Hey all! I just purchased my first TC (2010) a few weeks ago and it does not have air ride suspension. I can’t find evidence that it ever had it in fact. It has standard components and no evidence of a compressor or lines or even the fuse socket ever being used. Was air ride NOT standard on the TC during this generation or is it likely someone changed it over?
It is the Signature Limited. Emphasis on “Limited” I guess. Yes even the cutout for the switch has no witness marks of any kind. I’m pretty certain now that it never came equipped with air ride. It’s still a great riding car but I have always wanted air ride.At first read, it looks like a very thorough removal of the air-ride system. What is the trim level of your Town Car? If the air ride became "optional," it would be most likely to not be present on the lowest trim level.

2003 TC that belonged to my Mom who passed and this car was her love so now it’s my love.
Ok then, I haven’t gone through all of the troubleshooting in this thread yet but generally speaking, shiite-can the air suspension or restore the air suspension?
Sorry about being vague. I read the whole 8 pages of the post and have the a$$ end up in the air so I can start spraying soapy bubbles.
What happened was that the bags were progressively getting worse in holding an air charge (making the comp come on more frequently). Then one day she looked like a low rider. It now stays looking that way all the time but it feels like the bags get a little lift after driving - if feels like it is up off of the bump stops while driving. When I first started noticing something was changing, I measured the top-most tangent point on the underside of the wheel Well lip and it is way lower now whenever I measure it.
I’m going to give it a thorough visual inspection and then try to get some air into the bags to start the soapy bubble inspections.
Because it is my Mom, I intend to restore the vehicle to its former glory and I will keep it with the air suspension system. I‘ve looked at strutmasters and parts geek and the parts can be had relatively inexpensively.
Well, the investigation didn’t take long!
The next analysis will be to determine how much to replace? Do I go for everything down to the nitnoid level or maybe just replace the actual air bags and whatever is tucked up inside of a steel channel at the top of the bags. I can barely see up in there but when I felt around up there I could feel the air tube plumbing. I’m hoping that I will be able to replace the bags and air plumbing and the solenoid valves - the hard to reach stuff - and go back later for the comp and tubing?
I’m thinking that replacing the bags are the most important by virtue of the unintended adverse impact on other things like the stand alone shocks that are independent of the bags. I think those are what’s keeping the suspension somewhat off of the bump stops, statically.
I checked the heights and they are even but they are at 25 1/4“ no matter how I tried to tri€kfu¢\< the system. The original measurements on Jan 18th of 2020 are about 4” higher. I must have suspected something then because something made me want to start measuring.
Copy all on inspecting everything in the system - I did a quick look while I was under there. I figured I’d go ahead and replace most everything just like you said, I don’t want to do this again.Hi, spurlockda.
The stuff "tucked up inside a steel channel" is probably the wiring and air lines. Be sure to inspect everything while you have it apart to make sure, but most of it is probably fine.
The only reason I would hesitate on just replacing the solenoids along with the air springs is that they are $125.75 each, and they might not have anything wrong with them. After removing the air springs though, you might just decide that $251.50 is not too high a price to pay to not have to cozy up with the rear axle again any time soon.
I would use new mounting hardware for the springs.
The ride height sensor is also back there. You will want to check it to make sure that it wasn't damaged or knocked out of adjustment with your springs failing completely. You might also think about replacing the rear shocks, especially if you had any doubts about them before the air springs gave out.
The compressor is mounted under the air cleaner box under the hood. While having the air springs go out hasn't done it any favors, it probably hasn't been hurt yet.
While replacing the air springs is much easier to do on a lift, it can be done on good jack stands.
