Hey all,

My 2006 4s with OEM taillights is having an issue where the driver side taillight will not light up with the lights on, the brake light, reverse lights, and turn signals work fine. I have swapped the assemblies, and the same result is given from the passenger assembly on the driver side. The passenger side is working as intended. I attempted to purchase another wiring assembly for the driver side but this did not solve the issue (It was worth a shot, oh well) I've checked every fuse as well

It seems I've narrowed this down to the Light switch in the cabin, as well as the rear taillight module under the seat. However, I am not sure from these symptoms which would be the appropriate fix. Additionally, I am having issues finding the taillight module part number to find a replacement should that be the case, if anyone has insights into this I would be greatly appreciative.

 

Test for voltage path as squirrels and other vermin love to eat Porsche wiring.
