From the main window switch on driver side: Open rear left, does not open but i hear a click from rear left door. Same exact scenario when i try tear left. Neither ones open if i try the rear switches instead of the main switch. Front right window opens fine from the main switch or passenger side switches instead. Front left opens fine.

So both rear windows don't roll down no matter what switch you use? Please clarify.

Yes, correct. but I just read somewhere that its common and if you hit the door panel while holding the switch down t may work, one worked now, the other didn't.

Yep, I have seen the window regulators go bad and cause this issue. You can help confirm the issue by removing the door panel and testing for power and ground at the window motor. This guide can help:
