Suspension problem
1990 Cadillac Deville V8 Front Wheel Drive Automatic 170k miles

I have an air ride suspension on my 1990 cadillac deville. Im aware of the leveling arm underneath behind the right wheel, which controls the lower/lifting of the vehicle. My question is that Im trying to figure out what part is responsible for the air ride because everytime I try to raise it up, it will not hold its lift and it will eventually sag back down. Im guessing its the struts but Im not a mechanic- if anyone knows what part I need to replace to fix my air ride situation, I would appreciate it. Also what part(s), brands and where would you recommend purchasing.

We use a spray bottle with soapy water to find the air leaks, they can be the lines, the struts, and the compressor not turning on.

Well I know that the compressor is working, at least to my knowledge because you can hear it and after a couple of minutes it will stop and it would raise up. Just doesnt hold, so your saying maybe the lines or the struts. Is that where the air is being adjusted for the rear? Thanks for your help

Spray strut air spring, and air lines, bubbles will be visible if it's leaking. Also look for any oil on the outside of the struts, this indicates it's leaking as well.

Does any company make a strut that you can use without the air suspension? I would like to bypass the air if possible and use just a gas charged strut if possible.

Thanks!
