Cadillac Repair/shocks for 88 caddilac fleetwood


i just bought an 88 Cadillac fleet wood and have a couple questions regarding the shocks and air ride suspension. First off the air ride suspension system hasn't worked since i got it and the "car is leveling" light is always on in the information center.I was told that it was disabled because if hooked up it would constantly kill the battery.The ride is extremely rough and it hits hard going over ANY kind of dip causing lots of bouncing. Is this a result of that being disengaged? Second, do I need to replace the shocks and struts in order to fix the hiting so hard and the bouncing? If so what all do i need to replace? thank you very much for your time!


When the system worked, these cars would ride very nice. When there was a problem, it was a real problem.
The battery goes dead because the compressor didn't stop running because it is trying to compensate for a leak.
Because of the age,the lines could be broken as well as the shocks leaking.

See if a parts store has aftermarket Moog or Monroe shocks for it. The Cadillac version is just to expensive. Check to see in the new shocks come with New plastic lines or if you have to get them somewhere else. Install the lines and shocks and hook to compressor.
Leak test with soap water. If bubbles come out, you have a leak test.
If all is good, compressor will run until shocks are up and shut off, no longer draining battery.

Alarm system questions cannot be answered on this forum. These systems are not what I can answer. Without being physically at the vehicle and not knowing what kind of electrical service has been done on the vehicle, there is no possible way to give an accurate answer over the internet. My expertise is in Ignition/key based anti-theft systems. These issues include GM VATS (resistor chip in key blade) PASSLOCK (MRD)-ignition lock rotation based, no special ignition key and the PKIII Transponder (computer chip in key) systems. These systems are not alarm based and are integral with the starting of the engine. This is why I cannot diagnose alarm problems without physically looking at the vehicle: Alarm systems are a completely different annimal than ignition key/lock based anti-theft system. Many alarm questions come from vehicles 10 years old, and since older, many hands that had been involved over the years.I am an expert in all GM factory (ignition/key based)systems. Alarm system questions pose to many situations beyond my knowledge as to what has been done to the vehicle over the years. Some guy may have actually wired the stereo into the alarm system. Who knows? Over my past 30 years in vehicle wiring repair, I have seen unbelievable wiring disaters done by guys that consider themselves "mechanics." I have seen stereos and alarms intalled using surgical tape. I have seen modules burn up, un-fused circuits, wiring jambed between the doors and even lamp cord used for a starter kill. To answer alarm questions over the internet without examining the vehicle is like asking; What does it take to remove a dent?
