Sorry it took me so long but here is a quick walkthrough of what to expect. NOTE : The removing plastic shield in the second picture might be optional now that I know how it works...so don't remove it unless you need to vent =P
Here's the fun part, you have to reach behind the shield and feel for the mechanism that you'll need to move. Since it sounds like the same problem as mine, more than likely your actuator is weak and there is rust and gunk keeping the mechanism from moving freely. I think I used a small but long-shaft flathead to move it. The mechanism is probably stuck in the lowered position which is why the inner lock is in a halfway state because it's hitting the tab that's supposed to unlatch the door. You have to push the mechanism up and the inner door lock should fully move to the unlock state. Pull the door handle and grab a beer (or in my case some jack)
Here's a further breakdown
This is where your problem is, the red lines are the rod for the door handle. Pulling the handle brings the red lines down to where the green lines are, and the spring in the upper right is "supposed" to return it to default. The rust/gunk prevents it from returning and gets stuck in the green portion, and when moving the lock/unlock switch, it just hits the latch to its left.
once you have it out of the door, scrape the rust and gunk off and apply some lube at the orange arrows (I used white lithium grease) so that the metal wont stick again.
I want to change out the electronic actuators but I don't know the part number so if you find out let me know =) hope this helps and good luck to you!
