How to replace the brake light switch on a 1998 gmc sierra truck

Follow the brake petal up to the brake rod. Unplug the switch wire then take the clip of the petal then the brake light switch should slide right off.

sounds like your switch on the brake pedal is bad or the wire between the pedal and the lights

you should be able to find it somewhere around the area of brake pedal under the dashcheers

Hello my name is Israel and I will be glad to help you. Above the brake pedal there will be a small white in color switch with two wires coming out of it. This is the brake switch. You will need to pull the pigtail from the brake switch and then "unscrew" the switch and replace with new one. Connect the pigtail. Adjust the switch so that the brake lights activate with a touch of the brake pedal. Good Luck.

Should be located above break peddel next to steering colume under dash.

Check the switch on the brake pedal, connect the wires to each other and if the lights work then the switch is at fault, if they do not then check fuses, wiring etc.

ther is a switch called a brake lifgt switch that has a pin that is moved by your boot brake pedal arm.
the way it works is: when you press on the brake the brake pedal moves down and the spring in the switch pushes out closing the contacts to your brake lights the switch is located high up under the driver's side of the underside of the dash near or, on the brake pedal support replace or, adjust this switch

if all fuses and bulbs are ok get to the brake switch and see ifits stiff or stuck, if it just has two wires on it you could join themtogether to see if the brake lights come on though obviuosly dont leave them joined.Good luck davelee

i would replace the brake light swtich first its more likly too go bad than the turn signal switch

First, check the brake light switch, and if the high level light is on, the brake light switch is the likely problem. Even if it isn't, the bulbs could be burnt out. Anyway, disconnect the wire harness from the brake light switch on the brake pedal. If the lights go out, replace the switch. To test the light switch, disconnect the wire harness from that (with the switch in the "off" position). Again, if the lights go out, this is the problem. More likely, it is the brake one. This happened on my Dodge twice.
