If it starts and then dies, check the fuel system. If it runs but will not move check the transmission or a stuck brake system.

The door hinge could actually be broken. The door and hinge are all plastic. When you remove the lower console you can actually feel if the door is loose. There is an aftermarket replacement with metal hinges that works great. Normally you have to remove the entire dash to replace or fix it, but the aftermarket one has you go through the glovebox and cut a hole in the duct to reove the old door and replace it with the new one. (You epoxy the cutout back in to seal it - it's out of side and is totally airtight.) I recommend looking into that.

If you aren't getting any cranking upon turning the ignition switch it could be the ignition switch itself. If that's the case you'll probably need a locksmith to come over and replace it. But check your service manual for more information first. You might need to do some more troubleshooting.

Sounds like a possible crankshaft sensor, when they start to fail the resistance in the sensor gets too high, sometimes will manage to start but as the temperature of the engine (and in turn the sensor) increases so does the resistance in the sensor and causes an engine cutout, once left to cool down the resitance drops a bit and may allow the engine to start again. This would have to be confirmed with diagnostic equipment or by checking the sensor resistance, either way a job for the garage.

Go to ford/lincoln owners. Com and register for free then download your owners manual and then go to roadside emergencies and your fuse box diagrams and fuse values are in there

You may have a broken transmission mount take a look put a jack under the tail shaft out a little pressure on it you see it separate if it's bad ..I've also seen motor mounts cause that on rare occasions

suspect that the starter is failing , we can not fix it . only a local mechanic can

Check to make sure gear shift is in Park. Rock the steering wheel hard without the key in. Try the key...you may have to hold the steering wheel all the way in one direction and try or the other direction and try. Good luck. Sometimes the steering wheel lock does not line up when you removed the key.

There may be a switch operated by the hood. I would check the fuses and relays under the hood.

make sure you don't have an air leak at the springs or the compressor. but you may want to have the air suspension module checked for fault codes. the module itself may be the issue not processing the inputs correctly and mis-leveling the vehicle.

the air ride suspension has level sensors under the vehicle, one of the sensors must be bad making the truck deflate the airbag or inflate it too much. you may need to have someone with a scan tool to access the air suspension module and check for fault codes. you can try turning the air suspension switch off for about an hour to see if the system will reset. the switch is located under the dash on the right side kick panel.

It will only process a "down command" if it thinks all the doors are closed. If you have a bad door switch, it won't lower. Any courtesy lights on with doors closed?
The dealer can conduct a diagnostic scan test and retrieve any codes that will help identify the bad circuit. Did they do that?

Do you have 4 wheel air suspension or just rear?

Assuming rear only:
The system consists of unique rear air springs, the air compressor, air lines, air spring solenoids, height sensor, air suspension control module, attachments and associated signals derived from both driver and road inputs. With these components and signals, the air suspension control module commands changes in vehicle height that are necessary for the load leveling features.
The load leveling feature rear air suspension (RAS) systems shall automatically make adjustments in vehicle height so that the vehicle is always at trim height and constant front-to-rear vehicle attitudes are maintained over the expected load range of the vehicle. Adjustments in height that are necessary to correct height differences between the vehicle's left and right sides for the RAS system shall be restricted to what can be reliably achieved with one air suspension height sensor.
The system uses one air suspension height sensor, a steering sensor, generic electronic module (GEM) and other vehicle sensors to measure driver and road inputs. The system changes vehicle height using an air compressor, two air lines and the use of air springs with air spring solenoids.

Note this section.
The air suspension system holds vehicle height when the rear hatch or any door is opened. The system stores rear vehicle height the moment any open door is detected. The system then maintains this height regardless of the addition or removal of a load. The system will return to its commanded height when all doors are closed or the vehicle speed exceeds 16 km/h (10 mph).

Air Suspension Switch
The air suspension switch supplies power to the air suspension control module. Without the air suspension control module receiving this power, the load leveling system is inoperative and will not react when the rear of the vehicle is raised or lowered. If the air suspension system is disabled by turning off the air suspension switch, a "CHECK SUSP" will appear in the RH corner of the instrument cluster with the ignition in the run position.
--------------------------------------------------------------------
The vent solenoid:
  • allows air to escape from the system during venting actions.
  • is part of the air compressor cylinder head.
  • has a 1,103 kPa (160 psi) internal relief valve.
  • shares a common electrical connector with the air compressor motor.
  • is enclosed in the cylinder head casting, which forms an integral valve housing that allows the valve tip to enter the pressurized side of the system.
  • has an O-ring seal that prevents air leakage past the valve tip.
  • opens when the air suspension control module determines lowering is required.
  • provides an escape route for pressurized air that opens when system pressures exceed safe operating levels.
  • is replaced with the air compressor as a unit.
---------------------------------------------------------------
Air Suspension Height Sensor
One air suspension height sensor is mounted on the vehicle. The air suspension height sensor sends a voltage signal to the air suspension control module. The output ranges from approximately 4.75 volts at minimum height (when the vehicle is low or in full jounce), to 0.25 volts at maximum height (when the vehicle is high or in full rebound). The air suspension height sensor has a useable range of 80 mm (3.2 in) compared to total suspension travel of 200-250 mm (8 to 10 in) at the wheel. Therefore, the air suspension height sensor is mounted to the suspension at a point where full rear suspension travel at the wheel is relative to 80 mm (3.2 in) of travel at the air suspension height sensor. The air suspension height sensor is attached between the No. 5 frame crossmember (upper socket) and the panhard rod (lower socket).
When the air suspension height sensor indicates that the rear of the vehicle is lower than trim under normal driving conditions, the air compressor will turn on and pump compressed air to the air springs. When the sensor indicates that the rear of the vehicle is raised above trim under normal driving conditions, this will cause the air to be vented from the air springs to lower the vehicle back to its trim height level.
Compressor Relay
The compressor relay is energized by the air suspension control module to allow high current to flow from the battery to the compressor motor.
  • A solid state relay is used in the air suspension system for air compressor control. The relay incorporates a custom power metal oxide semi-conductor field effect transistor (MOSFET) and ceramic hybrid circuitry. The relay switches high current loads in response to low power signals and is controlled by the logic of the air suspension control module.
Air Suspension Control Module
NOTE: The 4WAS air suspension control module is used for the RAS system. The internal processor recognizes external circuitry to determine if it is installed in a 4WAS or a RAS equipped vehicle.
NOTE: The air suspension control module is calibrated with information from the air suspension height sensor. A new or exchanged air suspension control module requires a ride height adjustment calibration process to be performed.
The air suspension control module controls the air compressor motor (through a solid state relay), and the air spring solenoids. The air suspension control module also provides power to the air suspension height sensor. The air suspension control module controls vehicle height adjustments by monitoring the air suspension height sensor, vehicle speed, a steering sensor, acceleration input, the door ajar signal, transfer case signals, and the brake pedal position (BPP) switch. The air suspension control module also conducts all fail-safe and diagnostic strategies and contains self-test and communication software for testing the vehicle and related components.
The air suspension control module monitors and controls the air suspension system through a 32-pin two-way connector. The air suspension control module is keyed so that the air suspension control module cannot be plugged into an incorrect harness. There are two sides of the harness connection to the air suspension control module. Each is uniquely colored and keyed to prevent reversing the connections.
---------------------------------------------------
May be a bad module too.

It sounds like your Navigator has a vacuum leak after the Mass Air Flow (MAF) sensor. This could be in the intake air tube between the MAF Sensor and the throttle body or it could be a bad vacuum line, bad/stuck EGR valve, bad DPFE sensor, or intake manifold leak. There are several ways to search for a vacuum leak, but I'm not sure this is something you realy are looking to tackle versus having an idea if a shop is being honest with you.
