1996 Cadillac Seville STS Problems
The anti-lock brake system (ABS) control module may fail causing the ABS light to illuminate. Failed modules should be replaced to restore ABS operation.
The trunk pull down switch may fail causing the trunk lid not to close completely. Our technicians tell us that the failed switch can be replaced without changing the complete pull down motor assembly.
The water pump and/or the plastic side tanks on the radiator may leak causing a loss of coolant. The engine may overheat due to coolant loss. Continued coolant loss after external leaks have been repaired could indicate a blown head gasket.
The parking brake may not release automatically due to a failed vacuum switch or actuator. Our technicians tell us that if vacuum is supplied to the actuator when the transmission is in gear, the vacuum switch is functioning and replacing the actuator should correct this concern.

1996 Cadillac Seville STS Reviews
Purchased 1996 STS used in Spring of 1998 . Body and interior still perfect. No hint of rust , no rattles noise or wear on inside, Car looks, rides, drives as good as the day I bought it. Zero mechanical problems other than routine maintenance and oil changes. Engine uses no oil and runs perfect. Only real issue I have had is some electrical problems with power windows, climate control module, and traction control module. Best car I ever owned and plan to drive this until the wheels fall off. Have no desire to ever get rid of this car. Absolutely love this car!!!!!!
