2004 Lincoln Navigator Air Suspension Failure (Part 2) "Replacing The Air Strut Solenoid" 

You should be able to push the airline in and then press the orange plastic ring in, at the same time pull back on the airline and it should come out. Some times debris builds up around the airline so spraying something like WD40 will loosen things up a bit. Good luck!

@@mountainviewsgarage thanks for the quick response. Unfortunately I crimped the line and had to cut it. Not only that but the Selonoid was bad. After replacing the Selonoid both Airbags started to come up but both stopped getting air not sure if I caused a short. Compressor is running. All connections are connected. Airbags are holding air. After much research I am thinking I need to replace the Suspension Control Module which is located behind the glove box on my 99 Mercury Grand Marquis. Once again thanks for the quick response really appreciate the help.

I believe the air suspension control module sends the signals to the solenoids. It should be on the lower left side of the dash above the parking brake.

Ok, thanks for the information I’m going to order the part, I don’t have to do some kind of programming or something similar or it’s just to install it..

Someone commented on another video that they found their air lines actually plugged. It may be worth while disconnecting the air lines at each end and use an air compressor or something to blow air through. No, I don't believe there is any VIN specific programming required for that year.

Thanks. I'm sorry to hear about your experience. I know exactly how you feel when you have a bad experience with a company.

Not a problem, sorry for the delay as I’m not getting notifications. If the car is off, the suspension could deflate as it will try to level out. This can happen if one of the corners are leaking, the entire car will lower to keep it as level as possible. If everything is working properly, the air bags will keep air in them even with the car off. I’ve recently had a few more issues with our air suspension where I did some troubleshooting so I’ll try to get a video together for it. Still waiting on parts to finish but I was able to narrow it down to specific solenoid.

Interesting, I would imagine the ride height control module would be having a hard time trying to manage ride height with only the front air working. Do you know if they reprogrammed the computer when the rear was converted? Typically the air suspension will adjust the front height to match the rear, that is why if you leave it over night with only 1 strut that leaks, all 4 corners will drop. This is the reason why I raise the suspension all the way up, then turn the switch off in the rear compartment, and only the corner that has a leak will usually drop. The bouncy feeling could be caused by an air leak on the strut (which is what we found on our LR3 & LR4) or the air line going to the strut. I've also heard of some aftermarket brand air struts being softer than others. Does your air compressor seem to run more than before? If so, that could be another indication there's an air leak. Good luck!

@@mountainviewsgarage Thank you for the reply. Its not a terrible bounce, sort of a floaty feel after hitting uneven pavement while at highway speeds. I bought the vehicle the way it is, and I didnt realize that the rears had been converted until at least a year after I got it. All of the ride height sensors are still in place. I have no idea if the rears were "programmed out" or whatever. I'm assuming that if the pump was faulty, I'd notice that the front would be droopy but it never is. I think the switch for mine is in the passenger footwell behind a panel, but I've never touched it. This issue (if I can even call it that) is not bad enough that I immediately think something is wrong. Its more of a curiosity.

They are from Arnott. No it doesn’t leak down since I replaced the solenoid. We’ve been down around 5 degrees the last couple of days. Before the air pump and solenoid replacement it did leak down over night.

I found out motorcraft doesn’t make them anymore. So I ordered this from Oreilys online. Arnott Air Suspension K-2230 Airspring Solenoid Just do a google search and find the best price where you’re at. I’ve heard a lot of quality control issues recently with this brand so be aware.

You’ll want to spray some soapy water around where the air line connects to the solenoid. Then lightly push and pull the air line without trying to remove it. Then push the air line into the solenoid, at the same time using something to push and hold the plastic ring into the solenoid pull the air line and it should come out without any real resistance.

After getting the correct solenoid installed and with the new pump, the Lincoln sits more level handles better and the compressor runs a lot less and you can barely hear it inside the car. Thanks for watching!!!
