Re: 2004 Chevrolet Trailblazer
First face the vehicle so the battery in on the right. Second open hood. Third Remove the Grill by pushing firmly on two retainer clips that are on the top, use the wide slot screwdriver to get the rest of the clips off. Pull up gently on the grill it should then pop out. The grill extends under each headlight assembly any other retainer clips should release when the grill in popped out.
Fourth on top of the headlight assembly you will see one 1" tab on the right and left side, pull the tabs upward about two inches and this should release the headlight assembly. You then should be able to pull the headlight assembly out toward you.
Finally at the back of the headlight assembly you will see two rubber caps one for low beam and one for high beam, the white base is for the low beam and the black base is for the high beam. Unsnap the wire harness from the bulb base, turn the bulb clockwise.
Replace the bulbs high beam on the outside and low beam on the inside.

Check the headlight bulbs first. They have both the high and low filaments, if you have one bulb per side. Some may have a separate high bulb and low bulb. Regardless, the lows can burn out and the highs will still work.
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.
ALTERNATIVE: IF YOU ARE REPLACING THE PASSENGERSIDE HEADLIGHT JUST REMOVE THE AIR FILTER COVER AND PULL PLUG OUR FROM BEHIND HEADLIGHT AND REPLACE. BE CAREFUL HANDLING LIGHT BULB. TO CHANGE THE ONE ON THE DRIVER'S SIDE JUST REACH IN FRONT OF THE BATTERY TO ACCESS THE PLUG AND HEADLILGHT. TOOK ABOUT 5 MINUTES. ENJOY YOU TRAILBLAZER, GREAT TRUCK.
first check fuses and relays that give low beam lamp power if all checks out ok check bulbs youshould be able to see the filliment inside the bulb if its broken replace the bulb. if bulb check ok get a test light and check for power at the wires going to the bulbs if you have ppwer with the light switch on replace bulbs. if no power to the wires going to the bulbs replace light switch.
The daytime running lights run the high beam bulbs at low voltage so it sounds like you need to put the relays back where they were and either replace the low beam bulbs or repair the wiring to them.Also the relay you removed could be defective.
