Brake lights not working. Come along as I show you diagnose and repair no brake lights on this 1998 Chevy Lumina I will also show you how to replace the turn signal switchHere are s. The circuit for the brake lights may work alongside the turn signal in other car models. If this switch is faulty or damaged the brake lights may not work.

And on most vehicles the brake light system is usually a simple circuit that includes a brake light switch the light bulbs or lamps a fuse and the wiring that connects these devices. I thought the fuses were misfired and the bulbs were damaged. Have a helper hold down on the brake pedal the remaining working brakes lights should be on.

Well I have had this problem in a 2011 F-150 Platinum. A quick test is to try the emergency-flashers on vehicles that use the brake lights as flashers. One of our readers writes that his brake light and the turn signal is not working on one side.

Study the wiring diagram and locate the wire that connects the turn signal switch and the brake lights. Of course it can be hard to tell if your brake lights arent working. Use a test light to probe each of the brake light sockets feed wires.

Also there is a trailer light harness on the vehicle check at that connection or actually remove the trailer light harness as some have a built in converter that can cause weird issues also. No ground would indicate a bad ground connection or a problem with the wiring on the ground side of the circuit. One of them should light up.

If you cannot find power then access the opposite light that is working and probe the wires until power is found to confirm the test light is working. If it too is not working the brake-light switch a bad fuse or an unplugged harness is likely. When your brake lights dont work it is usually because of a blown fuse a worn-out or broken brake light switch or a burned-out light bulb.

Since the bulbs share more of the same circuit components lack of power indicates a problem in the power side wiring. Whats the solution to this problem. Brake lights will not come on.

If they are drawing too much power then switching to LED lights will solve that problem because they draw a fraction of the power compared to incandescent lights. If bulbs bulb sockets fuses and brake light switch all appear to be good the fault is probably the turn signal switch. The brake and signals light was not working on the drivers side.

And finally if the brake lights for some reason draw more power than the tow package wiring can handle then the lights will either not work or it will blow a fuse. This is a quick video I made to help people with their brake light problem this video will work for any car the has combined brake light and signal light.
