Rear-Passenger lights not working

1978 911 SC 3.0

So, my rear passenger side tail lights not working; everything~brake, blinker, stop, signal..whatever you name it, it’s out!

I replaced all but the tiny bulbs, greased and lightly cleaned the contacts as much as I could. Checked the 11 fuse, and seeing as it’s only that entire fixture I’m curious if it’s just the entire fixture likely rotted on the inside even though I’m pretty sure this happened before and I had my mechanic replace it about 4 years back.

Could I check any wiring and where, any assistance is helpful.

Sounds like a ground problem.

Diode.

Have a look at the attached diode on the light switch.

Tomorrow I’ll be checking the two I’ve heard of being related to the tail lights in the trunk..

Do you have any idea of all the necessary locations?

I checked the relay (turn signal) and one prong is burned out, I’ll be replacing it tomorrow.
