Cadillac Seville STS Problems
Improper HVAC Temperature and/or Air Delivery Due to Failed Mode Door Actuator
One or more heater & AC (HVAC) temperature and/or air delivery mode door actuator may fail, resulting in improper temperature or air delivery. If this occurs, fault code(s) should be stored in the HVAC control module which should assist in diagnoses.
ABS Light Due to Control Module Failure
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.
Trunk Lid Won't Close Due to Trunk Pull Down Switch Failure
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 Parking Brake May Not Automatically Release
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.
Coolant Leaks From Water Pump and Radiator
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.

Cadillac Seville STS Stories
Beautiful to behold. Always silky smooth to drive.
Fifth generation Seville touts a K style Oldsmobile Aurora body, the structure much stiffer with front-drive drivetrain featuring the muscle Northstar V8 and 4T80-E four-speed automatic (which is probably its worst component)
I miss the wreath crest, but otherwise, the lines are striking and the crimson red exterior and cream leather interior are eye catching.
Paid too much - the dealer wore a starched white shirt and cuff links in a Italian suit and proclaims he's just a country boy. KBB says it's worth $5K but you couldn't match the luxury feel and the dependability for that.
Well,one day at lunch time I went a eat at a fast food place and went inside to get my meal,turned the car off as always. when I returned I put the key in the ignition and turned the key and got nothing,no click,not anything. All the lights come inside and out, so I thought it was the starter,got a new one and put it on, battery was low so another battery to help start the car,it turned over but would not start, so I asked my friend next door for bust and when he put the cable on the and I tried starting it, it wouldn't say anything at all,I don't understand what could be wrong!!
I was driving to school no less then 10 minutes ago, every thing was fine. THen the low oil light went on. I changed it last week so i knew that was off. Then the power steering went off, i managed to turn into my college, then fuel injection failed. Everything still worked, i turned the car off then back on, and every thing worked. I am taking the old girl to the shop, but does anyone have any ideas why this happened.
I own a 1998 and 2003 Cadillac STS, both have had oil leaks and driver's seat heater failure at approximately 85,000 miles. The resealing of the crankcase and oil pan requires removing the transmission. Paid $1,500 each to reseal the engines. The seat heater requires pulling the cover and cushion back and splicing the broken wire feeding into the heating pad. I paid $245 to have a repair shop do this on my 1998 STS. I did it myself on the 2003. I use a single strand, out of a light gauge electrical wire, to make the splice. Then wrap the splice with electrical tape.
