Hi,

I have looked here for an answer but can't find anything like I experienced.
My Lincoln gave me error C1726. And than he released all air from rear suspension. After few hours I fired it up and compressor was able to pump rear again - so I turned off Air Suspension in computer (i thought it will remain locked like this). When I got back from approx 10 mile drive I turned it off and went do some gardening to relax.. After like 2 hours I had to drive again so I got into Lincoln and and after 2 miles compressor kicked in (air suspension was off in computer - I did not change that). And the air went off... so I drove back home. Now I have fired up Lincoln again and I see he pumped like 2/3 of normal height.
I have bought new compressor, awaiting delivery.
I will not be able to visit Lincoln dealership because there are none in Europe, or at least in Poland
Any suggestion?

 

Is your Navigator 2 WD or A4WD?
To save you a lot of money and aggravation I suggest that you consider a full conversion to springs. I did it and my truck rides great and has no problem even when pulling my 15,000 pound capacity car hauler. I would only use the heavy duty spring conversion.

 

this is 4x4. Air suspension is only at rear. I'd really like to keep it working. My last 03 Navigator was converted to springs so this is last resort for me.

 

Anyway, if I manage to inflate rear air suspension and turn it off in message center, why at some point compressor kicks in and start working and my air bags are deflating? Shouldn't it keep pressure and compressor should not work? Is my thinking logical or this system has some logic of it self?

 

I think you should contact Air Bag Kits & Air Suspension Conversion Kit for realistic answers to this problem. I converted my Navigator's rear to coil springs and still have the air shocks and torsion bars in the front. My compressor stays off until I feel a need to air up the front, which has not happened in over a year. I have the new front coil over shocks on my bench for whenever I have to replace them. Just too lazy to do it now.

 

From your Owner's Manual:


AIR SUSPENSION SYSTEM
The air suspension system is designed to improve ride, handling and
general vehicle performance during:
• Certain road conditions
• Steering maneuvers
• Braking
• Acceleration
This system keeps the rear of your vehicle at a constant level by
automatically adding air or releasing air from the springs. If you exceed
the load limit, the rear air suspension may not operate. The air
suspension system will stay active for 40 minutes after the ignition is
turned off to accommodate any load changes. (The air compressor may
run when the vehicle is off; this is normal.)
The air suspension system can be enabled or disabled through the
message center. Refer to Message center in the Driver Controls chapter.
If the system is off, the rear air suspension will not operate and will not
raise (pump) or lower (vent) while the vehicle is not moving. However, if
the system determines that the vehicle is low or high and needs to make
a height adjustment while driving at speeds above 15 mph (24 km/h), the
system will pump or vent as required. Normal vehicle operation does not
require any action by the driver.
On vehicles equipped with air suspension, turn the air
suspension and the ignition switch off prior to jacking, hoisting
or towing your vehicle.

I think I know what the problem is. I have taken out fuses from air bags solenoids (I think they are responsible from deflating of the bags) and I managed to get them inflated by compressor. I have turned off Air Suspension in message center and from what I see (2 days observation) the air is still there. It seems compressor is weak and cannot fully inflate air bags. Previous owner replaced compressor with the one from Explorer which he said has the same parameters. I have bought new proper compressor, it should arrive in few days, when it does I will replace it and put al fuses back, turn air suspension and see what happens..
