2001 F-150 supercab rear doors stuck

I am unable to open either of the rear doors on the pickup. When I pull the door handle, it partly unlatches, but not fully. It appears to me like the bottom latch is totally released, (The door jiggles more on the bottom) but the top one is only partly releasing. I have been able to remove all of the interior trim, but can not figure out how to release the top latch from inside of the pickup while the door is still closed. So first problem, how do I get the doors open, second problem once I get the doors open, what do you think is causing the doors not to unlatch? Any help would be appreciated.
