The flasher on front (same bulb as corner light) works. Brake light, reverse light, and turn signal on rear all work.

Ok good info so let's diagnose it.
Wiring diagram for lights on your car:

1. tail light
How the power goes:
N7 -> E4x1 connector -> tail lamp -> E4x1 -> W7 ground
I think we can eliminate a bad ground since all other lights work.
Find connector E4x1 (should be behind the passenger side trunk panel)
Disconnect the connector and find terminal number 6
With a multimeter put one probe to ground and the other probe in terminal 6 check if you're getting voltage.
This way we will narrow down to where the problem is.
2. Front marker light
Because your flasher works then we can say that the ground point W10 is good.
Disconnect the right side turn signal/marker light connector.
With a multimeter put one probe to ground and the other probe in terminal 4 check if you're getting voltage.
Terminal 4 goes straight from the N7 relay.
do these 2 tests and then we can diagnose it further.
