Well, I found another STS that I am interested in purchasing, this time it is a 2001, BUT, The serice ride control message is illuminated when I start the vehicle and I notice the car down lower in the back when it sits for a while but when I start it, the back raises almost to where it should be. Would this be that the rear shocks are bad and leaking or a sensor or something else that is causing this?? The vehicle only has 68,000 miles. Any help is appreciated. Rich.
back sitting low COULD be a leak in the air suspension, the service ride could be either the suspension needs to be replaced or was replaced with passive and not bypassed. I would see if you can get some maintenance history and pull the codes, if you can use this as a negotiating tactic to get it for cheap it might be worthwhile...show the owner what it would cost to have Cadillac replace the suspension

Re: Service ride control message on 2001 sts
When you start the car, after 8 - 10 seconds, you should hear the level ride compressor in the right rear come on for 3 - 5 seconds to prove out and level the car. If that happens, open the trunk and 2 of you sit on the trunk opening lip. The compressor should again come on and level the car. Now, both stand up - stick your ear down by the RR fenderwell - and you should hear air escape from the exhaust valve built into the system. The car will return to level. If it sags down within a week of sitting idle, there's a leak somewhere - shock boots, air lines, compressor/drier/valving, and that will set a fault code. As ryannel said, learn to pull your own codes.......it's all built in. You don't need an aftermarket scanner. Use the "search" feature up in the blue bar ^^^, select threads, and type in "level ride compressor". Hold onto your credit card: $400 part(s) and $200 labor, compressor only. Shocks and air lines = another $900 or so.
