Head lamp doesn't work

Took our 2004 Chevy Trailblazer to a local mechanic to see if the bulb needed replacing, but he said he tested it and there is no electric going to the lamp. Is this expensive to correct?

    i had the same problem just last night with my blazer. both of my lowbeams did not work and i had to drive home with my fog lights on. I was reading some other problems others have had and one person on her said to switch relay #45 with #46 and so I did and they both work now you might try it.

It all depends. You need to trace it back to the fuse and switch. A switch is cheap, the harness that the switch plugs into is cheap but you have to pull one wire out at a time and replace them in the exact same slots. The fuses are cheap and wire is cheap.
Whats not cheap is paying someone to track it down. So if you feal confident witn multimeter. Then its some what easy and very cheap to fix.

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. OWNERS SHOULD CONTACT CHEVROLET AT 1-800-630-2438, OLDSMOBILE AT 1-800-630-6537, BUICK AT 1-866-608-8080, OR GMC AT 1-866-996-9463. Potential Units Affected: 871473 Notes: GENERAL MOTORS CORP.

2004 Chevy Trailblazer misfire with codes P0300 and P0410


DO NOT go back to this ripoff artist, he either doesn't know what he doing or is taking you for a ride.
Misfires are usually caused by bad spark plugs or coil packs. Find another mechanic.

2004 Chevy Trailblazer Brake Light


I would start by trying another bulb. Even though the brake and tail light share the same bulb they actually are powering different filaments inside of the bulb so you can have a tail light filament that is working fine and illuminating properly but have a burned out brake light element that won't work at all...all inside the same bulb. Not uncommon at all to see this problem and these bulbs are pretty inexpensive.

I have a 2004 Chevy TrailBlazer that just developed a problem with the left turn signal. The left turn signal indicator on the dash is blinking rapidly and the tail light turn signal is out. I change out...


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

Need instructions for replacing right head lamp for a 2004 Chev trailblazer


You have to remove the holder clip for the grill, plus remove a few bolts holding the headlight assembly to pull the headlight away far enough to remove the bulb holder. You can try to squeeze your hand in there to get to it, but you'd have to have small small hands.

Head lights can be a pain at times but before jumping to conclusions... Have you taken the low beam bulbs out and checked the continuity on them...
The filaments could break and then make a short term contact causing your right lamp to come back on.
Check the bulbs with an ohms meter first before searching for more difficulties.
