My usually trouble-free '97 LSC finally crossed the 100K mile marker this year (purchased in 2004 from the then-president of the National Lincoln Owner's Club). The all original suspension started sagging in the back over night, and the air ride suspension light occasionally came on. No big deal thought I, it's been a good 100K so it needs some love. Got all 4 new bags, new dryer, new compressor, new solenoids, and for good measure, new rear shocks, and had the local garage install everything. Seemed to go well for about 2-3 days, then had *exactly* the same issue: dropped in rear, light comes on intermittently and, when it does, the compressor doesn't kick on. Completely random too, no forecasting when it will work and when it won't. After chasing their tails for a couple of weeks, I picked it up from the local garage and took it to a local Lincoln dealership. The told me their computers wouldn't communicate with the suspension module (obsolete of course), so I tracked down and purchased a known good used module (TBSCShop) and shipped it to the dealership. Once installed...same exact issue. AND now they're telling me it wasn't the module, they just don't have the equipment to communicate with a car this old. After tossing over $2800 into the suspension to get it working, I'm at a loss now. I'm not interested in converting to springs, I'd really like to restore it back to it's former glory. Any ideas, or places in the Baltimore MD/Tri-state area that have the expertise to diagnose and really fix this issue? Any help is very much appreciated!
