#87 of 366 Lincoln Navigator Air Ride
Oct 30, 2008 (2:01 pm)
someone asked if you could bypass the pump to lift rear end from what I tried you can't do it maybe others have a way to do it I even opened the air line and used an air compresser to try and fill it but even that didn't work I had a diagnostic check done and found an EAS fault. the air suspention is inop. received a EAS pump relay fault traced fault to a bad relay and corroded connector. so I'll need to change the relay but do i also need to change the connector as well? or can I just clean it up?

The reason you can't really inflate manually is because there are four separate air spring solenoids on the suspension (one per airbag). These solenoids are activated to open by the suspension control module and essentially let air in or out. This is why when you park and exit the vehicle the Navigator airs-down at different intervals in the front and rear. Each airbag has a solenoid which is there to keep air in or out (depending on the situation). If you try to force air into the airlines you are only going to meet resistance from the closed solenoid.
When you shut the Airride switch off in the rear of the truck, you still cannot open the solenoids. They are electrically actuated and are set to default to the closed position.
Here it is straight from the workshop manual:
The air spring solenoid:
�� allows air to enter and exit the air spring during leveling operations.
�� is electrically operated and controlled by the 4WAS module.
�� is only replaced as a unit (the air spring solenoid is serviced separately from the air spring).
Back to me:
Sometimes you will find that your Door Ajar light is messing with air suspension height levels. That's because it is a factor which determines the height.
Also, if there is a bad connection, a little elbow grease and a wire brush can help.
Hope this helps.
#89 of 366 2003 Nav Air ride trouble
Nov 16, 2008 (5:44 pm)
My 03 2WD Nav goes into "kneel" position (front low) when the ambient temp gets below 65-70 (I live in AZ). It won't go back up until the ambient temp gets back above 70. My local mechanic says his diagnostic computer gets an error code, then the system boots it off before he can get the complete diagnostic. I am hesitant to take it to the local dealer, er- rip off shop. It seems like the dealer will soak me more for the "diagnistic" than the likely repair.
Anyone familiar with a temperature sensitive issue like this?
#90 of 366 98 Lincoln Navigator Air Ride Probs
Nov 17, 2008 (7:45 pm)
98 Lincoln Navigator replaced rear bags and front shocks replaced compressor and dryer compressor runs and leaks down which seems to be normal when car is shut off and ride heights seem fine when driving but seems to ride rough immediatly after I back out of my driveway compressor kicks on and off after bags and shocks are filled but it will eventually stops and will run after a while which seems normal but after driving for around 30 minutes the check susp light will light. If I start the vehicle in the morning the check susp light will also come on after about 15 minutes with the vehicle just sitting in the driveway. When the light comes on the compressor stops running. Does anyone have any idea on what could fix my problem of the rough ride and check suspension light? Please help me

I am having the EXACT same problem, i live in texas and the temperature gets low at night but hot again during the day, the bags barely inflate if the temp is under or around 65 and the ride is terrible. I recently took it to the shop and they changed my solenoids and one of the bags but it did absolutely nothing.... 930 dollars! It is in the shop again right now and i am waiting on another bullshit excuse to give them money. Have you found anything out? I need help and i think this is a weird problem we are having.

I dont know if I found the problem yet. I put both solenoids in the rear and replaced a coupler under the hood on the air line that was leaking and the compressor still runs alot more than I think it should. I havent driven it enough to see if the air bag light will come back on but I will let you know what I find out. After changing the things that I did it seem to ride about the same. I have done everything myself so it hasnt cost me near that much. If you want to save money instead of bringing it to the shop get some soapy water (I used dawn dish soap and water in a windex spray bottle) and follow your air lines and spray them and all connections down tp check for leaks. I also would spray were the air line enters the rear air bag because they are also famous for leaking. Other then that for now I dont know what else to tell you. Let me know what you find out and I will most definately do the same.

#95 of 366 03 Navigator Tire Sensor and Air Suspension Lights
Dec 10, 2008 (4:05 am)
I have a 2003 Navigator and both the tire sensor and air suspension lights are on. The Navigator is sitting on 20's and the air suspension seems to be fine (not slammed to the ground and sits up pretty good). Is there anyway to get rid of those warning signals without spending an arm and a leg?
#96 of 366 leaning to the left
Dec 20, 2008 (2:52 am)
Hi, I have a 2003 navigator. I stopped at one of those side of the road tire shops to get my tires rotated. Instead of jacking the truck up from the sides. He jacked it up under the front and the back. now it is leaning to the drivers side. When i do a systems check on the dash it says everything ok. Any ideas what he may have mess up?
