Very weird tail light issue

[hokieshane]

I've seen all the posts about the contact points, etc. and I've replaced my tail light assembly so I don't think that is the issue I'm having. My bottom drivers side bulb doesn't work, however it does work if I hook it up to the passenger side wiring. Attached are 4 pics...

1. Left assembly hooked up on left side
2. Left assembly hooked up on right side
3. Right assembly hooked up on right side
4. Right assembly hooked up on left side

This issue has driven me nuts and I haven't found anyone that can help. My last resort is to take it into the stealer as I'm past due for a state inspection. TIA for any help you may be able to provide
