I have a 1999 gmc suburban 4x4. All rear lights and license plate lights are not working. All fuses are good as well as all light bulbs. Any ideas what the problem could be?


Sounds like a faulty signal switch.Here's a way to check it,hold the brake pedal down while pushing down on and wiggling the hazard switch.If the brake lights come then replace the signal switch.

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.

1999 GMC Envoy: replaced both GE 3057 lamps in left rear light assembly. Lamps both light. However depressing brake pedal does not initiate brake light. The righ rear brake light does work. The high mount...


The high mount brake light has its own fuse, so check that first. The high mount bulb is generally a stabdard type (there may be more than one bulb) or you can replace with an LED. As for the left rear bulbs not working when depressing brake pedal, check the bulbs again for any spring that may be broken. If the bulbs are still good, make sure there is sufficient contact with the socket. If still not working, have someone check it out further.

Rear Brake Lights not working, 3rd light is working


check the fuse for the stoplights. Even though the 3rd one is working it should be on a different fuse. With both of them not working even after you changed the bulb it would seem to lead to a fuse.
