Is there an adjustment for the stop light switch on a 99 GMC Yukon. I have replace it and my brake lights still do not work. Park lights work fine.


There is no adjustment. The park lights are on a different circuit than the brake lights.
Do you have a third brake light that works. Its also on a different circuit but works from the same switch. Do your turn signals work. They use the same filament as the brake lights.
Also, the brake light circuit goes through the multi function (turn signal) switch.

Since the brake lights and turn signal lights use the same filament in the bulbs, the brake light circuit will pass through the turn signal switch. When a turn signal is used it cancels out the brake light for that side.

Let me know if your third brake light and turn signals work in the rear.
Also, if youy have not already, check/change the bulbs. The type of sockets those lights are in also get burned so look at them well.

Braking lights and turn signals not working


Did you check the brake and signal light bulbs? If something happened that blew a fuse, chances are you probably lost some bulbs too. that should fix your problem

2002 yukon no brake lights but third brake light works


ed7882 I had the same exact problem and thought it was a fuse or the wiring. Come to find out it was just a blown bulb. They are inline together with the cruise so if one blows it all goes. So change out the lights and that should fix it for you.

No brake lights on 96 yukon


The brake fuse #1 is located inside the truck below the steering column. I am assuming you have verified there is 12v power at the fuse & thru the brake lamp switch (orange wire power in & white wire power out, when pedal depressed) at all times. After the brake lamp switch , power goes (white wire) to the Turn signal/hazard lamp switch & out (dark green wire-rt brake lamp & yellow left brake lamp)

Brake lights dont work untill i turn the lights on, then stay on


Hi, are the tail lights and the brake lights in the same light unit?
If so, there is a possibility the bulbs are in the wrong way. If it is a stop/tail bulb then there are two locating pegs on the side of the metal part. If you look, one is higher than the other which has to locate into the correct slot in the holder.

Another possibility is the bulb is wrong, there are double and single contacts. Check the contact on the base of the bulb is the same as the contacts in the holder.

Brake lights/rear turn signals


I had the same problem with my 1999 Yukon. The electric board needed to be replaced. Rust starts to build up and shorts out or blows the bulb. The dealership charged $73.60 for the part and I installed it myself (Saved $30).

Brake lights not working


pretty common issue with the Tahoe/Yukon is the bulb holder...mine both went out at the same time as well...you can buy the bulb holder at any parts store, most have these on hand. They hold all 3 bulbs (lights, brakes/turn signal) and are a simple replace...most likely will fix your problem!
