Does a brake light switch have a fuse?
If your lights don’t illuminate on either side and your brake light switch is good, then the next thing to check is the brake light fuse. Locate your vehicle’s fuse box, which is usually under the hood or on the kick panel inside the passenger compartment. If it has, replace it with a fuse of the same resistance.
What to do when your light switch stops working?
If the wires aren’t that loose, you can disconnect them from the switch, twist them together with pliers, and use the voltage tester to check if power is running through the wires or not. If it is, the problem is most likely not with the wires, but with the switch itself. In that case, you’ll have to have the entire light switch replaced.
What happens when the brake light switch is not working?
Brake light switch is installed above the brake pedal. Many vehicle systems including Push-Button start, Antilock Brakes and Vehicle Stability Control cannot operate if a brake light switch is not working properly. The brake light switch serves two major functions. First, it turns on the brake lights when a driver presses the brake pedal.
How can I tell if there is no power in my light switch?
The best way to check to see if there is power entering the switch box is with a voltmeter. If you don’t have power in the sw box, then the problem lies somewhere in the circuit between the sw box and the breaker/fuse box. Do you know what else is on the circuit, and have you check those??
Why is my breaker light not coming on?
Switch on the breaker and if the light now comes on, you likely have a bad switch and need to replace it. If the light still flickers or doesn’t come on when you bypass the switch, the problem could be a loose connection somewhere else in the circuit and you’ll either have to do further investigating or call an expert to diagnose the issue.
