Question about 2004 Chevrolet TrailBlazer

2004 trailblazer left brake light

The drivers side brake light on my 04 trailblazer doesn't seem to respond when breaking. The bulb turns on when the lights turn on, but unlike the center and passenger side brake lights, the drivers side doesn't get brighter when when the brakes are engaged.

I have already checked the fuses and I called chevy to verify there was no active recall on my truck. Any ideas as to what it could be?

U have to replace the bulb. There are two wires in the bulb to make it light one is for running lights and other is for brake so just pull it out and see if one of the wires is broken inside. lights are only a couple dollars. good luck

Replace the bulb, the bulb is a double filament bulb and the one that makes it brighter has gone bad. You may want to replace the passenger side bulb also since it's common for both bulbs to go bad around the same time. Try replacing the bulbs with LED bulbs, the LED bulbs last a very long time since they generate no heat at all and have no filament. Rear Turn Signal Light Bulb Size: 3157LL
Tail Light Bulb Size: 3157LL

Thank you for using fixya and keep me posted if you have any other questions.

If the bulb is good the most likely cause sould be the tail lamp board the the bulb plugs into. last i looked the boards were fairly cheap at autozone and easy to change

03 Chevy Trailblazer left rear taillight will not work. Brake light, back up light & turn signal all work. Right rear all work. Replaced bulbs, switched sides, still nothing.


There was a recall on this, see your local Chevrolet dealer.... Recall Date: NOV 01, 2004 Model Affected: 2003 Chevrolet Trailblazer Summary: ON CERTAIN SPORT UTILITY VEHICLES, VIBRATION AND HEAT MAY CAUSE THE TAIL LAMP/STOP LAMP BULB TO LOOSEN IN ITS SOCKET. IF THIS OCCURS, THE BULB MAY FLICKER AND EVENTUALLY BECOME INOPERATIVE. Consequences: AN INOPERATIVE BRAKE LAMP WILL NOT CONVEY THE DRIVER'S INTENTION OF STOPPING TO DRIVERS IN FOLLOWING VEHICLES, AND AN INOPERATIVE REAR TURN SIGNAL LAMP WILL NOT CONVEY THE DRIVER'S INTENTION TO TURN TO DRIVERS IN FOLLOWING VEHICLES. BOTH OF THESE FAILURES CAN INCREASE THE RISK OF A CRASH. Remedy: DEALERS WILL INSPECT THE TAIL LAMP/STOP LAMP ASSEMBLIES, AND IF NECESSARY, REPLACE THEM. THE RECALL BEGAN ON NOVEMBER 22, 2004.

2004 Honda Pilot, right rear brake light doesn`t work. I know it`s not the light bulb because it works for the turn signal and hazard lights.


Chances are that is the bulb. Its a dual filament bulb. The brake portion of it is burnt out. try swapping it with the left side and see if it works then. If it works, get a new bulb.

I'M HAVING PROBLEMS WITH THE BREAK LIGHT NOT WORKING, HAVE CHECK THE BULBS, FUSES, RELAY SWITCH ALL SEEM TO BE OK, STILL WILL NOT WORK. THE TOP BREAK LIGHT IS OK. WHAT ELSE SHOULD I LOOK FOR? THIS...


If the top brake light is working, then the brake light switch on the brake pedal is ok and adjusted properly. GM had major problems with the circuit boards on these....check for power at the circuit boards with the brake pedal depressed.
Also,the brake/stop lamps are wired thru the Turn Signal switch which on this model is the multifunction switch...I have seen this fail many times, it's expensive and not a repair that can be made in a few minutes, takes several hours and a lot of paitence.
Did you check the fuses in the rear fuse box as well?...I suggest you call your dealer or GM direct and see if your vehicle falls under any of these recall notices---i bet it does. If the recall repairs have not been made, then they will do for you at no cost. You will need to have your VIN number ready when you call. Below is a brief description of a recall notice.

The Trailblazers have a common problem with the printed circuit boards in the tail lamp housing.
Unplug the tail lamp housing at the wiring connector and test for power with a test light. ( With turn signals on) You may have an open circuit in the lamp housing circuit board. Good luck

2004 Chevrolet Trailblazer brake light doesn't work


If the other side is working, then it will not be a fuse problem. more then likely it is a grounding problem or there is a short in the wire. Take a test light and check and see if you are getting a hot wire to the brake light. If it is hot then it is a grounding problem. Make sure that the bulb is in the right way and look for any corrosion where the bulb goes and clean it out.

Mazda 3 tail light on, brake light not on


The bulb actually has two seperate elements in it.
That is why the tail light works fine.

If you take the bulb out you will see the seperate elements.
Change the bulb and it should be fine.
