Top 20 2004 Lincoln Navigator Questions & Answers

Question edited for clarity. Question moved to model category. How old is the battery? Do you do a lot of short journeys. Put the battery on a 6 amp battery charger for 8 hours. If the battery voltage drops below 11 volts there isn't enough power to run the electronic fuel injection. It is a rare issue. Mine is a guess, but I think it is a good one. It is a big vehicle and has a HUGE electrical and electronics system, plus it is winter which affects batteries and power delivery. https://www.google.com/search?q=2004+Lincoln+Navigator+turning+on+the+headlights+kills+the+engine ..

How do you know the brake light switch is ok ? Did you check (with a voltmeter) battery voltage at the switch. Inspection and Verification

1. Verify the customer concern.

1. Visually inspect the following for obvious signs of mechanical or electrical damage. Visual Inspection Chart Mechanical Electrical
   • Central junction box (CJB)
   • Brake pedal position (BPP) switch
   • Multifunction switch
   • CJB fuse 2 (20A)
   • Circuitry
   • Stoplamp bulbs

1. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.

1. If the concern is not visually evident, verify the symptom and refer to the Symptom Chart.

Look at the existing bulbs. HID bulbs are a a different shape and have a high voltage ballast because the are a high voltage arc lamp. https://www.amazon.com/XtremeVision-2003-2004-Lincoln-Navigator-Replacement/dp/B01DQ1TYHY As opposed to a standard halogen bulb that has a filament. https://www.autozone.com/collision-body-parts-and-hardware/headlight/lincoln/navigator/2004 The light from HID is much brighter and often brilliant white or blue-white.

notify manufacturer about your after market ''valet remote starter'' system like with any remote start system they are tapped into your locking system and can cause havoc or disable it so you can ask them about your problem

Faulty fuel pump return valve causing fuel to drain back to fuel tank , connect a inline fuel pressure gauge start engine , note pressure stop engine pressure could drop a few psi then hold , if pressure drops close to zero replace valve or pump .

There is a fuse on back of the radio , but I’d check all fuses because you’ve got several problems.

You may have a wire broken between the drivers door

Did you clear the code and it came back? Does your shifter lever have excess movement ? if so the shifter tube is cracked and the steering column switches are not completely closed also did you adjust the range sensor for the truck to start? This must be done for it to start

Wild guess! You are pushing the switch in the wrong direction. Fingers crossed.

The mirror fold feature on the Navigator is known to be a flaky design. If someone manually folds a mirror then the entire systems gets confused and will not work. There is a procedure in the service manual to synchronize the mirrors but I have never been able to get it to work. Further adding to the problem is that the assembly is not serviceable. You have to replace the mirror and many sellers will not guarantee the fold feature to work.

First, check the bulb if they are busted. Next is to check the fuse box and locate fuse for either stop lamp, brake light or other label that pertain to stop lamp, they may be busted too. Then, check also the wire connected on the brake light switch. It could be worn out already.

It is located on the inside of the right rear window.

Check the system for air leak.

There are scanners which have a function to diagnose the air-ride system. It will take a more expensive scanner that has this function to do the job. Since some electrical shops charge by the hour, a scanner pin pointing the problem in minutes will save you money. Replacing the correct part will also save money instead of financing trial and error parts buying. Some of the system is activated by the opening and closing of your doors. Parking slope also activates the system to level. The master dump valve for maintaining pressure is located around the bottom front of the front wheel well. While the air system is expensive, overall replacing one component is a lesser expense. If you did not have air ride the vehicle would handle differently. You get what you pay for and maintenance is a cost other people do not pay with plain steel springs. Take your vehicle to someone who has a compatible scanner to read your air ride.

typical dealers response indicates that there is a faulty non-return valve in the system that is passing air when sitting and allow air in and out when compressing I would start by checking the valves at the discharge line at the compressor, working to the air reservoir valves then onto ride height control valves finishing with holes in the air suspension bags them selves yes it work doing the checking but there is no real expense until you find the faulty part and I am sure that it will be less than the quote

turn the sitch back on and make sure it comes up to it height

go to the wreckers/junk yards and get good replacements

well the wav file don't work, always use youtube. as to your car, from the description, it's either battery or starter motor related.
