turn signal and brake light problem?

[josh young]

Last week the tail lights started acting crazy on my Tahoe. I noticed while driving that the right turn signal indicator on the dash was blinking fast, so I thought well just a bulb! The problem is on the right side, everything on the left side works perfect. The back up light is fine as is the park light, the trouble is the (turn signal and brake light) on the right side. I replaced all 3 bulbs with double filament ones, replaced the tail light circuit board, and replaced the square relay under the dash. Still not sure where to look, truck is bone stock, and hasnt had any wrecks, bumps, etc. etc. to make me think wiring issues, but I dont know:confused2:. Just wondering if anyone has run into this problem before, any help would be greatly appriciated!

Thanks in advance!

fixed

My old man came over, got under the truck and had it fixed in about 30 seconds. Man you talk about feeling stupid, the problem was with the plug- ins under the truck in the rear.

what is a plug-in

Josh, my name is Frank, I am having the same exact problem. What is the plug-in you are refering to? Thanks in advance.

Does anyone know what "plug ins" he's talking about? I hate it when people post up questions, figure it out then never return to help others who may be experiencing the same problem.

Anyone out there know?? AND care to share?

just the connections leading off the light would be my guess

Yeah I was thinking that too, but that wouldn't be "under" the truck?? That's right there at the board behind the taillight lenses....

There's a weathertight T under the back of the truck in the frame on the driver's side. It branches out to the tail lights on both sides.

Thank you! But how do you fix it and what is the problem? Guy said his old man fixed it in "30 seconds". It's definately something to check out but still confusing.

I would open it up and make sure the connection is clean. Close it back up with some dielectric grease.
