Known issues on the 1993 Seville. Two recalls are on federal record for this model year. The first covers the fuel feed and return lines to the engine fuel injection system, which were not fully assembled and locked and can work loose, causing a fuel leak in the engine compartment that risks an underhood fire near any ignition source. The second covers the air conditioner compressor clutch assembly, which can contact the auxiliary engine oil cooler outlet hose and wear it through, leaking engine oil into the engine compartment where contact with the hot exhaust can start a fire. Owners have filed 46 complaints for the year. The factory diagnostic and repair procedures behind both systems are here.

From tracing a fuel line leak to checking A/C compressor clutch clearance, it keeps you on the OEM procedure and the correct specification for your specific 1993 Seville.
