Check the battery cable ends frequently for corrosion. Corrosion can easily migrate under the cable insulation and cause numerous electrical faults and drivability issues.

2004 Lincoln Navigator Problems
In high dust areas, problems with the EGR system are common. The filter for the EGR solenoid may plug and cause the EGR to activate when it should not; this can cause the engine to stall. The dirty filter should be replaced to correct this concern.
Erratic engine coolant temperature or intermittent overheating can be caused by corrosion inside the water pump. The impeller may spin on the water pump shaft or the impeller may corrode. Either condition reduces coolant circulation resulting in engine overheating.
Prior to jacking or lifting a vehicle with air suspension, you must turn off the suspension switch. The switch is generally located in the trunk or on the right side of the passenger foot well.
An exhaust leak may develop in front of the catalytic converter. This type of leak should be corrected as soon a possible to avoid damaging the catalytic converter.

2004 Lincoln Navigator Reviews
I bought my 04 Nav new in 04 and I have been very happy with it with these few exceptions.
The air suspension on these SUVs are not good at all. Every person I have known that has had one has had problems with the air bags and this makes the pumps run all the time, eventually burning them up. I paid thousands to fix the system twice and then replaced it with a standard system.
Other than that, the emergency brake electronic release went out in 07 and I never replaced it because it's hundreds of dollars to keep me from just releasing it by hand and I can do it by hand, no problem.
The hood paint cracked up like it had the wrong primer or something and I have just put up with it, but, it looks crappy and I should have taken it back to the dealer.
The chrome on the console handle becomes loose and this is very sharp in a place where you are meant to grab and lift up to open the console. I have replaced it 3 times and my wife has cut herself twice on it.
It has 150k on it and it began having what sounds like a valve tap at about 130k and it has become pretty loud, again something that is expensive to fix and I decided to what till it brakes. But, it's so loud now that my wife won't drive it cause she's embarrassed by it.
All and all it's been a pretty reliable decent car and I'd buy another if the economy wasn't so bad. For now, I'll fix what I can and drive it till it gives up :)
I have a 2004 lincoln navigator i notice my air pump keep running,all the time after two weeks of that, one morning my front end was lower then the back, i turn on the truck, and sit there for 15mins the front rose at the normal level, after two weeks of that i took it to the local dealer ship, they told me the air bag rings was bad the cost 489 dollars, when i drove it home i notice my air pump is still running all the time, before making it home my air suspension light came on, then my front end went down i took it back to the dealership they told me my air pump was leaking and it needed to be replace cost 700 dollars, i had a 2000 lincoln navigator with the same promblem i wish ford do a recal on there air suspension, because the cost of the labor is to much.
