Town Car Air Suspension

Steps - How To Troubleshooting a Lincoln Town Car!

The Lincoln Town Car's air suspension uses a small, separate air compressor under the driver's side left fender well, with air lines running to the air bags. On the top of each air bag is a electrical valve. This is a relief valve that allows air to be exhausted when activated, and which senses the amount of air pressure within the air bag to keep both sides equal.

These valves are operated via a leveling sensor that is attached to the body of the car and to the rear axle by a movable arm. When the rear of the car drops due to increased load, the arm is pushed up. When the arm is pushed up, it turns on the air compressor and fills the air bags to level the car. When the load is removed and the arm moves down, indicating that the back of the car has risen, the sensor opens the valve on the air bags and allows air to escape, lowering the car.

If the back of the car is low, indicating that the air suspension is not working, and the air suspension light is on, check the fuse first. If the fuse is all right, check the air suspension switch in the trunk and make sure it is on. This switch is used when the car is in for service. Always turn off the switch before lifting the car, because the sensor will think the car is rising and keep the air bag valves open, ruining the rear air suspension.

Turn the ignition key with the engine off. Listen for the compressor to come on while pushing down on the rear bumper. If it does not come on, test the switch terminals for power, using a circuit tester. If one terminal has power and the other does not, replace the switch. If there is power, turn the switch to the off position, raise the vehicle and place it on jack stands in the rear.

Inspect the leveling switch on the axle, making sure it is not bent and is connected. Use an ohmmeter for this test. Pull the electrical connector off the switch. Loosen the arm of the switch from the axle. Test the switch with the ohmmeter by checking across both terminals while slowly moving the arm. There should be no continuity with the arm down. As the arm is raised, there should be continuity. If not, replace the switch. If there was continuity, connect the arm and the electrical connector.

Put a floor jack under the axle and raise the axle to the point where it is just beginning to lift the car off the jack stand. Turn on the ignition. Turn the air suspension switch to the "on" position. Use the circuit tester to check for power at the leveling switch. If there is power, turn the air suspension switch to "off" and lower the car. Access the air compressor in the front, under the hood, and check the electrical connector for power. If there is power, check for a good ground. If both are good, replace the compressor. If the compressor works and the car does not rise in the back, replace the air bags.

Lincoln Town Car Replacing Airbags and Compressor!

The Lincoln Town Car commonly needs air suspension work around 80 to 120k miles. What happens at this point is the bags usually wear out on the bottom part of the bag. You will not to be able to see this wear with the bags in the car, you will have to remove them and fully extend them. Lincoln Town Car Airbags are the same as most airbags, functionality wise. Once these bags rub together at the bottom for long enough, they will eventually wear through the chord, and leak.

So now you need new bags. In most cases people don't know they are leaking for a little while, or if they do they ignore it. You may notice the air compressor running sometimes, as it has to keep adding air as air leaks out of the bags. Eventually the air compressor will fail due to being overworked, in an attempt to keep air in those leaky airbags. So one approach is to check your airbags as you get close to 80k miles. And keep an eye on them so you know when it is time for a new set of airbags. That will save you the cost of a Lincoln town car air compressor, which isn't cheap.

If its to late, I have one other solution for you, that will resolve all your town car air suspension problems, for good. The solution is a Four Wheel Coil Conversion Kit, this will completely replace all your air suspensions parts. Everything from airbags, lines, compressor, and solenoids will no longer be needed. Instead these parts will be replaced with coil springs, which are much more reliable than and air suspensions system.

This can also help with other air suspension problems for a Lincoln. Not just necessarily a town car. For instance, say you're having 1998 Lincoln navigator air suspension problems, you can fix that with this method as well. Air suspension conversion kits are known to be very faulty. They tend to mess up a lot. That is why it is a good idea to invest in a coil conversion kit.

Lincoln Town Car Air Suspension Review

The Lincoln Town Cars air suspension uses an air compressor located under the drivers side fender. Lines run from here to the air bags. There is an electric relief valve on the top of each air bag, that allows air to be exhausted. It senses the amount of air pressure in each air bag, to keep both sides equal. There is a leveling sensor that controls these valves. This leveling sensor is a movable arm that will be moved up if the rear of the car goes down. As it goes up it will activate the air compressor, which will fill the bags to level the car. It will also allow air to escape from the bags if the rear of the car is high.

Here are just a few of the problems you might experience with your 1998 lincoln town car air suspension.

1. The back of your car is low and the air suspension light is on. Check your fuse first. If its not the fuse check the air suspension switch in your truck, and make sure it is on.

2. You took it in for service and it was put on a lift or jacked up. And now the bags are full, and the car rides rough. Well you should have shut the switch in the trunk off before lifting the car. Now you will need to bleed the air out of each bag manual and reset your system.

3. You suspension is all the way down. This could be caused by a leaking or stuck valve or a leaking air bag. If it is a leaking airbag, they will all go down, as the car attempts to level itself. So you will need to watch for the one that goes down first as that should be the one with the leak.

4. Your car goes down overnight, but comes up when started. This could be something electronic or could be a leaking bag. Which will soon cause the compressor to go out.

If you experience these air system problems you have a few mechanical options. You can either opt for the costly air suspension replacement, or you can go with the quality coil system that will not break. We at Air Suspension Reviews recommend the coil spring system. Otherwise you will be spending lots of money to replace your air suspension system that will likely break again. More info on lincolns: 98 lincoln navigator air suspension.
