2012 Lincoln Navigator ProblemsA/C Fan Speed Changing Constantly
The Lincoln Navigator with optional automatic temperature control may have a problem with frequent fan speed changes when using the heater or air conditioner. Normally, the fan speed changes only to maintain a selected temperature, but when the fan speed changes frequently and needlessly, there is an issue with the fan speed control unit.
The fan speed control unit, sometimes erroneously called the blower motor resister, regulates the speed for the blower motor in order to maintain the temperature set by the driver. When it fails, the fan will run at random settings, and the climate control will be inaccurate.
Note: this does not affect the temperature of the air that comes from the vents, it affects the amount of air that comes from the vents.
The repair is simple, and quick. The control unit is located behind the glove box in most models, and removal and installation takes only minutes.
Also note: this only applies to vehicles with single or dual automatic climate control.
The 2008-2014 Lincoln Navigator and Navigator L with manual temperature and fan controls may have problems with the the blower motor only blowing air on certain settings. Most commonly the fan will only run on the highest setting. This is a well documented problem, and is caused by a failing blower motor resistor.
Correcting the problem is straight forward, and requires replacement of the small resistor. The resistor is normally found behind the glove box, next to the blower motor.

2012 Lincoln Navigator RecallsAutomatic Transmission Shifts To First Gear Unexpectedly
The vehicle's automatic transmission may shift unexpectedly and suddenly into first gear while driving, which can result in a loss of vehicle control, sudden slowing of the vehicle and possible transmission damage. Dealers will reprogram the powertrain control module with updated software free of charge to resolve the concern.
Certain vehicles may have been assembled with a transmission range sensor (TRS) that was calibrated out of specification for reverse gear. If this condition exists, the transmission may not properly engage reverse gear and/or if reverse gear does engage, the "R" indicator on the dash or the backup lamps may not illuminate. These conditions increase the risk of a crash or a pedestrian being struck due to the vehicle's not signaling it is in reverse. Dealers will inspect and replace the transmission range sensor as necessary to correct this concern. The Ford recall number is 12C23.
These vehicles may have inadequate welds on the head restraint support brackets for the second row, right side seat. In the event of a crash, the head restraint may not provide adequate protection, increasing the risk of personal injury. Dealers will replace the head restraints as necessary to correct this concern. The Ford recall number is 12C22.
