Question about 2003 Lincoln Navigator
This is my first post on Fixya and I appreciate a lot of the detailed and intelligent people on here.
My air ride started acting up just a few days ago. Last week my air ride suspension was fine. I had the car put on a lift for an issue with a loose baffle in my resonator. We switched the air ride off to perform this diagnostic before lifting it.
A few days later, I was looking at my car outside of my office window and noticed it was sitting lop-sided on an even surface. Upon closer examination, the driver's side front airbag appeared to be at a normal height, the passenger side front air bag appeared to be far too high, the passenger side rear airbag was sitting at a normal level, and the driver side rear air bag was sitting far too low. I assumed that the height of the front was putting tension on the driver's side rear. This same set of circumstances occurred for two days with the check suspension light turning off and on until today.
Today the suspension is acting entirely different. Now the rear airbags appear to be sitting at a normal height and the front air bags are sitting too low, nearly to the point of touching the wheel wells.
After reading many posts and suggestions here and elsewhere, I went out to the vehicle, started it up, and put in drive with the brake on. I used a fixed point just below the vantage of the hood to see if the front end was raising and it was. However, I could feel the car shift dramatically from the passenger side to the driver's side, so I stopped the car and the compressor stopped at that point as well. As I stepped out of the vehicle, I noticed a height difference in the front but wasn't willing to take the chance of blowing out an airbag.
The only things worth mentioning that may relate to diagnosis are the jacking up of the vehicle with the air ride switch turned off from the kick-panel and the weather here is extremely cold- in the single digits.
The compressor kicks off and on as it should. The air ride seems to hiss as I get out of the car as it should. The bags have all inflated at one point or another and held air. Instead of paying the dealer "$150.00" for diagnosis alone, does anyone have an idea? Could it be the control module needing re-calibration?
A relay issue wouldn't allow for all air bags to fill randomly. The compressor wouldn't fill all airbags if it were damaged. A leak in the airbags is doubtful if all the airbags are filling at some point or another. I would've sold myself on height sensors but what are the odds of all four height sensors being messed up at the same time? I feel like I've limited the problem to the module but I could use some second opinions before I go off wasting time and money.
Are there are any obvious checks I can have my mechanic friend run? It's my understand I cannot read fault codes with the suspension without the dealer diagnostic. What can I do to help save some money, diagnose this problem myself, and go to a dealer after that if need be with a solution in hand?
Thanks in advance for any suggestions and advice.
Yea, what Ralph said. These Navigators were just atrocious when it comes to the lifespan of the air suspension. They all seemed to go out within 7-8 years. I'd just go ahead and convert to coil springs and save yourself the future hassle.

I have been having a similar problem. It would take up too much typing to give accurate details. But, again, my problem is similar to the one above with a few minor exceptions. I am in Buffalo, New York area...we have been experiencing freezing temps for almost twom weeks. yesterday I took my lincoln towncar to car wash with underspray and car lifted right up and has stayed up as it should since then. i thing maybe someything was frozen; however i would also like a pic of part. By the way my linconl is a 1997 and i bought it new. never had this problem before.
