Chevrolet Monte Carlo Repair Question
Brake lights do not work
Did you check for power at the stop lamp socket when you removed it. if there's power you lost the ground point at rear body harness behind center of rear fascia-7cm from license lamp break out.
Recommend you check it -you probably wondering why the 3rd lite is coming oN it is bcuz the brake lites on the bottom has an open ground wire from S402 to S405 ground point.
In other words it has an open between the socket ground to chassis ground
