On the 1991-1996 Buick Roadmaster, the Roadmaster Estate Wagon (and some sedans equipped with the F41 package) uses an Electronic Level Control (ELC) system with rear air-adjustable shocks (GM PN 22064630), a height sensor under the driver's side rear seat, and a hood-mounted air compressor. The rubber air bladders on the shocks crack and leak with age, the connector wiring under the body corrodes and breaks, and the height sensor fails — all of which cause the compressor to run continuously (sometimes after engine shutoff), pumping the rear of the car so high that ride and handling are ruined, or leaving the rear sagging. The original PN 22064630 shock is discontinued, complicating repair.
Diagnose first: inspect the height sensor wiring under the driver-side rear seat for broken/corroded wires, test the sensor, and check the air lines for leaks at the shock fittings. If the shocks themselves leak, the most common modern fix is a conversion kit (Strutmasters CADR3 or similar) that replaces the air shocks with passive gas shocks and either deletes the air system or splits compressor output to aftermarket air bags via a T-fitting. Replace the compressor relay or compressor if it sticks on. Many owners simply unplug the compressor and run conventional shocks to eliminate the system entirely.
