You will need to take off the front guard to get access to the hinges, but it is a relatively easy job to do...just did my front doors on GU ute and took about 30 Min to do, but makes it easier if you have two people to lift the door back into place

Here is the repair procedure straight from Ford manual, but it doesnt give any information about access problems, I will ask a coworker and see if he knows:

Removal and Installation

1. NOTE: Front and rear door hinges can be removed and installed using this procedure.
   
   Support the front door (20124) or rear door (24630) for service using Rotunda Flexi-Work Table 156-00070 or equivalent.
   

1. Mark the location of the front door upper hinge (22800) or lower door hinge on the front door or rear door and body.
   

1. Remove the door hinge-to-body retaining bolts.
   

1. Remove the door hinge-to-door retaining bolts. Remove front door upper hinge or lower door hinge.
   

1. To install, position the front door upper hinge or lower door hinge to the front door or rear door and body. Install retaining bolts.
   

1. Adjust the front door or rear door as outlined. Tighten hinge retaining screw and washer assemblies to 25-35 Nm (18-25 lb-ft) and remove the support.
   

first thing i would do is remove batteries from your key fobs.one could be "acting out' intermittently and enabaling auto down feature.another possibility is left front door lock cylinder switch doing this.do all doors unlock when you cycle door key switch twice?if not definitely something to look at esp if someone recently tried to slim jim your door.

as wierd as this sounds, where the door meets the car at the rubber seal, rub canola oil or some kind of cooking oil, it does not freeze and the door will not stick to the car. Another problem can be that the check strap, the little strap (usually looks like a little metal bar that comes out the front edge of the door between the two hinges) gets sticky. White grease can help that sometimes.

If you have the door panel loose you should be able to see the plastic clips that are holding that in or a plug you can undo to be able to remove the panel completely. If it has clips you can release them with a screw driver.

Hinge, Door Removal and Installation

1. NOTE: A second person is required if the Flexi-Work Table 156-00070 is not available.
   Support the front door (20124) using Rotunda Flexi-Work Table 156-00070 or equivalent.

1. Mark the location of the front door upper hinge (22800) and front door lower hinge on the front door and body.

1. Remove the front door hinge-to-body retaining bolts.

1. Remove the front door hinge-to-door retaining bolts and remove the front door upper hinge and front door lower hinge.

1. To install, position the front door upper hinge and front door lower hinge to the front door and body. Install the retaining bolts. Tighten to 25-35 Nm (18-26 lb-ft).

1. Adjust the front door and front door upper hinge and front door lower hinge as outlined, and remove the support.

You need a body control computer, which controls the windows, door locks and other items. The new computer will have to be programed by a good imports shop or Nissan dealer.
