Stuck front passenger door

The front passenger side door will not open from either side. It happened once before and someone got their arm in there messed with something and it came open. I have recently bought this car and the door has worked fine up until two weeks ago. I cannot get the door panel completely off nor do I have a lot of room to work or even see. All of the rods are hooked up and unbent everything feels and sounds as though it is working properly yet no matter what it will not open. The window goes up and down the door locks actuate properly and you can cycle the door lock with the key with no problems. Aside from painting it orange and putting a flag on the top and 01 on the door what do I do?
