Hello I have a 2006 grand Prix I recently bought from a guy.. Ive noticed on the dash it says service break apply sensor... My break lights come on only when i make a complete stop. They do not give off warning that im slowing down until im a 0 mph.. In the last month I have spent well over 700$ trying to fix the problem.. I've replaced the
Brake switch-
Brake pedal position sensor-
Body control module-
Checking all wires for short
Another body control module
Plus labor..
I'm so tired of getting the run around I just need some real advice that will help my problem.
Thank you
