What is a solenoid. I have a 2000 expedition Eddie Bauer 2 wheel drive and the rear air suspension lever is not working. What part can I get to fix it.
The solenoid sits at the top of the air spring and is connected to the air hose that inflates the air spring.
you untwist it to remove it from the air spring. it unscrews in 2 steps normally as a safety so it doesn't come off under high pressure..

Your air suspension is leaking, could be a air bag or line or a fitting or a dump valve. Get a spray bottle full of soapy water and start spraying down the air ride components and watch for bubbles.
This is normal operation for this vehicle, the air in the air ride suspension system is designed to do this. After the vehicle sits, the air ride suspension will slowly release the pressure in the system until the vehicle is started again, and the air ride will level itself out again.
If you recently had your vehicle serviced, it is a safety practice to turn off the suspension. The switch should be located behind a small access panel in the cargo area of your Expedition. The switch is usually on the Drivers side and paired up with the fuel pump Inertia switch. If you do not see it on the rear quarterpanel interior panel, try the passengers side. Do not confuse the solid plastic access panel with the Stero speaker cover.
A second type of control appeared in 2007 in Navigators. Yours is a sister vehicle. The off/on controls can be in the message center and you toggle the controls with the dash buttons.
The air suspension does have a fuse, but usually this does not break unless there is a problem. You can take it to a repair facility having a Air Suspension scanner, which can diagnose a hidden problem immediately.
The compressor should only run until the rear suspension reaches the desired height. If it continues to run after the suspension has raised to ride height then you may have a leaking air bag/solenoid or line. If you dont have any leaks it is possible the EVO(air suspension module} or relay is at fault.
i had this problem on a navigator it torns out that they have achip by the fron fender well that burned and all I had tto do was replce it it was not cheap 125.00 but solve my problem
I had a 1999 Expedition. When you put the 4x4 on it raises the vehicle an extra inch or 2.
It may help to turn the 4x4 off. Two wheel drive is a lower air setting.
Your original pump may still be good. The problem can be in the front. The compressor is not filling the front suspension to the cutoff point. It will lift the rear after the front end is at running height. Since you lost the front end first, the remaining air bled out there and then the rear came down. Once you shut down the car the suspension was done, all the air was let go.
There are adjustment solenoids on the body but you need someone qualified to repair this.
