2009 Mercury Grand Marquis with 40k miles

Check Air Suspension warning light came on. I also noticed that the sound that I heard when I started the car (probably air compressor?) has stopped.

The rear of the car seems to be sitting low but I am not sure about it.

Can someone recommend a reliable mechanic for helping solve this problem?

Thanks for your advice.

Welcome from Painesville.

Not sure what your mechanical ability is, but if you can jack the car up and look underneath, sometimes the little arm that acts as an air ride sensor comes unhooked. It looks like this:


Happened on my Marauder and has happened to others as well.

I was thinking of moving this to Suspension but, if what I suggested above doesn't pan out and you just wanna pay to have it fixed...Regional would work.

Thank you from Solon.

Unfortunately, my mechanical ability is poor. I will see if there is someone who can help me with jacking up the car and taking a peek.

What do you mean by, Regional? I don't understand.

Ignore what I said...I didn't notice you'd posted the same question in the Suspension forum.

Good morning,

The mechanic says that it may require replacing the air bag suspension with a coil suspension. He suspects that the air compressor may have gone bad.

Total repair estimate is $534 with Monroe coil suspension. Is the estimate fair? Is Monroe coil suspension good? If not, which coil suspension would you recommend.

I assume he ruled out the ride height sensor? Your compressor won't make a peep if it is disconnected.

Either way, you do not need to replace the air suspension system entirely. If it truly is the compressor, Arnott makes a replacement for $222.80.

Overall, the ride height system is rather dependable.

$534 is a lot of money to take out the air bags and put coils in. If you're mechanically inclined google your model and "check air suspension" there are many helpful threads on the subject. Not sure about the 2009 but there should be a relay under the hood that could be bad.

If he can't diagnose the air bag system, I wouldn't want him working on it.

These systems are actually fairly simple and incredibly reliable. My Crown Vic has 225k on its air suspension, and the only 2 things replaced so far are the rear air bags, and a compressor (which I suspect wasn't needed, just replaced it because it was getting noisy.)

Do NOT convert it to coils. The car will give you an error message on your dash saying the air suspension is faulty. Plus, to fix your issue, it will be cheaper than converting to coils, and you'll maintain your great ride. Converting to coils does worsen the ride.

Might be time to find someone else to work on your car who is familiar with the rear air suspension, or find a local CVNer who is willing to help.

Also, that price is a complete and total ripoff.

How do I go about finding a local CVNer who might be willing to help troubleshoot and/or fix this problem for a price?

No, he has not inspected the MGM yet, therefore has not ruled out the ride height system.

My usual mechanic told me that he is not interested in this job because of the complexity. One other mechanic told me something along the same line. So, its been a bit discouraging. Fortunately, I have an old backup car to use, therefore I am not pressed for time.

I can't believe I missed this but...
Did you check the switch in your trunk to make sure it is turned to the 'ON' position?

Are you (and a friend/family member) able to jack up the ass end of the car at all? Not sure what your situation or abilities are and definitely not trying to ask super-personal questions.

Anyway, if you can, I can try to explain how to check the sensor. It's...painfully easy once the car is up.

I will jack up the car! No, I won't get offended if you ask super personal questions.

I have a hydraulic jack. I used it about 15 years back! I just have to make sure that I place the jack properly. Hope I don't have to crawl underneath the car, never done that.

Please, USE JACK STANDS when lifting a car! If you don't have some, head over to a Harbor Freight and spend $30-40 on a pair. laugh

You do not have to crawl under the car to jack it up, but you do have to crawl under the car to check the sensor.

There are jack points marked on your rocker panel covers (the plastic bits underneath your doors on each side). Look for the little arrow marks...those are jack points.


Really surprises me that you're experiencing resistance on this job from mechanics. If it was truly the compressor, it's not a hard fix:

I have a tendency to get my shoulder dislocated, so I do not want to take a chance by crawling under the car.

The two mechanics who refused to take Mercury Grand Marquis work have been in the business for more than a decade. In my opinion, they are skilled and trustworthy but they refused to touch my Mercury Grand Marquis.

The installation of the air compressor, as shown in the video, does require multiple but uncomplicated repair work. I don't understand their reaction. Maybe they just want to work easier work.

The mechanic who quoted $534 for installation of the coil system is charging for 3.5 hours of labor.

I have no idea what my schedule, or the weather, will be like on Monday.
However, if you're free during the day (like, before 2pm) on Monday and my schedule works out and it's DRY AND NOT CRAPPY...I might be willing to drive down to Solon and throw it up in the air.
Unfortunately, I won't probably know much about my schedule until Sunday evening, so there's that.

I would be very grateful to have you look at my car. My schedule is flexible and am available on most days.

According to weather dot com, high temperature is 39 degrees, mostly sunny, zero percent chance of precipitation, wind at 5 mph.

I have messaged you my phone number and address.

IMHO your regular mechanic is a chickensh!t. RAS is a very simple system to diag and repair as opposed to the 4 wheel systems. If it needs a comp. Ford MSRP is $698.08 but I cut CVN'ers a break, I can sell you one for $523.56, I'll get back to you with labor when service gets back to me.

It doesn’t need anything.
Working fine upon arrival.
Think it was just a fluke. Car is clean and bags are mint.

Joe, if you ever need a Ford-specific part, this is an incredibly solid lead:

I don't think I am going to take my cars to Lube Stop for oil changes anymore. If you had not told me that they had installed oil filter that's not the standard for my MGM, I wouldn't have known about it.

Thanks very much for recommending the oil spray, I have a friend who does this for his cars but I didnt want to impose on him because of his age. So, I am happy to know about Long's Oil Spray. Much obliged.

If he can't diagnose the air bag system, I wouldn't want him working on it.

These systems are actually fairly simple and incredibly reliable. My Crown Vic has 225k on its air suspension, and the only 2 things replaced so far are the rear air bags, and a compressor (which I suspect wasn't needed, just replaced it because it was getting noisy.)

Do NOT convert it to coils. The car will give you an error message on your dash saying the air suspension is faulty. Plus, to fix your issue, it will be cheaper than converting to coils, and you'll maintain your great ride. Converting to coils does worsen the ride.

Might be time to find someone else to work on your car who is familiar with the rear air suspension, or find a local CVNer who is willing to help.

Also, that price is a complete and total ripoff.


Liberty Ford in Solon quoted a rate of $129/hour to to diagnose the air bag system.

Today, the check air suspension light came on, again. The compressor is not kicking on. So, the suspension worked well for about 100 miles.

I also noted that the sound from the compressor (when it was working) was a little off. Any ideas or suggestions?

Just replace it all with coils and new shocks. I just did yesterday. Although I used springs that lowered it the ride really hasn't degraded.

Which brand coils and shocks did you use?

I'm not a fan of coil conversions. That is not to say I haven't done them, but the air suspension setup is just better in several ways. If you do convert it to coils, please, do not just chop up the lines and wiring like whoever converted my Town Car did, made putting the air ride back in it more of an journey than it should have been. Whenever I do them, I simply unplug things and disconnect the lines and zip tie them up out of the way, takes maybe an extra 10 minutes, but would save a ton of time if you ever decide to put it back.

My preference is to use OEM springs from a coil sprung car. The ones that come with the "conversion kits" are too $$ and the 2 I've experienced have been too harsh. Before I put the air ride back in my Town Car, I swapped out the coil conversion springs for a set of factory coils from a CV, those rode 100x better, tho they did sag with the extra weight of a Town Car so it sat a bit low.

My opinion: If you really want the minimum-cost solution, coils will get you there. If you ever plan to do anything like put lots of heavy stuff in the trunk or tow, fix the air suspension.

I got rid of a GS and replaced it with an LS HPP because I wanted the stiffer suspension and RAS. Wouldn't ever go back.

If anyone knows a skilled forum member, within 200 miles of Cleveland, who is willing to do the conversion for me, please let me know. I would be happy to pay for this favor.

I have a severe problem with my shoulder so I can't do this work myself. Further, i just don't have the knowledge or skills.

The sixth mechanic I contacted, after five refusals, took the job. Going forward with the conversion, could not deal with the unreliability of the air suspension.

Just seeing this now...sorry you're having issues again. System looked really good from what I could tell, so I have to believe it's a fixable thing. But hey, do what ya feel and switch to coils if you want.

You are absolutely right Adam. My situation has also changed a bit and I had no choice since several mechanics refused to troubleshoot the air suspension.

Wanted to share my experience with the conversion. Is there a difference? Yes there is. Air suspension was better than coil and springs. I would guesstimate that the difference is about 15%. I am okay with the loss of air suspension but in my case, I gained reliability.

One silly question, I want to check the coolant in my 2009 MGM, where is the radiator coolant tank located?

This system is easy to fix.

Go to Arnot for the parts. I would get a pair of air springs, the solenoids should be replaced as PM as well. Your compressor is also bad from having been overworked. Get that as well. Replacement of air ride springs is very easy. Also the air compressor lives under the air filter box. Remove the air tube and air box to get to the compressor underneath. your biggest issue would be corroded bolts. you may need to cut out the old rusted bolts and replace with new. make sure you get an air drier with the compressor. There are writeups here on this site that have step by step instructions. with a couple of jacks, hand tools, and some patience one can do this job easily.

He hasn't logged in since making his last post and already converted. I doubt he'll be back, or change back to air.
