My driver side door wont open how do i get it

Sounds like the door lach is sticking
use some wd40 spray the lock and let it sit 4 a while
now since you have the inside skin off reach inside the door with 1 hand and try and open the door from the outside and see if the lock bar moves it usualy pushes down i think on a lach
if it goes up and down with no resistance make sure it is contacting the lach if yes make sure the door is unlocked
somtimes the lock is just stuck
after unlock open the door
push down on lock bar attached to lock then pull up on it if that fails to open door
after that all fails unlock door have friend pull handle and then give the door a good kick from inside just remember not the kick the glass
