How do I replace Brake light switch?

you can use one of the wires from either brake light and make yourself a good ground in trunk and running the two wires to you light switch. be careful where and how you run wires around the trunk hindges as you do not want them to become pinched and short out as that is a safety issue and get you pulled over. always solder and heat shrink all splices and wire to wire connections, if you dont you will hate your self later as wire from front of car to back of car could then need to be replaced.

this may sound crazy but change the bulbs in the light that is up by spoiler and im sure the lights in dash will go off. the dash light and the rear spoiler light use the same ground. let me no if it worked or not.

Could be both bulbs have burned out at once. Or could be the brake light switch. The third brake light and the normal brake lights operate seperatly. Or could be the wires.

I bet it is a ground disconnected or a bad fuse I really think it is a ground you should look up a diagram

This is a simple bulb replacement.Simply pop off the access cover(if you need to) then twist the bulb in a counter-clockwise motion to remove it.Install is opposite of removal.I hope I could help, rate me accordingly, Thanks.

Check your brake light switch at your brake pedal make sure that you have power coming in and then going out with pedal depressed if that is ok check for a faulty turn signal switch the brake lights run thru the switch on the hazard circuit.

Flasher module (under dash by left leg); possible fuse in panel driver side dash by door; possible relay in power center under hood on driver side by brake booster.

1. check brake light fuse 2.check brake light bulb 3. check to see if brake light switch is getting power

get a manuel from an auto parts store. in this manuel it will have etm(electrical troubleshooting manuel) it shows the brake lights and wires colors of wires. trace the wire color from the fuse using the diagram. purchase a test light from wal mart to see if your wire has power. if it does there may be a bad connection or component but hte etm shoud show you what components are on the circuit.any questions email me at [email protected]

This is usually caused by a defective multifunction switch, see it quite allot, the clue is the 3rd brake light, it is on a separate fuse and does not run through the multifunction switch on the steering column.
