with the park lights on both left and right side are lite. but when the brake is applied the right brake lights up and the left goes out(doesn't light up)
I step on brakes, dashboard light comes on which says stop.
Light is usually comes on, when there is a problem with pressure in brake lines. Inspect the brake fluid level, and check for leaks.
You have stepped on the brakes
A brake light switch is a mechanical electric switch that is set in the off position (open circute) and located in front of the brake pedal. When you step on the pedal and its position changes the switch complete's its circute sending power to the brake light. The brake light switch is protected by a fuse or circute breaker and has no other connection with the operation of the brakes.
Sounds like the brake light switch is defective.Sounds like the brake light switch is defective.
There should be a bracket mounted on the steering column near the floor. This will have a switch in it that is a plunger type. When the shaft of the brake pedal is depressed, it comes into contact with this plunger and activates the brake light circuit. If you "ride the brakes", your brake lights will always be on because of the minimal pressure required to activate this circuit.
THE BRAKE LIGHT IS LOCATED BELOW THE DASH. LOCATE THE ARM HOLDING THE BRAKE PEDAL AND YOU WILL SEE A SWITCH THAT COMES OUT WHEN THE PEDAL IS DEPRESSED TURNING THE LIGHT ON. WHEN THE BRAKE IS RELEASED THE SWITCH DEPRESSES AGAIN TURNING THE LIGHT OFF.
Bad ground in brake light circuit
Check the brake light fuse first. Then check for a bad brake light switch at the brake pedal.
There is no switch to activate or deactivate the brake lights on a 1988 Nissan. The brake lights automatically turn on any time the brakes are pressed.
You need to adjust your brake light switch. It should be located on the brake pedal. Unplug the switch and loosen the nuts to adjust the button closer to the brake pedal.
Check the brake light switch. It is defective or out of adjustment.
