Known issues on the 1987 Seville. Two recalls are on federal record for this model year. The first covers a replacement fuel filter connector that was not manufactured to spec, so the O-ring may not seat correctly on the fuel line, creating an inadequate seal that can lead to a fuel leak and, near an ignition source, a fire. The second covers the Twilight Sentinel potentiometer, whose electrical contacts can cause an intermittent circuit that suddenly cuts the headlights and instrument panel lights, reducing driver visibility and risking a crash without warning. Owners have filed 13 complaints for this model year. The factory diagnostic and repair procedures for both systems are included.

Whether you're tracing an intermittent headlight fault or replacing a fuel filter connector correctly, this manual keeps you on the OEM procedure and the correct specification for your 1987 Seville.
