here we go again ...,now the air ride is way up in the back !.. never owned a Ford that was so persistant with new problems ,/// update on broken axle ,mechanic had no confidence with the axle that broke , and insisted on another entire axle ,,used parts and air bags were a little north of 300 bux, still cost me a 1000 bux ,, but I was able to trade my old axle four new goodyear tires from a recently totaled cop car ../// , now it seems we need a compressor computer or something that stabilizes air ride ,,, also ,, before the the intake manifold fiasco , I noticed the heater /ac fan runs on hi constantly ,, yes it has climate control ,,,and continues to run when switching to off is there a relay or reistat somewhere that has failed ?...any one want to buy this Lincoln for what I have in it ?? LOL it has over 3000 bux of improvements since December .. I am a used car guy , and I know I am getting by cheap compared to new to have a nice clean good lookin ride, BUT, this is the most expensive Ford ever ,. I have bought 3 new truks , the Dodges I still drive , the 85 Ford f 250 was a flimsy weak disappointment, the truck must a been built on Friday before a holiday ,.. crown vics redeemed my love for ford ,over the last 30 yrs , had lots miles of good luck , but lately ,, things are averaging out ,,.
 
When that kind of stuff started happening to my T-Bird, I just traded it off real fast knowing that it was going to become a money pit. Did the same thing with the Grand Marquis. Now I drive Toyotas and avoid all that trouble.
 
People can buy what they want, but many American lives were lost in WW2, so I will not buy a Toyota where all the profit goes to Japan.

I replaced the air system on the Continental I had with a strut kit. About 10 years ago, that kit cost $350. Installed it myself. Came with instructions on how to bypass the compressor system.
 
cant and wont do that with pride , out of respect to my dad who fought them in ww 2,, he knows what they are ,, to each his own
 
Many Toyotas are built in the USA and Toyota stock can be bought by anyone in the World
as can all the major auto company's stock so its anyone's guess these days who actually owns what.If you have a 401(k) you might be invested in Toyota.BTW my relatives fought in
the Civil War against the North so I guess using your thinking I shouldn't buy a Ford built in
Michigan but buy a Toyota built in Tenn.?(LOL)
 
I've never worked on the air ride system, but there must be some type sensor to let the computer know the rear ride height. And since the rear housing was changed, possibly the sensor was not reconnected or damaged? Just a guess...
 
been thinkin along that idea too , mite have another fella look it over ,. just wonder if there is a way to lower the tail end some ? then leave it alone?
 

Those rear air ride systems are as simple as it gets... The bad its 15 years old its aged out :(... Most will take $1000 to get'er going (includes labor), New compressor and rear bags... On the rare occasion maybe a wiring issue were the wiring harness that goes from the rear to the left front rubs threw somewhere just over the right front bumper support...

I have never seen a bad height sensor as long as the indicator is intact they have all been functional...

I would wager the pump is not bleeding off the filter inside the pump is either restricted are moisture has the switching device stuck closed... If you have never put a pump on it I would go straight for the pump, if the pump hammers when running I would go straight for the pump... BTW I have a NEW pump assy I would sell at a good price to get it off the shelf...

You may not be happy with a conversion it kills the ride :(.. Its been awhile since I worked on one so may have to bone up on it just keep in mind its a simple system once I threw out FORDS stupid diagnostic information and the use of a scan tool...

How I figured it out was to disconnect the wiring at the module in the trunk then make up my own harness that ran over the roof to the compressor from there I could see what the height sensor actually did and how the pump only needed that signal to lower/raise/ are bleed off...

I have not priced the parts lately I would say if you can do the labor its cheaper to get it back to its original state a original ride that can not be beat...
 
The air compressor is what vents the air springs, the solenoids on the springs only control the air going in. There is one right height sensor and its mounted on the rear axle housing, I would look at that sensor first. If the compressor is noisy, and/or rear bags cracked/leaking I would consider converting the rear air springs to regular coil springs. If you still had the donor cop car or access to it, then you can use those springs or any other c-vic/g-marq or buy a kit.

The blower motor problem is most likely the blower motor speed controller, yes they are problematic too. This part is on the HVAC evaporator housing under the hood. Look just behind and above the passenger rear blower motor, right under where the heater hoses go into the firewall. Its a tight fit to get in/out but not that bad to replace.
 
When they replaced the rear axle they should have replaced the air ride system with the springs from the wrecked patrol car. With the work being done the springs would have been $50.00 and the installation near fee with the work already being done.
 
Can't you just get a kit to bypass all that expensive junk ? I know there is one for Cadillac's. Wish I could remember the name of the company.

You've never owned an early Expedition then, have you? My air ride rarely works right. When/if I get my '00 fixed it's gone, assuming I can at least get the cost of some of my repairs out of it. Might be worth more as a tax deduction donating it to a nearby charity!
 
What year is it? If you bought an old Lincoln with anything over 80K miles you were asking for this issue. I love Lincolns and drove them exclusively for about 16 years. I had a 1992 I liked a lot and kept for a long time. Air bags were $1000 a wheel back then. You lose the Lincoln ride if you don't have them. Great cars back in the day, but they ARE a luxury auto and they ARE expensive to fix correctly. Sort of comes with the territory.

At least on my Expedition there are three, IIRC, two in front and one in the back. Have had them all replaced at one time or another. The spring kit is tempting if I keep the stupid thing and I have more issues with it. There are YouTube vids that show how to install them, looks easy enough.
 
I installed a spring/strut kit on my son's 1990 Town Car- the old bags leaked, caused the compressor to run nearly constantly to keep up- something it was not designed to do. It failed, then they slowly lowered. Kit was around $300, raised the ride a little, but still was plenty smooth for a kid's car.
 
Yo Bob, As you know Im the proud owner of a Chevy car,,,,,,Chevy Truck,,,,,,Chevy Motorhome. Im not a fan of a dern old Ford though lol but I will be nice in case I need pulled out of a ditch this winter !!!!!!!!!!!!!! If I ask you just remember ID DO IT FOR YOU

First and foremost, you have to be willing to pay Lincoln prices if you want to drive a Lincoln. Now, having said that, I suggest that the air ride system is not terribly complicated. Any half decent mechanic should be able to service it. The rear system is about as simple as it gets. A control module, a sensor for ride height, and a compressor to supply air to the bags.
There is no such thing as setting it to one height and disconnecting it. There is a control system because there is the need for it. After all, Ford did not spend the money on it because it was not needed for the system to work.
A few thoughts I had were:
Did the mechanic replacing the axle remember to turn the system off while working on it?
Did the sensor possibly get damaged "by mistake" because somebody forgot to unhook it before lowering the old axle out?
Did the mechanic remember to re-connect the sensor after completing the repair?

It is really a simple system. Most replacement components can be found at salvage yards for low prices. Compressors have been used since the '80s on air ride systems. Lincoln Mark VIIs and Continentals had air ride as far back as 1984 - possibly back to 1981.
 

Yes, it is a fairly simple system and I have repaired a few of them.

To me though, the easiest and cheapest solution is to get the regular type coil springs and any other required pieces from a scrapped Crown Vic and convert to a tried and true trouble free setup.
 
Air ride's a good idea but a money pit after it's 5 years old. GM tried it in '58. I had a '58 Buick with the air ride option and it was a good system, BUT they neglected to install a dryer in the system after the compressor. Everything rusted out from the inside and you had to start replacing all of the components one by one. That Roadmaster sure had a smooth ride, though.
 
My dad worked at a GM dealer in the 50s when that came out. He had some interesting stories, said cars came in stuck in every position. They released a delete kit for the cars so the dealers could take it off.
 
My 97 and the 2000 I put the spring kit in. You can find them on the internet. It's Strut kit I think. There from the Carolinas I think. any way it takes about 45 minuets to switch from air bags to springs and you can't tell the difference.
 
Turn off the air ride switch in the trunk. Drink a cup of coffee and turn it back on,start the car and wait two or three min. to see if it settles down,if not, check the linkage on the ride height switch for binding or maybe bent during the axle switching.
 
I did the Monroe kit on my 99 Navigator. Can actually drive the thing now. Best thing I ever did to that truck. I've never had a vehicle be such a POS that raised my blood pressure like that Navigator. It should have had a brick put on the accelerator and driven right off a pier when it was brand new. I know one thing it did very well though. It totally convinced me to NEVER buy another Ford product for the rest of my life and that's all we've ever had here. NO MORE.
