Known issues on the 1999 Seville. One recall is on federal record for this model year, covering the alternator: an electrical short can develop inside the generator even with the engine off, and that short can spark an engine compartment fire capable of spreading to the rest of the vehicle. Owners have filed 75 complaints for the year. The factory diagnostic and repair procedures behind that charging system are here.

Whether you're tracing a charging-system fault on the Northstar V8 or working through a routine service interval, it keeps you on the OEM procedure and the correct specification for your specific 1999 Seville.
