Known issues on the 1998 Seville. Two recalls are on federal record for this model year. The first covers the alternator/generator: an electrical short can develop inside the unit even with the engine off, and the short can start an engine compartment fire capable of spreading to the rest of the vehicle. The second covers the windshield wiper motor, whose "low" speed function can go inoperative when switched down from "high," which can affect driver visibility if it happens in motion. Owners have filed 66 complaints for the year. The factory diagnostic and repair procedures behind both of those systems are here.
From tracing a wiper motor fault to inspecting the charging system or working through a routine service interval, it keeps you on Cadillac's own procedure and the correct specification for your specific 1998 Seville.
VEHICLE DESCRIPTION: PASSENGER VEHICLES. THE WINDSHIELD WIPER MOTOR 'LOW' SPEED FUNCTION CAN BECOME INOPERATIVE WHEN THE MOTOR IS SWITCHED FROM 'HIGH' TO 'LOW' SPEED.
IF THIS WERE TO OCCUR WHILE THE VEHICLE WAS IN MOTION, THE DRIVER'S VISIBILITY COULD BE AFFECTED.
DEALERS WILL REPLACE THE WINDSHIELD WIPER MOTOR COVER WHICH CONTAINS THE MICROPROCESSOR.
