I replaced the Air shocks with regular springs from a conversion kit I purchased on EBAY. The instructions to disable the "Check Air Suspenson" light were included in the kit. I followed these instructions without success. I disconnected pin #11 from the wire harness under the dash, behind the glove box. I then telephones the company and was told to cut the black wire to the air compressor under the hood - below the ait filter cannister. HELP!!! how do I TURN OFF THIS LIGHT????? I own a 1997 Lincoln Town Car signature.

Have you driven it yet? How do you like the ride compared to the Air Springs?

No help. I have a 97 model sig. I guess it is different. There is no green wire behind the glove box. Pin #11 is gray. I did not cut it but removed the pin from the harness and it did nothing. I have tried taking out the fuse under th hood and the relay - no effect. I had someone from suncore tell me to cut the ground wire to the compressor under the hood - no effect either I just had to figure out how to splice a short wire back together (ughh). Any ideas?

Here's the instructions I got from Arnott Industries:

Disarming the Air Suspension System

1990-1994 Town Car
The module is located in the trunk, behind the air suspension switch.
Pull back the trunk carpet and remove the 2 nuts that mount the air suspension module. Unplug the air suspension module and bolt it back in place.

1995-1997 Town Car
The module is located behind the glove box.
Flip the glove box down and locate the air suspension module mounted on the heater core directly in front of you. Unplug the module and close glove box.

two ways work great
1. go in behind the dash and remove the BULB.
2. cut a 1/2 inch square piece of black plastic electritions tape and paste it over the air susp lite.
# two worked for me till i got new bags.

There Should Be A Diag Connector In The Trunk Peel Back Carpet And If You Ground One Of The Wires Not Sure Which One It Will Turn Off Trial And Error.the Connector Is Kinda Triangled Shaped.monroe Gives You A Connector With There Kits I've Installed Before It Will Work Just Have To Find The Right Wire And Ground It Somewhere In The Trunk

I FIGURED IT OUT AFTER A WEEK OF :banghead:

RIGHT BEHIND THE GLOVE BOX (TAKE THE GLOVE BOX OUT) IS THE CONTROL MODULE. THERE ARE A GRAY AND A BLACK CONNECTOR, DISCONNECT THE BLACK. IF YOU ARE AS ANAL AS I AM AND DON'T WANT TO CUT ANY WIRES, REMOVE THE RED CENTER DIVIDER FROM INSIDE THE CONNECTOR, IT JUST SLIDES RIGHT OUT. THEN YOU CAN REMOVE THE PIN CONNECTED TO THE GREEN WIRE, PIN#11, IT IS ON THE BOTTOM ROW IN THE CENTER. PUT THE DIVIDER BACK IN AND RECONNECT THE HARNESS!

OR YOU CAN JUST CUT THE GREEN WIRE - LAZY.:grinyes:

PRESTO NO MORE LIGHT!!!!!

Hey Jarben1,
Are the instructions from Arnott Industries incorrect for 1997 :confused:
Is "unplugging the module" as referenced incorrect? We need to know for future questions on this subject.

YES, SIMPLY UNPLUGGING IT WILL TURN OFF THE LIGHT, BUT IT ALSO DISABLES THE STEERING CONTROL THAT IS OPERATED BY THE SLIDE LEVER TO THE LEFT OF THE STEERING COLUMN. REMOVING THIS PIN#11 FROM THE HARNESS DISABLES THE CHECK AIR SUSPENSION LIGHT WITHOUT INTERFERING WITH THE STEERING TENSION.

HOPE THIS HELPS.

To confirm for 1995-1997:

You needn't remove the Glove Box, unhook it from the right, squeeze the sides to release and let it hang out of your way. Behind the Glove Box, mounted to the Heater Unit is a connection with two plugs, one GRAY, one BLACK, each about 2". On the BLACK connector, midway, is a GREEN wire (this is pin #11). Cut this wire to disable "Check Air Suspension" light.

And to prevent the Air Compressor from ever coming on again, just remove the 30A FUSE (#35 I believe) for the Air Suspension from the Fuse Box under the hood. I also left all of the hardware in place for the original Air Bags, I just used Zip ties to secure the connections to whatever was handy and away from the exhaust. As for the ride, I can't tell the difference; it's still like driving a Barcalounger down the road...

For those of you with a '98 on, you are out of luck if you wish to disable "air suspension" indicator on dash. It is controlled by the ECM/BCM, and short of reprogramming the computer, there is no way to turn out the light. I just got used to it being there...

Perhaps removal of the BULB on the Instrument Cluster for '98 and on?

Yesterday my compressor bit the dust...The bags were fine, however after careful reasoning I decided that I would just change the springs. I called the local part store, and got the coil springs for $85.00 for both. I let the guy at the counter know how I dreaded laying on the cold ground to repair. He called a buddy who's in my drive way as I type this, replacing the springs for $50.00!!! This sure beats the dealer quote of $1200.00!!!

I will be doing the easy part...disengaging the Check air suspension light...Thanks for the help on how to do this.

You will be quite pleased with your decision. Knowing that the ARS can never fail again is comforting to say the least. You can even sell the Air Springs on EBay for a few dollars; I sold my Compressor and Air Springs for $62 so the cost to 'repair' my ARS was about $21. I did make it a point to list that I did not know which component had failed although I had suspected an Air Spring.

I might have paid someone $50 to do it also.

I have to say, I have owned this car since day one. Bought it brand new while on vacation after being hit by a truck in Ocean city NJ. in 1996. The trucking company allowed $20,000 budget, and I think I paid like $6.000 money difference on a left over Mulberry (pinkish-reddish) 1995 Town Car Signature with 10 miles on it. I still remember the sales man asking me, "Why does a 25 year old want an old persons car." I told him they are not only for the seniors, and they last forever, and it has. This was the first real problem I have ever had with my 80,000 mile Town Car. I was on the fence about changing the spring out, however if I sell it for a new 2010 this will insure the next owner can get 80,000 mile of trouble free driving from the springs.

For the sake of any new owner or an idiot mechanic attempting to sell parts that would not be needed, I placed a sticker on the ARS Switch in the Trunk, in the under Hood Fuse Box and on the Heater Unit indicating the ARS has been removed and replaced with reliable Coil Springs.

For 1995-1997: Behind the Glove Box, mounted to the Heater Unit is a connection with two plugs, one GRAY, one BLACK, each about 2" just to left. On the BLACK connector, midway, is a GREEN wire (this is pin #11). Cut this wire to disable "Check Air Suspension" light. You don't want to unplug the BLACK Connection as that will disable the Assisted Steering if your vehicle is so equipped. Reattach Glove Box.

It should be the GREEN wire that is midway in the plug to the right, where a YELLOW wire is on the right and two EMPTY spaces to the left. This is the wire I cut. Give yourself plenty of room to splice it back if needed.

Now that it is unplugged, cut the GREEN wire and plug it back in. The plug does more than just illuminate the Check Air Suspension light. If you have Speed Sensitive Steering, you're just disabled it too by unplugging that connection.

Already done...pulled the red center piece out, the pulled the green wire out of the back of the plug. re-connected the plug and bingo the light is out and the steer control is unscathed...

However all has gone bad this morning...not with the light but with the passenger-side mirror. I was backing out of the garage, not paying attention, when I herd the scraping sound of the mirror being pulled of by the trim that surrounds the door opening. I was able to screw it back on with large screws though...Now this is going to be costly, trying to find a new mirror...Not at all happy with myself.:banghead:

I have confirmed with a Federal Mogul technical specialist that their instructions with the coil conversion kit are NOT correct for 1998 Lincoln Town Cars and later models. Because the air suspension system is now linked with the Electronic Variable Orifice Power Steering and data is sent from the Air Suspension/EVO Steering Module over the Multiplex Communication Network there is now NO WAY to shut off the air suspension warning message after converting from rear air springs to coil springs. He assured me that the coils work well after the conversion, but one has to be willing to live with the warning message. He also told me that they have requested the coil manufacturer (Moog) to correct their instruction sheet to reflect this reality on the newer models, but so far they have chosen to continue with the old instruction sheet.

Remove the on off switch in the trunk, cut both or remove the wires from the switch, bare each wire and tape them together. No more warning light.

Cutting the wires to and from the air suspension switch and removing it sounds like an easy fix. Unfortunately, a quick examination of the electrical diagram for the air suspension system of the 1998 Lincoln Town Car shows that the switch merely opens that particular circuit, so turning the switch off does precisely the same thing as removing the switch from the circuit.

As I stated in a previous comment, the technical specialist at Federal Mogul assured be that while the Moog CC865 coils they manufacture will very adequately replace the air springs of the Lincoln Town Cars from 1989 onward, they have found NO WAY to turn off the air suspension warning message on newer models beginning with 1998 because those models use the multiplex communication network to communicate with the instrument panel. (According to the electrical diagram, that panel communicates various important data, such as vehicle speed, driver's door ajar status, passenger's door ajar status, and odometer.) The technical specialist told me that their company had contacted the car manufacturer with the request that they revert to the previous configuration, but no change was forthcoming.

The bottom line--conversion from air springs to coil springs will definitely work but, for models beginning with 1998 and newer, the warning message will remain on.

We just replaced the suspension on my dad's 1995 Lincoln Town Car, and the instructions for disabling the Air Suspension Warning Light were not very clear. When I looked on this forum, I didn't find anything conclusive.

As a matter of fact, on his car, the connector had two white plugs on them - not a black and a grey. We first tried disconnecting the grey connector just to see if the light still came on, and it did. Plus, the black connector did not have the green wire with a light green stripe, but the white connector did.

So, we tried the white connector and that was correct. So I plugged it back in, and clipped the green / lt green wire and taped the ends. All is working. I'm going to (try to) post a photo or two as well.

Here's a photo showing the location of the module. (https://flic.kr/p/mBkoYw)

On my 1996, one of those plugs was a light grey color. Good job on deducing which green wire to cut.
