Headlight replacement - 2002 Trailblazer - 2002 Chevrolet TrailBlazer

SOURCE: headlight

Hello robbe.
The lights are changed fairly simple, First of all you have to open the hood and look at the back side of the headlamp, you will see a screw on cap on the back of the headlamp system You may have to take somethings out of your way (Battery) I believe it may have to come out. Always disconnect battery by taking the Neg, off first and then positive, Now you should be able to get at the lamp by turning the lamp cover off counter clockwise, disconnect the wire by pulling tab up and unplugging it. Now you should be ready to remove and install the new lamp. ( Be Careful Not To Touch Lamp Glass With Your Fingers) Only touch the Plastic Touching glass will cause lamp to burn out premature, So that should get your lamp Changed. So I hope that Helps you out robbe. Take Care Bear001

should be 2 small rods that you rotate and pull up on, then the whole light assembly should pull off, giving you access to the bulbs.

Your grille and chrome bar are held to your truck with eight clips. You can see the top clips if you look. First VERY GENTLY!!! start pulling your grille until you start popping those clips out. Keep an eye on your chrome bar, because it is clipped into the headlight. GENTLY pull on the chrome bar at the headlight until the clips come off, then work your way over to the other headlight. The goal is to be take your time and be gentle until you have all the clips released. Set your grille aside(be careful not to scratch it). Each head light has two metal tabs on top of it, the outer tabs are slightly hidden in the fender. If you pull these tabs up, it will release the headlight from the frame of the truck(be careful not to let the headlight fall out and scratch your bumper). Once you have the headlight assembly out, pop off the circle rubber cover on the back of the unit. Your bulbs will be inside there, and make sure you don't touch the bulb when removing it. Just reverse the process when your done changing your bulbs. Don't forget to put the rubber cap back on the headlamp unit before you re-install it.
