Hi, sounds like your air solenoid switch located on top of the air bag where the air line connects to on top of the bag. It is almost impossible to see this switch without removing the air bag because of it's location. If there is air in the bag now, the only way to release enough air to get the solenoid out is to find a Ford STARR reader. This tool is the easiest way. No tool, with the rear frame raised (not axle) and air suspension switch "off", take a long thin flat head screwdriver, with car raised and wheel off ground, look dead center on top of tire on the other side of the frame rail that curves over the axle, you will see a circular (probably rusted) half circle far in the back, take the screwdriver and pry under this until the half ring is off. Next, go under axle, look up following the top of the airbag. Take your hand and "twist" the round solenoid connecting to the top of the air bag. When you twist it and pull, the air will release all at once. Disconnect the wire at the terminal, and disconnect the air line by pushing on the small orange colored ring down while pulling the air line at the same time. Install air line to new solenoid by pushing the air line into the orange ring then lightly pull back and it will lock. Connect the terminal wire, push and twist into air bag and place new half ring clip onto solenoid, it will snap into place when installed correctly. Don't forget the clip, the solenoid could slip out from vibrations if not clipped securely. Lower car to where the tires are touching the ground and a few inches lower, but don't release the jack yet. Turn air suspension switch "on" and start car. Let the air bag fill up until the pump stops. Repeat by turning car off, then on again after 5 minutes in between. Lower car a few more inches and repeat until jack can be removed and air bag is filled.

1986 lincoln matk vii left front air spring will not lift up to level position

Have you checked all air lines, are they all tight & have the orange O-rings on them, this includes the one that goes to the top of the solenoid on the air bag that you're having the problem with, Then you might want to inspect the air bags itself, for leaks and cracks. Don't forget to turnoff the air ride system, the button is in the trunk before you jack up the car. Finally, there is a way to check the system without any special tools, just a jump wire. Let me know if you like to know how to do so.

My 98 cadillac rear air suspension will not left the car ?

You may have a bigger problem than you are looking for. Often times with these air systems there are air lines and air bags that dry rot and crack there for causing leaks everywhere. This can burn out your compressor. These problems can be very costly. I replaced the compressor twice before I was told that my lines on the car were no good anymore and the air bags had leaks too. Instead of paying over $1000 to fix the air ride, I went with a non air conversion system from Strutmasters. It was cheaper than fixing the air problem and it it rides great! A lot less headaches with it that is for sure.

Just had car dealership repair 1997 lincoln town air ride

Those Lincolns are notorious for that,I'd just get a set of coil springs out of a Crown Victoria cop car(junk yard)and swap them out.Done it many times,you can do it in about an hour,and they'll never leak down again.By the way,there's some O-rings in that system.Make some soapy water and spray every connection,just maybe you'll get lucky.

Air ride suspension 1997 ford expedition

If the compressor is working and actually pumping out air, might need to check your lines dont have a leak by disconnecting them from the bags. If pressured air is making it to the end of the line, then bags may need to be inspected and one or both replaced. However it is more likely that the lines are leaking or the compressor pump needs a service. Just a new set of rings in the unit. Good luck, hope it helps.

I have a 97 MKVIII with a mal-functioning  air suspension system. Parked on level ground the front end suspension depresses overnite. and upon starting it comes back up in the morning. It sometimes will...

leaks can be difficult to find in these systems. They could be in the air springs themselves, the air lines etc... not to mention you could have a ride height sensor that is malfunctioning or the control module. A lot of people are converting these old cars from the air ride suspension system to a standard passive coil spring conversion. A high quality, powder coated, American steel coil spring is DESIGNED to last the LIFETIME of the vehicle. offers conversion kits with a lifetime warranty so youwon't have to worry about your suspension again. Give them a shot.. it definately beats the dealer price of around $1200 to fix your air ride.
