tail light help

Ok 91 4x4 wit a 4.3 is havein some probs. Ok the left turn signal and brake lights works untill i turn on my lights. Then they dont work and alls that works is the tail light itsself. Ive already been pulld over twice by the cops. Does anyone know what this is and how to fix it? Also the right tail light is fine and works like it should its only on the left. Thanks all Ken

I'll assume you've check the fuses-Flasher-bulbs?


Then they dont work and alls that works is the tail light itsself.

Does the brake light work while your headlights are on?

If the turn signal/emergancy flashers are working, you could have a problem with the bulb plugs themselves. I had the lights on my old nova go out once while a policeman was right behind me. I turned my signal on and was working till I hit the brakes and "poof", no signal and no running light at all on the left side. Just the turnsignal indecator in the dash burning constantly. Needless to say I got pulled over. :angryfire Come to find out it was the plugs that you insert the bulbs into. They just went out. Got some plugs from a salvage yard and just spliced them in. But use a test light to make sure the wireing isn't working b4 you just go changing the plugs. Just test the wires and if they are not working properly, use the test light to trace the problem back to the problem.

Ok ill try that and now nuthing on the left back side workds but the tail light its self when the headlights are one. It may be the plug because it looks a little scorched on the outside around where the bulb goes. One more thing the steering column moves up and down could that have anything to do with it? I just moves a little up and down not a whole lot.
