Does the pump run a lot? My pump on my '91 ran all the time so I checked my rear struts and they were bad. Had them changed and the pump doesnt run so much now.

Mine did exactly same thing. I simply disconnected it. It does not affect the ride at all.

My 95 town car still won't rise after changing the compressor and rear air bags. Check compressor relay and fuses and they are good. compressor starts when pins 30 & 87 are jumped. Now my car won'

There is a master dump Solenoid that should be below and inside the Drivers' front fender or valance. This Solenoid lets all the air out of the system. It can rust OPEN and freeze the system.

The ability to pump up the air and activate the compressor ONLY occurs when the car senses that all the openings of the car are closed. This means the trunk and the doors. The idea being that the car is allowed to squat low so loading the trunk is easier and the passengers can enter the car easier.

The Air-ride system has a test port for the Module and a Scanner can be connected to analyze the system. It takes a Scanner capable of reading that special system.

The battery can drain if a door switch in the domelight circuit is touching a metal part. The doorjam switches have 3 wires instead of 2 if the vehicle has Air-ride.

You can do a Web search for locations of the parts you want. Youtube sometimes has videos of a specific repair.

This is something a good scanner can save you money with, because it quickly finds the problem and you are not buying parts you don't need. Might be worth it to go to a Dealer or electric shop having the right tools for this.

My new car battery keeps dying over night

It takes quite a drain to discharge a battery in 8 to 10 hours. Have your charging system checked free at Autozone, Advance, or Oreilys parts stores.

A bad diode in an Alternator will allow a significant discharge.

Other items are stuck switches for rear Window defrosters, window switches, and so forth. Air-ride systems with leaks can drain a battery trying to maintain a pumped up vehicle.

Stuck Relays. When a car is started, the Relays in the Powerbox activate and supply power and grounding for different controls. When the Ignition key is turned off, the Relays are suppose to release and break the connections. If a Relay has melted its' contacts together it can not disconnect the circuit and the devices stay on draining the battery.

The Dealer has a wiring machine which can be plugged in between connectors and diagnose which wires are properly connected. Hopefully you will not need this service. There are slower ways to check, but if you are paying someone to do this slower can mean more expensive.

My battery is dead every morning, I noticed the compressor from the air ride suspension goes on about every 5 to 10 minutes. Could this be draining my battery, can I turn it off at night?

The air ride is getting ready to go out. You have a leak somewhere in the bags or lines and it's causing the compressor kick on more than usual. The more it kick on, it will eventually burn the pump up.You can turn it off but it will still lose air that's in the bags. I just had all of mine pulled out and replaced with shocks and springs, and it rides nice. But also, depending on where you're from, the weather has a lot to do with a battery losing power. Cells could be getting dry or worn and not holding a well charge over night. Matter of fact my vehicle does it now, need to go get me a battery. GooD Luck

Took truck to advanced auto they put diagnostic on truck once they were done tried to leave gauges, lights, and radio went crazy...truck died and they jumped truck, once jumped same thing happened backed...

Hello, From the symptoms you gave, I would say the Air-ride system is part of the problem. You also have a secondary problem caused by the constant drain on your battery by the Air-ride compressor. This is activating the Battery monitor system which is trying to preserve the charge in the Battery.

There are several things you can do. For the Air-ride, you can use soapy water in an old spray bottle and go under the vehicle and mist the suspension bags and air line connections. If you see bubbles where you sprayed or hear escaping air, replace the part that is leaking. Or have the Expedition taken to a place where a Scanner can be used on the Air-ride system. Sometimes Autozone, Advance, or Oreilys will have a better Scanner that can do the Air-ride module. If not, you need a Dealer or Independent shop having such a tool.

The Air-ride system depends on all doors and the rear Cargo lid being closed before the Expedition will pump up the rear bags. If the rear lid is not closed or if any door jam switch is broken, the Vent-valve(Dump Valve) will not close and the air will escape. If you can hear escaping air after following the air lines to the Drivers forward front fender, then the Vent valve is probably stuck open.

The other problems you were experiencing could be due to a bad Alternator and/or the Battery being too low. The Battery minder will disconnect the charging system AFTER a jumper start has been done. I have clients who lost the charging circuit at 70MPH, just because the Battery was too low. Once 3 to 5 minutes has passed, the Battery monitor can disengage the charging circuit without warning.

Charge the Battery above the listed 12 Volts, a good charge is 13.2 to 13.6 Volts. When this is done, the charging system will work again, unless the Air-ride compressor is drawing too much juice.

The Battery needs to be disconnected from the vehicle cables but can be charged on the vehicle.

There is a toggle switch under a plastic cover in the rear cargo area. You can shut off the Air-ride but it is not recommended to drive it shut off. All of the news is not bad, one single sensor or switch can fix the entire system. Getting the Air compressor to stop running has a good possibilty of fixing the power drain for good.

This is why I mentioned Scanning the Air-ride module. You have a big time/labor savings when the Scanner identifies which wheel is causing the problem or which doorjam switch is bad. I hope my solution is helpful to you. Be careful when the Air-ride system is pressurized as it is a Hazard to jacking the vehicle and wear safety goggles.

NOTE: This procedure may be easier if the radiator and shroud is removed. If the radiator is not removed, place cardboard in front so not to damage the radiator core
  1. Open the hood and disconnect the battery. Remove the lower engine cover.
  2. Drain the cooling system. CAUTION
    When draining the coolant, keep in mind that cats and dogs are attracted by ethylene glycol antifreeze, and are quite likely to drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantity. Always drain the coolant into a sealable container. Coolant should be reused unless it is contaminated or several years old.
  3. On cars without air conditioning, remove the fan.
  4. On cars with air conditioning, remove the air pump and generator mounting bolts, then remove the fan and air pump drive belt (pivot the generator and air pump in toward the engine). Remove the fan and pulley with set plate. Remove the hoses to the pump.
  5. Remove the 6 bolts attaching the water pump and remove the water pump assembly. Clean all gasket surfaces carefully. To install:
  6. Install the 6 bolts attaching the water pump with a new gasket.
  7. On cars with air conditioning, install the air pump and generator mounting bolts, then install the fan and air pump drive belt (pivot the generator and air pump in toward the engine). Install the fan and pulley with set plate. Install the hoses to the pump.
  8. On cars without air conditioning, install the fan.
  9. Refill the cooling system.
  10. Connect the battery, start the engine and check for leaks.

Air pump stays on when key is off

The air pump is not in the trunk, and it is not for the air ride. It is used to reduce tailpipe emissions. it is actived by a vacuum valve/solenoid.It could be a bad vacuum valve or check valve. Save yourself a few bucks and go to an auto parts store and get a haynes repair manual to locate these parts, and replace them yourself.
