Hi....
On chevy .
Your problem is Mising ground. or poor groumd to the Tail lights.
First Check all the grounds on the engine compartment.
Near the BATTERY and the fenders wall.
If you found any one damaged Reapair as need.

But if everything is OK...
Check the connections of the Tail lights Under the BED of the truck.
If you found evrything good.

REmove Any of the Tail lights. APPLY GROUND at the BLACK wire of the Tail light connector and see if make any different. If the lights work ok. you can LEAVE with the Ground.
Or try to find where is the wire cut. or in missconntact.

OK... I hope this help to try resolve your problem.

Thank you for use fixya...

How to fix my tail lights, my head lights work,brake light works and turn signals work, dash do too


Maybe a broken or lose wire. The turn signal and brake lights operate from one wire and the tail lights operate from a separate wire. It is possible that the tail light elements burned out of both bulbs. Pull the bulbs out and check them first.

I have no tail lights when i turn on my head lights


check your tail light fuse, or blown bulbs. Just do a small test before you strip. Put someone in car turn ignition on and just apply brakes, if the brake lights come on means you have tail lights bulbs blown . If you have no lights at all go again for bulbs or fuse.

1970 chevy pickup tail light goes out when putting on brake


Sounds like it might be shorting when applied. have you checked the bulb? If you have a multimeter check power before and during brake application that can help see if your losing all power when brake is applied . If lose of power check at the brake switch.

Brake lights only work if parking lights are off


Yes check for bad ground. This happens a lot of times when grounding is bad, the more bulbs that try to come on loses ground. Sometimes lights will even pull a ground through the opposite filaments on the bulb, resulting in when power is applied to that filament, then all lights go out. Please rate my answer so I am rewarded points for it.

I have a 99 Jeep Cherokee limited and when I turn my lights on my tails don't work but when I apply the brakes the passenger side comes on. I replaced blubs and sockets.


Had a similar problem in mine. When I applied brakes while head lights were on, the the light would go off completely. There is a computer chip in the tail light assembly that tends to go bad causing the light to malfunction. I just bought a new tail light assembly from eBay and now it works perfectly. As easy as putting in a new bulb but you just have to unplug electric terminal from the light and plug in new light once received.

1998 honda accord, with the headlights on the tail lights are on but turn signals do not work. if head lights are off turn signals work unless i apply the brake, if i apply the brake the brake lights work...


It sounds as if you have a bad earth to either one or both of your rear light clusters. If it only happens when you indicate in one direction then that is the offending side.
