HOW TO REPLACE HEADLIGHT '02 TRAILBLAZER by eagosto

EUREKA! I figured out how to replace the passenger-side hi and low headligts on my '02 Trailblazer. I didn't replace the driver's side, but it doesn't look as daunting as the passenger side. I hope this helps.
  
1.FACE THE VEHICLE SO THAT BATTERY IS ON YOUR RIGHT;
2.REMOVE THE BLACK PLASTIC PIECE THAT RUNS OVER RADIATOR BETWEEN HOOD LATCH AND FAN. IT IS ABOUT 53 1/2" LONG AND HOLDS THE HOOD PROP CLIP. (3 PLASTIC PUSH RETAINERS & 2 SHEET METAL SCREWS);
3.REMOVE THE GRILL ASSEMBLY UNDERNEATH THE PIECE IN STEP 2 BY PUSHING DOWN FIRMLY ON 4 RETAINER CLIPS WHICH RUN ALONG THE TOP. USE A WIDE SLOT SCREWDRIVER. PULL UP GENTLY ON GRILL ASSEMBLY. IT WILL POP OUT. THE GRILL ASSEMBLY EXTENDS UNDER EACH HEADLIGHT ASSEMBLY (HA) AND IT DISPLAYS THE CHEVROLET LOGO IN THE MIDDLE. MY GRILL ASSEMBLY POPPED OUT EASILY AND ALL THE OTHER RETAINER CLIPS ON THE BOTTOM AND BENEATH AND TO THE SIDE OF HA WERE AUTOMATICALLY RELEASED WITHOUT ANY FUSS;
4.ON TOP OF HA SEE ONE TAB (ABOUT 1" LONG)ON THE RIGHT SIDE AND ONE ON THE LEFT (THE ONE ON L IS CLOSER TO THE FENDER);
5.PULLUPWARDDIRECTION ON TABS. THEY WILL SLIDE UPWARD A COUPLE OF INCHES AND WILL RELEASE THE HA WHICH YOU CAN THEN PULL OUT TOWARDS YOU;
6.AT BACK OF THE HA, REMOVE 2 ROUND RUBBER CAPS (ABOUT 4" IN DIAMETER)--ONE FOR LOW BEAM--ONE FOR HIGH. REVEAL BULBS. UNSNAP THE WIRE HARNESS FROM BULB BASE AND TURN BULB 1/4 TURN CLOCKWISE (REMEMBER YOU ARE FACING THE TRUCK)
7.REPLACE BULB(S). #9006 BULB IS GRAY-BASE, FOR HIGH BEAM ON OUTSIDE. #9005 IS BLACK-BASE, LOW BEAM TO INSIDE OF HIGH BEAM.
CHANGING HIGH AND LOW AND REASSEMBLY TOOK ABOUT HALF HOUR. GOOD LUCK. eaachevy

This Guy was right on .. helped me with my 2004 trailblazer..
i had to change my driver side lowbeam lamp
for the '04 ,, it seems a bit easier though ... here are the steps i took : with borrowed input from eagosto(ETA 15 min - for your first time,, next time it may be faster) This also applies to the front turn signal bulbs.
 
Tools needed - large Flat head screwdriver
 
1.FACE THE VEHICLE SO THAT BATTERY IS ON YOUR RIGHT;
2. OPEN HOOD
3.REMOVE THE GRILL ASSEMBLY BY PUSHING DOWN FIRMLY ON 2 RETAINER CLIPS WHICH RUN ALONG THE TOP. USE A WIDE SLOT SCREWDRIVER TO HELP YOU WITH THE REST OF CLIPS (1 IN THE MIDDLE 2 BOTTOM END,2 ON EACH SIDE IN BETWEEN THE HEADLIGHTS). PULL UP GENTLY ON GRILL ASSEMBLY. IT WILL POP OUT. THE GRILL ASSEMBLY EXTENDS UNDER EACH HEADLIGHT ASSEMBLY (HA) AND IT DISPLAYS THE CHEVROLET LOGO IN THE MIDDLE. MY GRILL ASSEMBLY POPPED OUT EASILY AND ALL THE OTHER RETAINER CLIPS ON THE BOTTOM AND BENEATH AND TO THE SIDE OF HA WERE AUTOMATICALLY RELEASED WITHOUT ANY FUSS;
 
4.ON TOP OF HA SEE ONE TAB (ABOUT 1" LONG)ON THE RIGHT SIDE AND ONE ON THE LEFT (THE ONE ON L IS CLOSER TO THE FENDER);
5.PULLUPWARDDIRECTION ON TABS. THEY WILL SLIDE UPWARD A COUPLE OF INCHES AND WILL RELEASE THE HA WHICH YOU CAN THEN PULL OUT TOWARDS YOU;
6.AT BACK OF THE HA, REMOVE 2 ROUND RUBBER CAPS (ABOUT 4" IN DIAMETER)--ONE FOR LOW BEAM (WHITE BASE CONNECTOR)--ONE FOR HIGH (BLACK BASE CONNECTOR). REVEAL BULBS. UNSNAP THE WIRE HARNESS FROM BULB BASE AND TURN BULB 1/4 TURN CLOCKWISE (REMEMBER YOU ARE FACING THE TRUCK)
7.REPLACE BULB(S). #9006 BULB IS GRAY-BASE, FOR HIGH BEAM ON OUTSIDE. #9005 IS BLACK-BASE, LOW BEAM TO INSIDE OF HIGH BEAM.
 
-- NOTE--- if you have small hands ,, you could take off the caps and bulbs without doing the above,, but the connector to the bulb is very short and maybe a bit cumbersome to install the bulb. (again took me 15-20 min,, but now that i know what to do,, next time may just take me 5-10 min) This also applies to the turn signals.

I bought an '06 Trailblazer SS on a year end clearance a couple of months ago and decided to install the Sylvania Silverstar lamps, which I put in my pickup a month ago with outstanding results. I discovered immediately the grill would have to come off to remove the headlight assembly. Its just like the '04 described except the low beam is on the outside and both high and low beams use #9006. I hate popping these plastic pieces apart unless absolutely necessary-too easy to break something. So I took the 53" plastic cover with the hood prop clip off and easily replaced the lamps by reaching down and removing the rubber covers on the back of the assembly. A pen light was helpful. I'm 60 with stiff hands, so I think most can do it this way and not mess with the grill and headlight assemblies. Just be careful not to touch the glass on the new lamps, or if you do, be sure to wipe them off with a clean, dry rag. These things get blistering hot and a fingerprint can cause an excessively hot spot, causing the lamp to burst. Good motoring to all!

The suggested method of accessing the rear of the headlight assembly to change the bulb works great. I followed iowapack's instuctions and changed the passenger side headlight in 25 minutes. I'm certainly no mechanic and it was very easy, no grill to remove or fenders to loosen!

I wanted to change the passenger side headlamp. Man, I tried to follow the instructions but had a heck of a time getting the front grille off. So, I went another route.
 
(While standing in front of the vehicle, battery to the right)
 
I removed the right metal fender brace that covered the air filter cover. I loosened the front bolt, and removed the back one. This allowed me to "swing" it out of the way.
 
I removed the air filter cover. There are three screws. One in the back, one on the right side, and one in the front-left. The one on the front-left is a little tricky so I used a long screwdriver and magnatized the screwdriver so I don't lose the screw.
 
After removing the air filter cover, I lifted air filter and swung it out of the way. This gave me great view of the back of the headlamp. With one hand, I pressed down on the wire loom that blocked the rubber cover. Just using my hands, I peeled away at the rubber cover to expose the headlamp.
 
With a small quarter-turn I removed the blown headlamp and reversed this process for reassembly.
 
Took all of 10 mins. I'm sure that it would not be as easy for the driver side, as I would have to remove the battery. Hopefully, that one doesn't blow out any time soon. LOL.

I have nothing to add to reply #11 posted above but that his procedure works great on 2003 TB's as well. The clips are a b*%#h to slide back into place however!!!
