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.

Driver side of 2003 mercedes e500 wont rise

The easiest fix is to hook up a scanner on the suspension test plug. This will give you a test to each sensor. Some models may even record a history of performance.

Underneath the car, someone can use soapy water and spray the air lines and suspension bags to test for leaks. There are venting solenoids on each wheel to level the car and a Master solenoid called a "dump" valve to release all of the air

The system is tied into the doorjam and trunklid switches which must be closed to allow the system to work. Escaping air should be easy enough to find.

I have 97 mark viii n I c that everytime I get out the front end is always on the ground but it do rise up when I start it

Your mark viii has a air ride system. and as you drive, it has a pump under the hood. well over night it leaks down. then when you crank the engine .this pump will come on and air up the air ride system.kind of like a tire.But if just the front goes down ,Then you have a leak at the 2 front bags or lines, or connections. to find the leak try some soap in a spray bottle. after the bags are fully aired up and the engine off.some Lincolns leak worse the way they sit. it could leaking in a few places,that is what the soap is can buy every part for that system from, Air Suspensions out of Orlando FLA diagrams

I changed the compressor for the suspension , seems to be working but not lifting the car. Do i have to add air

If it is not lifting and the compressor is running, you have a leak in a hose, or a blown air spring, possibly an open solenoid-but try first to jack it up about 4 inches (shut off the compressor switch located in the trunk on the driver side fender)-you might have to drive the car up in some 2x4's to get extra height so you can get a jack under the car so it can be lifted-get it up so that it is off the tires, turn the compressor switch on again, and turn the key on again (or start the car)-see if it will raise now. If not, you need to look (or listen) for a blown bag or leaking hose. Do not run the compressor too much or you will replace it again-let it cool off in between attempts to locate the leak (soapy water in a spray bottle is your friend). the compressor is designed to 'time out' after about 90 seconds, so if it shuts off, let it rest, look around, and try again in 10 minutes after you have looked at the bags and lines (especially make sure they are pushed into the various locations. And, there are always spring conversions-once you do it, you never have to worry about the bags again. Air ride is nice but after 8 years, bags need replacing, and a system that is leaking ends up taking out other things like compressors, the hard to find relays, the dryer, solenoids at the bags, air ride modules, hoses...a decent spring conversion costs about $450, you can find used ones on ebay for as little as $200, and are not too hard to install with good tools and maybe a good helper.
