96DeVille Posted March 21, 2004 Report Share Posted March 21, 2004 I wanted to know if anybody knew the cost of a suspension compressor (underneath in the rear) would cost me for a 1996 DeVille. It makes a lot of noise and I wanted to know if it is an expensive repair, and also if there are any "quick fixes" to hush up the noise. I greatly appreciate any feedback on this dilemma, thanks.

msilva954 Posted March 22, 2004 Report Share Posted March 22, 2004 Someone more knowledgeable could chime in, but if it is too expensive you could just switch to passive rear. Link to comment Share on other sites More sharing options...
Ranger Posted March 22, 2004 Report Share Posted March 22, 2004 I am not looking at a service manual as I am at work right now but I am pretty sure those ELC compressors are serviceable. You may not need to replace it. Find out what is makeing the noise first. Link to comment Share on other sites More sharing options...
96DeVille Posted March 22, 2004 Author Report Share Posted March 22, 2004 How could I switch to passive rear? And also I checked underneath the car and it sounds like the motor is clicking when it turns on. I appreciate your help, thanks. ADT Security Services, Inc.

Ranger Posted March 22, 2004 Report Share Posted March 22, 2004 Switching to "passive rear" means replacing the struts with non-air struts and disabling the ELC. If it's clicking, it is getting the signal to start. Obviously the problem lies with the compressor. You'll need to figure out if it is the electric motor or the compressor. Again, I am not looking at a manual but you may be able to just replace the part that is bad. Also check the connections. Being under the car it is subjected to some pretty harsh conditions.

Dan Posted March 22, 2004 Report Share Posted March 22, 2004 The passive shocks do not get rid of the ELC. They are air ride shocks just like the electronic ones. Passive means that the dampening in not electronically controlled. The ELC is a different thing all together. The best places to buy a new compressor is: http://www.gmotors.com http://www.gmpartsdirect.com http://www.partszoneonline.com/ Link to comment Share on other sites More sharing options...
Ranger Posted March 22, 2004 Report Share Posted March 22, 2004 Dan, Unless I am misunderstanding this msilva954 said "passive rear". I take that to mean rear shocks/struts without the ELC leveling capability as opposed to "passive struts" which as you stated means electronically controlled dampening (Probably not on the '96 Deville). "Passive" rear may be a bit misleading. Link to comment Share on other sites More sharing options...
Dan Posted March 22, 2004 Report Share Posted March 22, 2004 Oh, I thought he meant passive struts. GM doesn't make a air shock replacement kit. I guess it it theoretically possible to have someone fabricate a new "strut cartridge" assembly to replace the rear shocks. (the OEM springs cannot support the weight of the rear of the car without air shocks) But this would be really expensive, I would just buy a new compressor Link to comment Share on other sites More sharing options...
Ranger Posted March 22, 2004 Report Share Posted March 22, 2004 I agree. I would repair or replace the compressor and retain the ELC capability. Link to comment Share on other sites More sharing options...
