Known issues on the 1986 Fleetwood. Five recalls are on federal record for this model year. A replacement fuel filter connector could seat the O-ring incorrectly, risking a fuel leak that could ignite in the presence of a spark. Limousines built by Empire Coach were flagged for a missing or incomplete vehicle alterer's label, putting them out of compliance with federal labeling rules. Rear-facing seating positions were built without the required type 1 lap belts, a shortfall from FMVSS 209 and 210 that could leave occupants without restraint in a crash. The push-pull headlight switch could develop electrical contacts that make the circuit intermittent, causing the headlights to flicker or go out suddenly and cutting visibility without warning. A wiring harness under the instrument panel could go unsecured and interfere with the accelerator lever, keeping the throttle from returning to idle and causing a loss of accelerator control. Owners have filed 7 complaints for the year. The factory diagnostic and repair procedures behind each of those systems are here.

Whether you're tracing an intermittent headlight circuit, checking the fuel filter connection, or servicing the accelerator linkage, it keeps you on the OEM procedure and the correct specification for your specific 1986 Fleetwood.
