Re: Right tail lamp failed
Check all the fuses, if fuses ok, then check the wire at the light connection, the jag is really a ford along with its faults, common fault is the earth on the light and the light bulb holder also plays up

There was a recall on this, see your local Chevrolet dealer....
NOV 01, 2004
2003 Chevrolet Trailblazer
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.
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.
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:
GENERAL MOTORS CORP.

Assuming this has the V6, the 15A PARK LPS fuse in the underhood fuse block feeds constant power to the auto park lamp relay. When the relay closes, 12V power passes through the 10A INST LPS fuse in the right instrument panel fuse block to the panel dimmer switch and then to the five instrument cluster lamps.
If by "rear lights" you mean everything in the rear lamp assemblies, power for the tail lights (running lights) starts at the 15A PARKLAMP fuse in the underhood junction block, passes through the automatic lamp control (ALC) relay and the right instrument panel junction block to the tail filament of the dual stop/tail lamp and the separate tail lamp on each side. The 12 V power for the stop lamps is protected by the 20A STOPLAMPS fuse in the left I/P junction block, passes through the stoplamp switch when brakes are applied, stop filament of the dual stop/tail lamps. That leaves the turn signals and the hazard lamps. Power for the turn signals originates at the 10A TURNLAMPS fuse in the left I/P junction block and is applied to the hazard switch. Switch output goes to the turn/headlamp/wiper switch for selection of left or right turn signals. That switch output goes to the turn lamp. Power for the hazard function begins at the 10A HAZRD LPS fuse in the left I/P junction box and goes to the hazard switch. Switch output is sent to the left I/P junction box to make the turn signals flash. That's it. Post a comment if you need more information.
Your vehicle CANNOT be wired for a trailer without using the converter box. The only vehicles that do not require a converter box are the vehicles that use the stop lamp bulb as a turn signal. Your vehicle is equipped with SEPARATE stop lamp and turn signal bulbs.
To make the converter box work correctly, it must be wired according to the instructions to BOTH the stop lamps AND the turn lamps. The tail (or PARK) lamps DO NOT go through the converter box.
Your trailer uses the SAME bulb for stop and turn - THIS is the reason you need a converter.
The wire color for both your LEFT TURN and your RIGHT TURN are LIGHT GREEN/TAN. Although the wire colors are the same at the bulb sockets, these are SEPARATE circuits and must be wired to the correct wire at the converter box. (LEFT and RIGHT) The converter box will have an INPUT connection for EACH of these.
The wire color for your STOP lamps is WHITE/TAN. The converter box should only have one INPUT wire that connects to this. It doesn't matter which side of the vehicle you connect this wire to. All of the stop lamps are on the same circuit.
The converter will then have only one wire for LEFT turn and stop (usually YELLOW) this is the wire that needs to go to your trailer connector for left turn and stop.
The RIGHT turn and stop will most likely be GREEN coming out of the converter.
You need to check for power and ground. If you dont have a volt meter you can get a good cheap one from radio shack. If there is no power recheck with a known good ground. All the lights on that side share a common ground. Check the sockets for signs of burning or corrosion. There is a plug in the left rear quater panell. If you have no power check the corrisponding wire at that connector. The wires splice togeter just before the connector. So if the other brake/tail light is working you know the problem is after that. Hope this helps. Im sure you'll find the problem.
