1986 Sedan Deville air suspension

Hello fellas. I am currently helping my GF fix her 1986 Sedan Deville. I just did the front brakes, so now the car stops. Still, it is not safe for her to be driving around in.

I don't know anything about the system, but it apparently has an air suspension with a compressor for auto-leveling, I'm sure you are familiar with the setup.

Anyhow, When you start the car the compressor just runs and runs, and a light on the dash says something like "leveling" or something.

Anyhow, nothing ever happens and the car rides like it has no shocks.

I have tried some searching and read a little bit, and noticed it is popular to switch to normal passive shocks. Or struts. Is this car equipped with shocks or struts? I donno.. do you?

In either case, I was hoping for some quick advice on how to troubleshoot the air system, maybe there are some common problems like a leaky hose in a certain place, or something to that effect. If so I'd like to check that stuff first, maybe I could fix the existing system rather easily.

If not, I was hoping for some educated recommendations of possible alternatives, such as converting over, what brand/parts to use, etc.

Thanks in advance for any and all advice, and please, don't post if you are just gonna tell me to take it to the dealer, or a mechanic. I don't trust mechanics, they are nothing but trouble!

I do ALL my own wrenching :)

What You Describe Is An Air Leak, Either The Strut Itself Or The Supply Hose To It. Just Trace The Hose From The Pump Back To The Struts. I've Used Soapy Water Sprayed Onto A Hose To See If Bubbles Appear, Verifiying An Air Leak. Ck Areas Close To Exhaust Heat First Then Mis Routed Hoses That Are Rubbing On Something. Accually A Very Simple System To Fault Trace Because What You Describe Is Not Electrical In Nature. Once The Leak Is Found, Hopefully In The Hose, I've Used Copper Tubing And Ferrel Fittings To Replace The Damaged Section. If A Strut, Then Replace In Pairs. Good Luck, Bill.
Thanks for the input. I will attempt to find any leaks that are easy to replace.

If it is a strut problem, however, are there any recommendations for a good (read: CHEAP) replacement?? air vs. changing to hydraulic?

Autozone lists a Ryder replacement for $69 ea. I'm not sure if it's air or passive, but that's pretty cheap.
