Question about 2004 Lincoln Navigator

Air Suspension conversion completed. Converted to Spring/Shock setup. Excellent ride!

How do I turn off the "Check Air Suspension" Warning Light on my dash. I reset it at the display, but the warning light keeps coming on. Annoying. Thanks.

    Thanks, but I don't think the vehicle has a bulb. It's an indicator module on the dash reading "check air suspension"

SOURCE: Check Data Communication Link (DCL)

Look for a missing ground in the circuit. Almost sounds like your missing ground is being sought through other accessories. You will need a ground/power test light - This type lights Green for ground/and Red for power to find the problem.

Start with a schematic

SOURCE: Check air suspension system problem

sounds like one of the rear air bags is leaking and if you get under car and spray with soapy water from spray bottle you can find leak and replace bag or line that is leaking. turning off the pump is not a good idea the rear bags will deflate and cause the car to ride too low and cause damage bottoming out. also if the leak is not fixed soon the air compressor will run too constantly and burn out/wear out and very expansive to replace.

SOURCE: Air Suspension system Problem 1990 Lincoln Towncar

Unplugging the Connector will cause the Check Suspension light to come on as its listed as a fault as it cant run.

But with it unplugged the compressor shouldnt been able to start. If you want to kill the compressor pull its relay from the engine bay. located above the battery.

But i'd suggest correcting the fault as if those bags do pop your going to end up being grounded. as the rear will drop a fair bit!

Most likely you have a leveling sensor that is faulty, dirty, or is loose. Could also be a short in the circuit. You could remove the fuse and/or buzzer for now until the problem can be corrected.
Good luck..hope this helps.

1994 continental. air ride. compressor starts and rear starts to lift, but after 3-4 mins. i get a beep and light on dash says ride control and then she squats in the rear?


When I got my 1994 Continental, it had already been converted back to a coil-spring suspension, and the air-ride system was GONE. You will find that is the case with most of the ones that are still on the road. The air-ride system turned out to be an unreliable, trouble-prone, nightmare for most owners....and it was cheaper to scrap it and go back to after-market coils, than what it was to have a Lincoln dealer fix it. Looks like you're destined to join the club....If you decide you want to have it fixed, and make the car driveable, be prepared to PAY for it.

1997lincolnviiiair ride system in front end is loosing air


This is a common problem for all Lincolns. Since the front rises but can't hold the air, it's a good sign that you don't have any compressor problems. You probably hear the compressor constantly clicking on to try to keep the front end inflated.
The most common cause is a leak in the air spring. It is often referred to an "air bag" which is basically a cartridge that fills and releases air based on the load. The most common repair is to replace the air spring (it's advisable to replace 2 at a time). There is another solution to replace the air spring(s) with a conventional aftermarket shock type spring setup. It's a matter of personal preference. You would still get a nice ride from a conventional shock absorber setup. Although more expensive, I've always preferred to go with the air spring replacement to keep the classic "Lincoln" ride intact.

My 1989 Lincoln Continental air suspension went out is there a replacement spring or shock I can use instead of orignal air ride


Yes, theres a kit that replaces the air bags with shocks and springs and then they give you a small module that connects in the trunk to the air suspension diagnostic connector to turn off the air ride light and keep compressor from running, i,ve found that the price ends up costing the same or more to replace than repair. i have done a ton of these and the problem is the bags leak and sometimes cause the airpump to go bad, theres a web site i use that sells these parts cheap and they work great, start by replacing the bags and then the compressor if needed, the selinoids on the bags are reuseable, now if this car has the front and rear air ride then it is cheaper to convert and i think this car does if its got the v6 engine then it is front and rear air suspension, they sell a kit for 499.00 dollars and comes with struts and springs complete to convert i think just one air strut is 200.00 so it is cheaper to convert .i hope this helps, the web site is get google Airnott industries and then go to the coorect year and make for your car,

Air suspension light came on I turned the car off light went off, then I noticed the rear end of my car was low. What could that be?


It is your air ride suspension. It could be the air bags, the sensors, compressor, wires and many other things. What I did was bought an after market coil spring suspension and converted it from the air ride suspension. The air ride is lovely but costly. It is hard to diagnose that air ride suspension without spending a lot more money then you want. I suggest getting an after market converter kit, but I would make sure it has the sensor plug so that your warning light on your dash goes out....otherwise it will be on forever!

Where are the leveling sensors located on a 2003 Navigator?


There is one at each wheel. here is some info

Vehicle Dynamic Suspension The four wheel air suspension system is comprised of the following components:
  • service switch
  • control module
  • two front height sensors
  • one rear height sensor
  • compressor and drier assembly (includes vent solenoid)
  • air lines
  • front and rear air spring and shock absorber assemblies
  • four air spring solenoids
s3j~us~en~file=ani_caut.gif~gen~ref.gif WARNING: The service switch for the air suspension system must be shut off prior to hoisting, jacking or towing an air suspension vehicle. This can be accomplished by turning off the air suspension switch located in the jack storage area in the rear of the passenger compartment. Failure to do so may result in unexpected inflation or deflation of the air springs which may result in shifting of the vehicle during these operations.
s3j~us~en~file=ani_caut.gif~gen~ref.gif WARNING: Do not remove an air spring under any circumstances when there is pressure in the air spring. Do not remove any components supporting an air spring without either exhausting the air or providing support for the air spring to prevent vehicle damage or personal injury.

1999 Eldorado rear air suspension inflated to max


Converting from the air ride suspension to the passive coil spring suspension will eliminate this problem. To fix your air system you will have to purchase the parts directly from the dealer which means the prices will be severely inflated. Check out Strutmasters website at: http://www.strutmasters.com/Cadillac-Eldorado-Air-Suspension-Rear-Conversion-R-p/-cad-r5ns-el.htm My Uncle converted his Cadillac Deville two years and has only had positive things to say about the effects! I hope this advice was of some help.

Instead of replacing your failed air suspension parts I recommend converting to the passive coil spring system. This is a permanent fix to the problems caused by the air ride suspension. Check out Strutmasters website for the kit that will fit your Range Rover: http://www.strutmasters.com/Range-Rover-Air-Suspension-Spring-Conversion-Kit-p/-rr-03-4.htm. I hope this helps!
