Air ride suspention front won't work. Compressor works for the back but then shuts off and doesn't pump up the front

1. NOTE: Air compressor and compressor air drier assembly is located ahead of the front RH wheel. It may be convenient to service the solid state compressor relay and the four air line connections by disassembling and carefully bending back the forward section of the RH front fender apron (16054).
3. Raise vehicle on hoist. Refer to Section 00-02 . Suspension must be in full rebound.
1. Remove wheel and tire assembly.
1. Remove RH front fender splash shield (16103).

First you need to have Suspention Control Module scanned to retvieve troube codes.
The common code is C0660 exhaust solenoid fault.
The exhaust soleniod in the rear suspention air compressor and is a common problem for having an open circuit internally.
The solenoid is not serviced seperate, will need an air compressor assembly if this is found to be the problem.

look at the ride level sensors on the rear syspention the arms fall off the sensor and the system doesn't know its low

Putting on a car lift without turning off air ride won't affect the system, to reset the air ride system requires a code scanner and plug into port, try calling some auto stores to see if they can do this or have a cheap unit to reset, or take back to garage and fight with them to reset, or go to different garage.

It may be helpful for you to get some idea of the mechanism involved in operating the shock absorbers in your vehicle. Refer this information. It may then be a matter of finding the parts involved if replacement is required

there is a ride hieght sensor on rear lower control arms creck for damage and connection.over load rear suspention,4/5 people on back bumper with key on see if pumps up.also check fuses.try jumping compress to test compressor.worst case replace struts and use coil springs,eliminating air ride issues.

Use a test light to the air suspension pump to see if it is getting current. I assume that the rear end is sagging a bit as far as ride height, due to the pump not working. Also, may try to remove and replace pump, assuming that's the problem, and then when the rear air shocks pump up, make sure there are no leaks after shutting down the vehicle.

Also, make sure that the shut off switch for the suspension isn't flipped to 'off.'

It needs to be working to blow air into your back suspention.The pump is under the floor by your door.Its in a drop down box.Check the pump your self or have some one check it for you before you buy a new one.Has i now the swiches infront of the pump fail and so does the micro swiches on the rear suspention arms The Micr swiches activate the pump and are a real problem with the land rover.I would change them firstly.The compressor pump is around $600 new.So check the above before replacing.Good luck phil.

it sounds like your air compressor for the air ride has gone out but check the lines first and an F150 and a lincoln navigator has the same compressor check one out at a salvage yard for alot less then new

The air pump is located in front of the radiator reservoir on the passenger's side - with the power steering reservoir between the two.

The air ride is turned on in the truck. The panel in located on the opposite side from the gas tank input (inside the trunk) behind a door. It should be marked on the door.

Make sure the air ride is enabled. turn the ignition key on, You don't need to start the vehicle. After about 5 seconds the air compressor should engage. You don't always hear it when it's running well. Since the engine is off, you should be able to hear any leaks in the air system.

Possible causes:
Hole/crack is air spring
Hole or broken air line or coupling
Failed air compressor

The rear suspension should use the same air system. If the pump is 'out' then the rear will also fail to adjust, But since it is on a separate air-line and valve system, it will continue to operate when the front has air leaks. And vise versa.

One pump
Two suspension systems - Front/Rear
Four air springs - One for each wheel

Another possible problem:
Your front wheels have a censor to indicate the height of the vehicle from the ground (basically). If this come unclipped, your system will think It's too high and will not add air to bring it to normal height. This usually happens on ONE side causing the vehicle to 'lean' or seem to. One side will have the wheel up in the wheel well, and the other will be a bit more gap between the wheel and the wheel well, but may seem to be 'low' too. On the side which is lowest, turn the wheel that direction and look on the front of the suspension arm for the sensor. it should be attached top and bottom.

If the clips have failed, there are no replacements available from the dealer, and replacement of the sensor is required.
