1995 Town Car with cracked/leaking air springs. Disabled module (trunk switch, jacked rear end, then supported rear frame structure while supporting axle on my floor jack. Slowly and partially lowered axle, but kept it supported on the jack. As it lowered I could hear the springs leaking! The cracks were at the bottom (axle) end, where it remains folded most of the time. Replaced both sides with re-man'ed air springs (Suncore, $85 each, new Goodyear bladders), replaced all four shocks too. Raised axle to make sure springs seated well on axle, bladders folded properly, then activated compressor to fill. After adeqaute fill, lowered car off jack and jack stands and let the system fill and level completely. It did perfectly, but compressor was loud, CHECK AIR SUSPENSION still illuminated. Replaced compressor (it was very hot when operating) as I figured it was bad, don't know how long bladders were leaking (its my parent's car) and figured it was near dead. New compressor cool and much much quieter. Still see the CHECK AIR SUSPENSION light (disconnected battery, reconnected, toggled switch in trunk a few times). The system seems to function perfectly; ignition on it operates compressor and raises vehicle inch or so (operates for ~10 seconds), shut down and it vents properly (after all closed). Re-cycle ignition, same results. Ride with passengers and it levels, remove passengers after a drive, shut down and close doors and it re-levels by venting. Sits evenly too. So it seems fine, no leaks, proper startup checks. It also holds height spot-on over several days with system de-activated (switch off). 30A fuse OK, relay OK. I don't have the Rontunda suspension code reader so I can't read or re-set the module. My backup pro mechanic does not have the reader either and said I did what he would have (as far as system checks go).. Will this go off after more driving or ignition on/off cycles? Only thing I can think that might still be bad is level sensor but I doubt it based on level adjustments working fine. Any tips or something I missed? I hate seeing the CHECK AIR SUSPENSION light! I have not unplugged any module connections yet, should I try that, unplug, wait, replug?
Thanks for your assistance!
