Known issues on the 1986 Cimarron. Three recalls are on federal record for this model year. One covers a replacement fuel filter connector that was not manufactured to specification, so its O-ring may not seat correctly on the fuel line, creating an inadequate seal that can leak fuel and, near an ignition source, start a fire. The other two both cover the push-pull headlight switch, whose electrical contacts can allow an intermittent circuit that makes the headlights flicker or suddenly go out, cutting driver visibility in severe weather or nighttime driving without warning. Owners have filed 6 complaints for the year. The factory diagnostic and repair procedures behind each of those systems are here.

Whether you're chasing an intermittent headlight circuit or tracing a fuel line connection, it keeps you on the OEM procedure and the correct specification for your specific 1986 Cimarron.
