i have the same problem on my 1998 jgc. havent found the problem yet but being this vehicle has separate turn and brake lights, i would suspect a faulty signal converter unit in the vehicle. im trying to locate it to test. will post when i learn more.
Simple fix (very common...): The trailer isn't completely grounded - run a wire from your trailer to the tow vehicle. Attach the wire to a bolt or piece of metal that isn't painted (on both ends) and you should be good! Good luck.
Got a chance to check out my issue with my 98 jgc .found trailer package is fuse protected. i had a 15 and 20 amp fuse fuse blown located behind
passengers kick panel access cover. this turned out to be a simple fix for my problem, worth checking first. the running lights probably were not affected because they are a single signal system and not tied into the converter. hope this helps.
The 4 pin connector should have 4 colored wires. They are: Yellow - Left Rear Stop and Turn Signal Green - Right Rear Stop and Turn Signal White - Chassis Ground Brown - Tail / License and Running Lights If you are matching a vehicle to a trailer, be sure to verify this with a test lamp or meter. Some folks make up their own rules, and the connector could be wired differently from the standard!
sounds like you have a bad turn signal flasher One bulb is bad. The right rear turn signal bulb is burned out
1) I've learned more than anything to unhook the lights before backing the trailer into the water. Nothing like a hot bulb meeting cold water.....but if you believe the advertisements, boat trailer lights should be waterproof and not let water into the space where the bulb is. RIGHT !!!! 2) Now, the other issue that has to do adequate grounding usually needing more just the hitch ball. - inadequate grounding is the number one cause of trailer light problems and cause all kinds of strange behavior (work sometimes, or only when headlights are off, or both sides flash with either blinker, etc.) - try a better ground than the tongue and checking for any corrosion at any of the individual light ground connections (which tend to corrode over time).
I also have a 98 Lumina Sedan with the same problem. I did the full wiring check and finally narrowed it down to the turn signal switch. I noticed that if I signal for a right turn and apply the brakes, the left brake light comes on. The turn signal handle seems a bit loose but the brake lights work if you hold it up briefly (like to make a lane change to the right). Replacement part is GM OEM # 19005031 (AC Delco D6226A) for cars w/o the radio accessory on steering wheel. If radio accessory on steering wheel, GM OEM # is 19005032. It takes 90 min to 2 hours to replace (shop time at dealer is 1.4 hours).
Your remote door opener may be the problem. It may be going bad. Leave the remote home and see if that solves the problem
Vehicle side, Brown, running lights Yellow, left signal/brake light Green, right signal/brake light Black, ground Trailer side, white is ground
Im not sure i under stand your guestion, but it sounds like the trailer wireing is wrong. The wires on the trailer should be wired like this. White is ground, Green is right turning signal,Yellow is left turning signal,Brown is running lights, Black is brake lights. I hope this helps you.
Check ground circuit Check bulbs they are duble filamented one may be burned out Seems to me there is a wire crossed at the harness. I think the vehicle left turn signal wire is hooked up to the trailer tail lights wire. Usually there are four wires at the trailer harness, yellow, green, white, and brown, The brown wire is usually the tail lights and side marker lights, the white wire is ground, the yellow and green go to the left and right signal lights.
POSSIBLY A BADGROUND
If the Avalanche came with the factory trailering package, the trailer lights are separately fused from the other truck lights. Check your fuse panel layout for a 10-amp fuse for left side and a separate fuse for right side turn signal/brake light on the trailer.

Assuming you'll be using the common four pin flat connector; Green is Right Turn signal/brake light Yellow is Left Turn signal/brake light Brown is for Tail lights/Running lights White is Ground You may need a 12volt test light to identify the wires on the truck to identify which ones to splice into. Connect to a good ground and pierce the insulation with the pointed tip to identify.

Bad turn signal flasher.
Brown--tail light.licence plate, and marker lights. Yellow- left turn signal and brake light. Green- right turn signal and brake light. White--ground
Start with checking the bulbs, then the fuses. In most vehicles the brake lights and siganal lights and running lights are separate circuits. If the fuses and bulbs check okay check the wiring feeding the rear of vehicle.
At the right rear light the brake light wire is white. There is a manufacturer installed connector for a trailer lighting kit use located about 12 inches ahead of the left rear tail light behind the plastic panel holding the accessories options. The connector holds an orange wire for continuous power. It also has the white wire for brake lights. It has the dark green for right signal lights, yellow for left signal. At the right rear signal light assembly there is more than one dark green wire.
