Need 02 trailblazer third brake light removal

You usually need to remove the back of the rear seat to remove the package tray.

If your rear brake lights are working, the fuse is good. Check the wiring.

Hi Edward-
The top brake light lens is held on with two size T25 Torx screws. You need a suitable size torx screw driver to remove (and again later replace the assembly) the two screws. Once the screws are removed (do not lose these), you can remove the entire lens assembly. You'll see the wires leading to the plastic bulb socket. The bulb socket twists off the assembly like a bayonet. Once the bulb socket is off, you'll be able to remove the bulb simply by pulling it straight out. Replace the bad bulb by inserting the new bulb and then reassemble your third brake light in the reverse order you removed it. Enjoy!

Hey Stan the man,need your vehicles info.,year,make,model and engine size and Tommy on the spot here will send you a picture diagram of your rear brake assembly.There's a special spring tool you can get at auto parts store to remove and install springs,me got one.

Check your fuses if it isn't that check and see if your bulbs are blown.

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

need to know if your third brake light up high is working or not.if it isn't,you need to check the brake light switch on the brake pedal with a test light,one side hot all the time,the other side should turn hot when brake pedal is pushed.

Hi this is a common problem in the trailblazer line the light brakes stop working on mine but it was really not the bulbs it was the socket I got a recall from Chevrolet to replace all the back lights with a new set but this did not fix the problem what happen is that the socket is not making a good connection with the bulb wires take one bulb out and you will see how the wires are black you can tell they got hot because they are not making a good connection and brake light stop working and to take then out open the rear gate and you will see the 2 screws for the tail light assembly once you get the assembly out you will see a 2 plastic connectors remove then and another 3 screws holding the light bulbs take those 3 screws out and then you can get to the light bulbs what I did to fix this problem I bend the wires in the bulb just a bit to make a better connection and avoid then to get hot once you get a bulb out of the socket you will be able to know better what I am talking about
