    Not sure why air suspension light is on
     
    • J and K AUTOMOTIVE TOWING AND REPAIR
      # A Lincoln Town Car's air suspension uses a small, separate air compressor under the driver’s side left fender well, and air lines run to the air bags. On top of each air bag is a electrical valve that serves as a relief valve that allows air to be exhausted when activated. The valve 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 because of an increased load, the arm is pushed up, turning on the air compressor and filling 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.
      Air-Suspension Switch
      # 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. If the fuse is all right, make sure the air-suspension switch in the trunk 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.
      Switch Terminals
      # Turn the ignition key with the engine off, and 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 with 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.
      Check for Power
      # Put a floor jack under the axle and raise the axle so 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

    How to take off rear shocks

      Nasty job in the driveway. Usually have to disconnect the lower shock mount first and then bend the shock back and forth to snap it off at the upper stud.

      Raise the RF tire off the ground and see if there is any excessive looseness or sound when you spin it by hand. maybe a bad wheel bearing, loose caliper, missing caliper mounting bolt. Recreate the noise, that is key and you should be able to.

    I am hearing a humming noise comparable to loud tire noise coming from front of vehicle it is loudest while coasting.
    I am thinking it may be a wheelhub bearing, I have replaced the tires so i have ruled that out and replaced the brakes recently. I am wondering can a bad bearing produce a deeper humming noise rather than a squeeking or grinding noise. That is the only reason why I ...

      I may say no for the humming noise for the bad bearing. Humming can be cause of your bad accessory belt or alternator belt; a loose belt can also cause you this. Inspect the belt for loose tension, cracks or worn alternator bearing and then replace parts if needed. Check also your tire pressure maybe low; it can produce a humming sound while at high speed.

    Can I replace the lower control arm bushings only or do I have to replace the entire lower control arm?

      Yeah you can replace the bushings only. Im assuming your control arm is in pristine condition (not bent or anything like that)

      Take your pic, but Moog is good enough for me.

    Is there a master reset for the air suspension?
    The truck sat for about 6 months and the rear went down and the pump won't kick in to raise it back up.

      I don't think there is a reset but there is a fuse. Check it.

      If yanking it doesnt do the trick, sounds like your release mechanism is damaged. Dont fix it yourself, bring it to a mechanic or dealership.

    How to check air pump for air ride 97 lincoln continental
     
    • wrench head
      10/12/2010 wrench head
      When I am troubleshooting the air pump for the shocks, I always start with the fuses and relays.some of the relays and fuses wear out faster with heavy use compared to bsay your cruise control and ABS relays.After you check those then check the connection at the pump for bad wires and/or connections , if everything this far checks out good ,then you need to check your switches at the rear or all 4 corners if you have a complete air ride control system ,they will have a mount with a control rod going from the switch to a mount on the axle housing to automatically turn the pump on to level vehicle.If no switches are bad ,then the pump is bad and needs tobe replaced

    How do I install a tie rod end. I got the nut of the bottom, but the tie rod end won't separate from the spindle assy.
    Mileage- 161,000 When driving at highway speed and bearing left the car has a slight shimmy. When jacked up the wheel can be moved slightly from front to rear. This is, ofcourse, the left tie rod end. Could it possibly be something other than the tie rod end?

      You can use a puller, a pickle fork, or rap the joint with a hammer. It could also be the tires and wheels.

    Air suspension light on
    is on after half hour running. when engine shut of and restarted takes half hour to come back on. car does not seem to be lower but light on bothers me. what do i check??

      A professional shop level scanner has to read the air suspension fault codes to proceed with a diagnosis. There is nothing that you can do without knowing the code other than to go under the car with Windex and spray the air bags and look for air bubbles forming on the surface (foams) of the rubber air bags, especially where the air bag rolls on to itself and where it appears that the rubber is dry and cracking. The light can come on for many reasons. One reason is if the car does not attain the proper height in a specific amount of seconds after the compressor turns on for leveling. The air bags are known to develop leaks.
