I've been dealing with a tail light issue on and off for about a year now and I can't figure it out.
It is intermittent, happens about about once a month, no rhyme or reason. Goes away on its own but comes back.
On the drivers side tail light - the red running light will quit working ( blinker unaffected). i'll get the warning light on my dash.
i've tried swapping in a different tail light housing, i've also cleaned the ground cables where they all screw to the body around the antenna motor. Didn't fix it. This is a clean car, no corrosion or rust.
Last time it happened, I used a multimeter on the pins of the tail light plug and I was not getting power at the pins. So it is something upstream in the wiring.
What other body grounds am I missing here? Seems like a corroded connection I just cant find it.
