2001 996 Carrera 4.\, manual transmission.
Driver side headlight stopped working, I mean no turn signal, no low or HI beams and no Fog Light.
Spent two days working on it but no luck.
Any ideas?

 

make sure it's seated in the bucket fully. I would start by removing and reinstalling. Sometimes it doesn't seat fully but feels locked in. That would cause everything to not function.

 

yes and the "lock" in the seat that the headlight goes into can wear out overtime and not keep it fully seated. I had issues with it loosening during driving a few years back and ended up replacing the bracket/tray that held the light in. Was about 150.00 for the new tray iirc.

 

I have a drivers side bracket if needed.
