There is a Fuse Under the Hood called CHMSL. This stands for Center High Mount Stop Light. It should be a 10a Fuse.
01 Yukon 3rd brake light removal......changing the third brake light on a 2001 Yukon is a relatively easy task. First open the rear liftgate (not just the glass). This will expose the two screws that secure the housing of the lamp to the body (it also exposes the connector plug which, obviously, you should unplug). After removing the two screws, separate the rubber housing from the LED lamp itself....and there you have it!...because the third brake light is a sealed lamp the entire brake light must be changed. you can�t just replace the bulbs. ...
You can also try ebay. I just purchased the 3rd brake light for my 2004 Yukon and saved $50 over the dealer for a new 3rd brake light. You can try at an auto salvage yard.
the third brake light is direct from brake light switch no fuse
remove tail light and reach through
The 2001 Chevy Blazer brake lights may not work and the third bake stays on because the current light needs to be replaced. A replacement brake light can be purchased at an Auto Parts store like Pep Boys.
it is in the trunk you just turn and pull the light out of the socket and the light bulb is a 194 i do believe
Could be a bad bulb. The same bulb has two filaments, one for the tail lights and one for the brake lights.
Were and how do you change a brake light switch on a Daewoo Leganza 2001
Brake light on and why
The 2001 Buick Century brake light switch is located beneath the dashboard, on the drivers side. The brake light switch should be labeled as such.
open the hatch and look on the inside of the door jamb there should be 2 screws or 3 screws remove those and pull the light out.
If the brake light fuse is good and the brake light bulbs are good it's probably a faulty brake light switch.
