    the tires are sitting on the truck .I put a new air compression motor in it and it still did not raise up

  • amyjo109 Dec 18, 2008

    I am curious if yours does this primarily when it is cold out? Also My compressor made more noise than i thought was normal... Mine would work on warmer days then once it got below freexing outside it wouldn't even come on...

    I have the same problem: check air suspention. Is there a switch to turn the air supention on and off like on the 2000 models?

    We have the same problem on our 2004 Lincoln Navigator. Wondering if we have to take it to the dealership or if we could take it to some where like Midas?

    Well I have come to the conclusion that it is not the weather.. we seem to have a short somewhere in the wiring.. If we jiggle the wires that go to the compressor (behind the passenger headlight) Then sometimes we can get the pump to kick on ??? We have had it at the garage several times. They are thinking now that it is a ground wire ? Hopefully we will find out soon

    If the fuses where the issue the warning light would not illuminate, u need to have the system tested, there will be a trouble code stored for the problem, only the dealer has the test gear to do this.

Need help with a 2001 Expedition air suspension problems


I will try to help you. There are just a few things that can be tried for free and sometimes a better Scanner can be hooked up to diagnose the suspension system. The Scanners vary by store among Autozone, Advance, and Oreilys autoparts.

The Relays in the Powerbox could be bad. Register your vehicle on Autozone.com and get free Fusebox layouts and wiring diagrams, which are color coded.

The rear cargo lid and all 4 doorjam switches must be closed in order for the airpump to work. There should be a Master dump(vent) solenoid inside the Drivers front fender ahead of the front tire. When this solenoid corrodes, it can stick in an open position and lock out the airpump.

Inversely, if stuck in the opposite position, it can keep the car raised up.

For the airlines and suspension bags a mix of soapy water in a spray bottle will detect an air leak when sprayed on the lines and suspension bags. This will produce bubbles. But the suspension does need to have air in it for this test to work.

When you do have pressure, remember that these are high pressure lines if you go to disconnect them and protect your eyes.

There are a few parts sites like Carparts or Car-parts.com which deliver Salvaged parts directly to your door via UPS or Fed-Ex. Price comparisions give you a choice of who to buy from and the site has full contact info.

You can get a clue from how the vehicle sits. If back is down or if one side is down, a partial inflation means the pump should still be good.

I hope my solution is helpful.

Purchased focus sport 2006 model no service manual. Mileage 43,000 kms. Need to know service intervals either time/mileage perhaps a copy of the service schedule will suffice.


These maintenance intervals come from the maintenance interval calculator
at www.autozone.com, using a starting point of 25,800 miles (43000 km), and
assuming 1000 miles (1666 km) driven per month, and "severe driving conditions," which
are actually normal usage characteristics, such as frequent short trips, urban driving, waiting in traffic, driving in hot weather, trips under 16 km in cold weather, etc.

Have a 2000 eddie bauer and the entire rear end is sitting low with the front remaining the same, this seems to be happening often, whats the solution


do you hear the pump running from under the back of the car? check fuses? is the suspension light on in the dash? this system is diagnosable with the right tester.have someone get the fault code from the suspension module. could be as easy as a sensor. was the car towed recently? flat beds ofter knock off the sensors when car gets tied down. my air suspension went out on me. And the dealers price was too expensive and i went to Strutmasters.com and bought a conversion kit that eliminated the air and has a lifetime warranty so now i don't have to worry about it ever again. Prior to jacking or lifting a vehicle with air suspension, you must turn off the suspension switch. find the reset switch auto parts store will tell you where its at

I have just had 2 new tires installed on my 1997 ford expedition. As i was driving home i noticed that the "Check Susp" light is on. This light has never been on before this. Could it have been something...


They probably picked the vehicle up on a lift and let the suspension hang.... Air ride suspension has a device to monitor vehicle height. They should have disabled it first... Now you have a serious problem.. Take it back to them and let them fix it.$$$$

Warning suspension workshop message appears in center display ride heigth cannot be reached. . passenger front suspension does'nt lift.


Hi!

Your vehicle is equiped with a small compressor that pumps air into either a bag or shock absorber, each one has a leveling mechanism that sends the signal to pump more air to that particular side. This keeps your vehicle leveled at all times, like when you have passangers in the back sit, passenger sit, or luggage.

The message you are getting means that either the air is not getting to the front passenger suspension to level it up, which could be due to an air leak, or the bag or the part of the suspension that lifts that part of the vehicle is defective.

You can get a diagnostic at any reputable suspension shop at no charge to find out the exact cause.

Good Luck!! Don't forget to rate this post!!

Abs light come on and 4wd light flashes


check your front wheel bearings by jacking up the front end of your vehicle and trying to wiggle the tire at the top and bottom of the tire. If the tire seems to be jiggling a little bit at the hub; not the suspension or steering, your wheel bearing needs to be replaced. If it gets really bad you can actually see the wheel inverted or the top of the tire leaning towards the inside from the front of the vehicle.

when your wheel bearings go the sensor in the bearing goes off and the abs light comes on.

Good Luck

The check suspension light came on. I have noticed that the vehicle is sitting uneven after the airbags deflate once the vehicle is turned off. Lately the vehicle also seems to not have an airbag inflating...


Definitely sounds like there is a leak in your air suspension somewhere. I'd have a local shop check it out. There is a switch for the air suspension either underneath the glovebox right hand side of firewall. or in the back of the vehicle behind the left panel. it is labeled suspension
