rockfangd Posted February 18 Report Share Posted February 18 Hi All. I have had several Cadillacs over the years, and they all seem to share the same issue with the air ride compressor failure. I finally replaced the shocks on one of mine with the coilover conversion shocks. I was hoping I would like them but I do not. Car was on its third air compressor failure and I got tired of crawling around under the car working to replace it. I am strongly considering reinstalling the Arnott shocks I had installed, relocating the compressor to a useful spot, and getting the system working again. I am willing to try aftermarket setups if it is reliable. The air lines are not 1/8" though. They are actually smaller. 4mm?? 1/8 is the typical size. So I would have to get conversion unions or replace the lines all the way to the shocks. Car I am looking to entertain this for is my 1997 Seville. Thanks all Quote GM FAN FOREVER Nice, clean, luxury= fine automobile Link to comment Share on other sites More sharing options...
Bruce Nunnally Posted February 18 Report Share Posted February 18 Do you have a feel for why the compressors are failing? Quote Bruce 2016 Cadillac ATS-V gray/black Follow me on: Twitter Instagram Youtube Link to comment Share on other sites More sharing options...
rockfangd Posted February 18 Author Report Share Posted February 18 original units failed because the exhaust valves failed. I repaired some but usually still short lived. Aftermarket ones the main hot wire fails just inside the motor. Must be a weak connection there. Power comes to motor but no response from motor. It is on its second Dorman one and they both failed in the same way. I had replaced the shocks and lines when I installed the first one.

rockfangd Posted February 19 Author Report Share Posted February 19 I am contemplating trying the Arnott one for a 2002 Deville. Looks like the same unit except the electrical plug and the 2 ear mount. They do not offer one for the E/K platform Quote GM FAN FOREVER Nice, clean, luxury= fine automobile Link to comment Share on other sites More sharing options...

rockfangd Posted March 13 Author Report Share Posted March 13 Still thinking on this one. I am so temped to put a compressor in the trunk, Make my own extension harness, and run one line from compressor in trunk to a Tee underneath to split to each side. Being these lines are so small it is difficult to find anything. Quote GM FAN FOREVER Nice, clean, luxury= fine automobile Link to comment Share on other sites More sharing options...

rockfangd Posted March 16 Author Report Share Posted March 16 Could you be more specific? Like oem one or aftermarket You may be on to something. If I can replace the lines with aftermarket I may be able to do whatever I want, just need to figure out compressor side Quote GM FAN FOREVER Nice, clean, luxury= fine automobile Link to comment Share on other sites More sharing options...
brmurph Posted March 21 Report Share Posted March 21 I have had a couple of dorman compressors, neither of them lasted more then a few months and their catalog was wrong for the 98 Deville. So far I have still been able to get OEM compressors for both the 98 and 2004. For the 2004 Deville I bought a compressor for the 2006 + DTS as they are still available. The compressor was the same as the 2004 but I did have to modify the electrical plug, can't remember if I switched out the end with the 2004 or if I just had to switch a couple of wires (I think the latter is correct), it also came with the airlines that worked fine for the 2004.

rockfangd Posted Saturday at 01:00 AM Author Report Share Posted Saturday at 01:00 AM Well I decided I am going to replace compressor with a oem one with a new dryer. Going to have to reinstall the air shocks. Fingers crossed. Quote GM FAN FOREVER Nice, clean, luxury= fine automobile Link to comment Share on other sites More sharing options...
