1996 camaro keeps hitting the ground


most likely you have bad shocks. With the car sitting level, push down on the back bumper hard and then let go. If the car comes back up and then down again, the shocks are bad. You may also have bad springs but most likely you have at least one shock that is flat.

Can't find the relay for the electronic level control(elc) for a 1999 cadillac eldorado


1. Locate the automatic level control height sensor under the rear of the vehicle on the rear suspension support. If the back of the car is too low and will not pump up, ground pin B Yellow wire and see if the compressor will come on and the car will raise.

2. If the car does raise when pin B is grounded, check the powers and grounds to the height sensor.
3. If the powers and grounds are OK and the pump does come on and the car raises when pin B is grounded, the height sensor will need to be replaced.

4. If the car is too high and will not come down, ground pin E White wire at the height sensor to see if the car will lower.

5. If the car lowers when the White wire in pin E is grounded, check the powers and grounds to the height sensor.

6. If powers and grounds are OK and the car does lower when pin E is grounded, the height sensor will need to be replaced. Tech Tips: There are two different automatic level control systems for this car; one is without RPO F45 and one is with RPO F45. The system without F45 has an automatic level control height sensor and with F45 the automatic level control compressor is controlled by the continuously variable road sensing suspension module. Tests/Procedures: 1. Using a head lamp as a load, test the ELC height sensor power/grounds.

2. The power feeds are: Orange wire, pin C and a Brown wire, pin D.

3. The ground is pin A, Black wire.

4. Ground the White wire at the height sensor, check that the vent solenoid in the ELC compressor clicks and vents the air from the system. Author: Bill Siegmann

Rear air suspension


The air system does not lower when you get out, it levels the car and stays level, but is you put weight in trunk and people sitting in the back seat and the car lifts to level out with the weight and then you remove all the weight and rear end is to high up then there is a problem.
These bags do not lift that high, if you hear the solenoids make sure it is not lower , measure.Also, the release of the air is very slow, make sure it is not lower, if you hear the solenoids open the car may be lowering very slow. check the height.If you are sure its not lowering then you may be correct in saying the level sensor may be bad. the only other part would be the solenoids but i would start with the level sensor as the air is going into the bags.
I quick test to check solenoids at bags is to start car and go rear the rear and locate the sensor, remove the arm from the control arm and bring it down so computer thinks car is to high and see if air is released. caution don"t stay under the car as it will lower down slowly. if it starts to lower then turn key off and reconnect lever and replace sensor.there is a company we use that is real good at this air bag system and prices are good with quality parts.http://www.arnottindustries.com/part_LINCOLN_Air_Suspension_Parts_yid2.html

Seems like the rear of the car sitting lower than the front like its doing a wheelie.


You probably have a bad leveling system in the car which is controled by air bags in the rear suspension.

My 2001 Ford Expedition looses air in the rear air bags after i cut it off. I don't hear any air leaks or anything! What can be the problem?


the air bags release air after it sits. The rear raises back up after starting engine, if you add weight, it raises up even more to compensate for level suspension. It should be fine unless it's sitting almost on thr ground, but it does release air and sit lower.

Rear of the car levels off after being driven, but lowers again.


Yeah but the dealer should have done it. The sensor is controled by a rod conected to the axle. If this rod isnt wrong the car will not level to correct point.
while driving is the car level?
There may be a minor leak in the air system somewhere.
Since you took it to the dealer and they charged you I say complain about it untill they fix it right.

2001 Lincoln Navigator Air Suspension


the auto leveling is standard on the navigator.
first you have to understan that the auto leveling system is on front and rear of these trucks.
one way to tell is do you hear the pump running and do you have air in the front bags. and if you do you need a rear level sensor.
