Where is the brake pressure switch? No one seems to know.

Hi there, I am Cam. I am sorry to hear about this issue. Can you tell me the code number please?

Expert:  GM Tech (Cam) replied 1 year ago.

IF this is the c0281, that is the brake switch on the brake pedal. These are inexpensive switches and common for issues. I suggest inspecting the wiring, checking for anything installed into that wiring or chaffed wiring. IF you see nothing you can fix, then replace the switch assembly.
