2006 Chevy Trailblazer Rear Tail Light

My guess is one of those lamps is burned out, therefore not sending current to the next. My second guess is that the license plate light is last in line, so I would start with the left tail light

The tail light fuse is under the rear seat on the drivers side.

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.

Brake light problem - if bulbs and fuses (#34 and #43 in rear fuse panel) are good, then only other possibility are the circuit boards where all the tail lights are located.

Noise coming from rear is the mode control actuator in the rear HVAC unit, it is trying to move a stuck blend door.

tail light is seperate filament inside the brake light bulb- change bulb

Most of the time you can simply remove the tail light assembly from the car pretty easy and just a few screws. If it sdoes not have the screws going through the front of the housing then its rear mount and must be done by lifting the tailgate to get access. Once in the vehicle you should beable to remove the plastic housing covering up the assembly from the inside. Remove the 3-4 screws or bolts and the tail light assembly. Install the new one just the reverse. Pretty easy just take your time.

Took my Trailblazer to dealership. They replaced both rear tail light socket boards (these are plastic parts that house all of the rear lamps/bulbs and attach to tail light housing) They advised the sockets in the boards have a tendency to go bad. Everything works just fine. Cost of each part was approximately $29.00. Easy to replace yourself and save the labor.

Blinker too fast, the same side blinker light bulb on the front (or back) is burned. Check the fuses for the rear lights. You might have a light bulb filament stuck.

There was a recall on this, take to the dealer and they will replace the whole socket on this.
