Test Light or DC Volt Meter & know how to use.....
Problem with this circuit, is the Brake Lights & the Center Brake Light go thru, what is called, a "Light Failure Sensor"
It could not be a Fuse, as the Brake Lights & Center Brake Lights use the same Fuse
Voltage & Ground needs to be checked to prove out Light Failure Sensor or wiring
IF you are not able to Test, then a Local Automotive Shop or Dealer will be your next step

did you need any more information?

Customer: replied 2 months ago.
This is going to take awhile. I guess I need to see if someone has the necessary equipment. Or just take to mechanic which is not much of a response
