Known issues on the 1983 Seville. Three recalls are on federal record for this model year. The first covers the fuel system: the fuel filters were produced with an incorrect threaded fitting, similar enough in size that the fuel filter may appear to be correctly threaded onto the fuel line. The second covers the rear window defogger circuit: the fusible link protecting electrical components run through the ignition switch could come open during defogger operation, and with the Twilight Sentinel switch on and the headlight switch off, an open link results in a loss of headlights. The third covers the windshield wiper motor: the noise suppression capacitor in the wiper motor relay may overheat during operation. Owners have filed 2 complaints for the year. The factory diagnostic and repair procedures behind each of those systems are here.

From swapping in a correctly threaded fuel filter to tracing the fusible link behind an intermittent headlight failure, it keeps you on the OEM procedure for your specific 1983 Seville.
