Tail Light issue.
 

As many of you know I have the sequential turn signal kit. Plug and Play style. My driver side tail light was acting like it was burnt out. So I get out the check and only the inside most light is flashing when the turn signal/hazards or on. So i figured I had a burnt out bulb. But then I went to the grocery store got back in my car and it was fine all lights were working properly. This has happened to more twice so far. I checked the wiring in the back and from what I can tell everything looks fine. Any suggestions on how to fix this? It does not happen often but will it once in a blue moon. Please note it is just the driver side tail light.

loose connection?

yeah checked the connection where it plugs in and it was fine. now I didnt unbolt the headlight to check the wires where the lights are. Ill have to check that tomorrow sometime.

Do you have a multitestor? Very handy gadget.

nope do not.

Sears sells some good ones...with performance akin to the "Fluke" brand the pros use, but for a lot less $$. Also, Sears sells a good book on "how to use multitestors" for around $10, if I recall correctly. Very handy to have for tracking down automotive electrical problems, with one very good section on how to measure coil resistance, etc.

I suspect your problem might be within whatever blinker type switch they use in these sequential light set-ups tho...but even if so, a multitestor could aid greatly in your diagnosis. You could compare outputs between the side that works and the side giving you problems...or maybe a bad ground, or???

I had that happen to me a while back when it had gotten really cold back around Oct.-November and then it hasnt done it again.

Maybe some water or moisture got into the housing and was causing it do the once in a while...
