Known issues on the 1987 Eldorado. Two recalls are on federal record for this model year. The first covers replacement fuel filters supplied for the fuel system: a connector not built to specification can keep the O-ring from seating correctly on the fuel line, which can produce an inadequate seal at the connection, a fuel leak, and, near an ignition source, a fire. The second covers the headlight switch: with the Twilight Sentinel system on, faulty electrical contacts in the potentiometer can create an intermittent circuit that cuts the headlights and instrument panel lights without warning, reducing driver visibility. Owners have filed 7 complaints for the year. The factory diagnostic and repair procedures behind each of those systems are here.

From tracing a Twilight Sentinel fault to inspecting a fuel filter connection, it keeps you on the OEM procedure and the correct specification for your specific 1987 Eldorado.
