97 Honda Del Sol S - Earlier this week, I noticed that when I unlock my drivers side door, it seemed to unlock but then wouldnt open when I pull the handle. I give it a few tugs and it eventually opens up. As the week went on, it started to get more and more stubborn. Now when I unlock it, it wont open at all! I have to go in through the passenger side and open the drivers door from the inside.

I took the door cover off to see if there is anything I can figure out and there really isnt. I sprayed some WD-40 on everything but that didnt seem to help anything. Suggestions?
