Tail light keeps blowing? Ugghh! CAMARO

[89s-10Blazer]

I own a '94 camaro and my driver side tail light keeps blowing. I have no trouble with any of the other lights and everything is still factory. I have to change the bulb about every two to three weeks! When it blows, the brake light and the parking light blows! No water is getting in and everything is snug. No loose wires, no cracks in the lens, everything is dry. I haven't touched any wires ever! The radio is factory and there's no alarm installed! No fuses ever blow!

Why is this bulb blowing so often?

Any help to fix this would be great!

sounds like the wiring harness is rubbing against a metal edge somewhere, and every once in a while it makes contact and shorts out. blowing the bulbs. your gonna have to chace the wire. that or put an ohm meter on it, and have someone else try and move the harness at different points and see if the ohms change.

check to see if there is any moisture getting into the housing, it could cause a short or, less likely, the water could somehow contact the buld and the change in temp could break the filament...
