OK 2000 Tahoe brake pedal switch which wire color is hot wire and witch wire color should feed power to brake light when you push pedal down. Also the colors at switch do not match color at bulb!

Get yourself a test light. One side should be hot all of the time and the other should only become hot when the pedal is depressed. Connect to the switched side.

Get a 12v tester and use it to find your hot wire usually the blue wire but it changes depending on where the truck was built.

you need to check for power at the brake light switch.there should be power all the time on one side of the switch and only power on the other side when the pedal is pushed.the switch is under the dash were the pedal is.i think the orange wire is always hot and the white wire is only hot when you push the pedal.(think this is the wire colour)

replace brake light switch, it's mounted just above brake pedal under dash. Small switch w/couple of wires coming from it - easy fix. (common prob)

The flasher does not stop the brake lights from working. Check # 18 fuse in fusebox under lower left side of dash. if it's ok, the brake light switch, on the brake pedal arm is next. light green wire with red stripe is hot if fuse 18 is ok. Depress brake pedal, light green with no stripe should have power. if not, replace brake light switch. If light green wire has power with pedal depressed, combination switch under the steering is next. Remove the cover from around the combo switch {under the steering wheel}. depress brake pedal, light green wire should have power. If it does, pedal still depressed, orange with light blue wire & wire with light green & orange should have power. Those 2 wires are brake & rear turn signal wires. { The turn signal switch should be in the middle, not right position or left. while checking for power in the last 2 wires. Good Luck drvolt.

I don't know the color codes for this but you should have one hot all the time and both hot when pedal depressed. No hot, check fuses, one hot with pedal depressed, switch.

The first thing to check is the brake light fuse,If it is ok check the brake switch under the dash,It is connected to the brake pedal,Check with a test light to see if you have power in one terminal wire,If you do push the brake pedal down and see if you have power in the other wire.If you don't,replace the switch.If you have power,move to the brake light bulbs now,remove the bulb and see if you have power in the light socket,if you do ,replace the bulb,if not you need to trace the wire from the switch to the bulb,remember the color code of the wire at the switch.

Hi my name is mike ! make sure with a test light that you have 0 power to the light back ther ,and if not then take a test light and check down by the brake pedal at the wires that go to the brake light switch ,check all of the wires for power and there may be more than one that has power to it ,do this without hitting the brake ,remember which wire or wires had power to them ,then hold the brake and one of the wires that didnt have power before holding the brake ,should have power to it now because when you hold the brake on it should close the brake light switch and send power to the lights ,if you dont have power coming through that switch when holding the brake pedal down ,then replace the switch .

Probably the brake light switch. It should be located below the brake pedal close to the firewall. When you push the brake pedal down, it activates the switch. The switch can be tested with an ohm meter or multimeter. Also look for damaged or disconnected wiring. Sure hope this helped and good luck.

There is a clip that gets worn on the brake pedal that holds the switch tight to one side. It must be put on correctly or else the brake lights will come on for a split second and then go out when you push the brake pedal down further.
