well late last night i was cleaning and spraying lube on a few of the moving parts, but i wasn't able to finish up. so far still no luck in getting the door to stay closed. it does seem like the latch mechanism is stuck in the open position and not latching completely closed after shutting the door. if you just push on the door gently from the inside it doesnt open, but if you put all your weight on it, it opens. same from the outside, if i dont use the door handle and just pull on the door with the window down..same result. i'll investigate more after work, thanks for all the help and keep the suggestions coming
also i dont think the mechanism is doing anything when i pull the handle. i hear a noise of the arms inside the door moving, but i dont believe the circle latch on the outside moves. i did not try this however after removing the door panel...is the circle latch on the outside of the door supposed to move when you pull the door handle?
