Question about 1998 Cadillac DeVille

I think that my 1998 Cadillac air suspension system is going bad

I think that my air suspension system is going bad on my 1998 Sedan Deville. When I turn the key to the battery position (without cranking engine) I hear a rattling noise from the rear of the vehicle and once I start the engine the noise remains but sometimes goes away. Still yet it is intermittent when driving the vehicle. Do I have to replace the whole air suspension system in order to solve this problem? Thanks for the assist.

I had a problem with my '98 Deville. I had a lot of issues with the air shocks and all the other electronic stuff that goes with that. I called the dealer, and they wanted $3500 to fix it!!! I found www.Strutmasters.com and they converted my car to a "passive" suspension, which bypassed that whole computer thing. Now I have a lifetime warranty, and I am VERY satisfied with the ride. The best part is that it only cost $800 and I got all new suspension! I highly recommend them for your vehicle!

How to remove air suspension pump?


Replacing your Cadillac DeVille DTS electronic shocks with these reliable non-electronic shocks is a simple installation procedure. Cadillac air suspension fails because of rubber dry rotting, and then leaking. Your air suspension compressor will eventually fail because of this. Cadillac shocks in the front fail because of the seals in the Cadillac shock wearing down over time. They eventually leak, losing its dampening ability needed for a safe and smooth ride. Try cadillac dealership for a little more info.

I have a 1996 Cadillac Sedan DeVille. This spring...


If the a/c does not engage as a result of the electronic control system in your 1996 Cadillac, the climate control system may need to be replaced.

However, if the problem is being caused by low charge of R134a in the system, have the system charged before changing that electronic part.

I have never seen a Cadillac Climate Control System do this, which leads me to believe that it may be more electronic than refrigerant pressure related.

If the refrigerant pressure was low in the system, the climate control system should still stay on 'auto' mode, I think, and simply blow warm air.

What is the possible problem when my 98 deville rear suspension is jacked up to the top all the time? is there a way to reset it This occured after the last time I had the car in for repair and then...


I have seen this before. They put car on lift which lets suspension drop. When they set it back down the Air ride leveling rods get stuck and think they need to stay full. Like what was already mentioned, check your levelers located next to your suspension air bags to see if they are stuck.
