1997 Lincoln Town Car. The anti theft system goes off at all hours with nobody around the car. This happens several times a week. You can shut it off by just clicking the door unlock on the remote. Whats...

Hello, I had the same problem when my Lincoln was new. Sometimes the battery starts to short out internally and it triggers the alarm. The Dealer put in a new battery and the car was fine from then on.

You also could be having a problem with the AirRide. Some will compensate to keep the suspension from bottoming out and when the battery gets low enough, it will trigger the car Alarm.
You could leave yourself a note on the car seat and open the trunk and shut off the AirRide when it is parked as a test.

If you come out and the suspension has dropped, you will know the AirRide is to blame and act accordingly. Use your reminder note to avoid driving without the suspension being turned on.

Have your battery tested in the meantime. Autozone, Oreillys, and Advance will test it free and scan your car free too!

98 expedition air shock pump by pass help is there one if so please explain the back end is down and pump is not working

Hello, Check your fuse panel and the Airride switch in the cargo area. It is usually next to the fuelpump safety switch.

Here is how the system works. The vehicle is suppose to stay low for loading and for passengers to get in and out of the vehicle. Every opening (Doors, Rear cargo lid) has to be shut before the AirRide pump will work. Then the pump will work and level the vehicle.

For the doors, it uses the doorjam switches and there is a jam switch in the cargo area opening too! This switch may look more like the one on a refrigerator or can run off the hinge mechanism. For the most part, the door ajar warning will tell you there is a problem in the openings.

After the engine is started, a Relay will power the pump. It is probably your problem if a fuse has not blown. Check with Autozone or similar for an Airpump Relay. The Air release vent Solenoid is a different part and not your problem. If the vent Solenoid was stuck, your pump would run and the vehicle would not raise.

I hope my Solution is very helpful in fixing your Expedition. There is a Diagnostic plug which requires a better Scanner to read, but it is quick and accurate. You would have to call around for Service places having the special scanner for this job if the Relay does not fix your problem.

Hello, There is one cheap and simple way to find the problem and if you do not, the next best thing is a Dealer or Repair shop with a certain scanner needed to read the AirRide diagnostic plug.

There are several TSB's #03-9-2 and #03-7-9 which concern the AirRide. Contact a Dealer with your Vin# for what may be a FREE repair.

Or you need to mix a soapy solution of water and soap in a spray bottle and go under the truck while the AirRide is active. Then spray the suspension bags, the fittings on the bags, and on every air line you see and work your way to the front compressor. When you hit the bad spot, that will be the leak or part that is bad. Since you are losing air, you should not have built up pressure. Still, glasses or Goggles are advised.

There is usually a Master vent valve on the drivers front undercarriage. This part lets all the air out of the system. If you have a "door ajar light" on, then you have a doorjam or cargo door that is not closed or the jamswitch is bad. The way it works is the jamswitches let the Vent valve know the doors are closed and its time to raise the truck. If any single opening on the truck fails to say it is closed, the vent valve will not retain air.

If you go to a Repair shop for this, the diagnostic plug will report any missing connections to the scanner and pinpoint it. Since the test is quick, it will cut down on the Labor charges.

I hope my solution is very helpful to you.

I am not saying to drive the car with the Airride OFF, but go into the trunk before starting your car and turn the Airride off and see if it makes a difference. The Airride may still not be right or the drain on your Battery from the Airride is too great to keep the engine running when the Battery is low.

When you try to start it you should hear the fuelpump kick on. If you do not hear it perhaps the Inertia switch in the Trunk next to the Airride switch was bumped or switched off. Push the Inertia switch button before trying to start your car.

When I turn my aviator on, it makes a clicking sound underneath the engine. buut when it warms up it stops

I will try to help. Noises are hard to diagnose online because a "pop" to one person is a "boom" to another. I think the best way to locate this noise would be to raise the car on a lift and let it set overnight and then start it the next day. The inspection time will be short, until the parts warm up. You can also try to drive the vehicle on ramps, leave it until the next day and then crawl under the vehicle before someone starts it. Again you will have limited time to inspect.

There is one thing to try before lifting the vehicle. In the rear cargo area there is an ON/OFF switch for the Airride. Turn it off, roll down the window and start your car. If the noise is gone, you have a noisy Airride relay. There are scanners for the Airride and you need it diagnosed.

If turning off the Airride had no effect, restore power to it and then start with a cold engine again. Open the hood and have someone start the car while you look at the A/C clutch and listen for your clicking noise. Sometimes when your A/C gets low on Freon the initial start will make the A/C clutch cycle frequently until it catches up. Charge the system to remedy this.

Your exhaust system will make clicking noises sometimes when a gasket called a "donut" (in shop terms ) is worn. The Catalytic converters will also make noise due to heat expansion. The heat shields for the converters can also make noise. Aside from loose welds there is no sure cure for this.

Finally, the engine parts like valve lifters and "Cam phasers" can do this and transmit the sound under the car. This is a problem which a Dealer can help with because there is an extended Warranty for "Cam Phasers". Usually the Phasers do not quieten down under 2000RPM warm or cold. I hope this helps you find your problem.

What do i do when the air suspension does not work?

Check your switch in the trunk on the Drivers side and make sure it is turned to ON. There are also fuses in the fuse panel for this device. Look at the owners manual for a picture and size fuse and if there are other things using that same fuse. You could have blown the fuse controlling several things.

The Air suspension is needed to keep from bending other components and the bags may tear if not inflated. There is a diagnostic plug for the Airride which will quickly point to the trouble. It may be a cheap fix or not. But with the scanner for the Airride you will know before repairs are attempted.

Not all Repair shops have the correct tool. Dealers of course do, but you can call around to Body shops and Alignment places before you go.

Changed the battery two weeks ago. Running great. New pads and rotors changed on Monday...Wed it is deader then a door nail. Had to use key to unlock the door (usually can use the key pad) Any...

You can get a defective Battery. Go to Autozone or Oreillys and get the Battery tested and then bring the Lincoln in for an Alternator scan. When you pull the Battery out of its mount, look for FUSIBLE link wires in that area which could have been pinched when the Battery was changed. With Luck you're fixed.

Now the bad news. If the Air ride was not turned off when the Rotors and Brakes were done, the books say it can harm the Suspension. Since the Airride is Automatic, it can drain the Battery if it runs when it should not. There is a Diagnostic plug for the Airride, but you would have to call to see if they have the extra scanner for this special plug.

While you would want the Brake place to be Responsible for the damage, it may be better to have a 3rd party test your Airride.
