1993 Cadillac Seville STS Problems

Heating & Air Conditioning -- Verified

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.

Brakes -- Verified

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.

Miscellaneous -- Verified

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.

Engine -- Verified

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.

Brakes -- Verified

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.

when I brake pedal and the car is hard not to

overheating issues

I love the way my car drives, smooth and comfortable and everything inside works. Only problem is the pretty fake wood trim around the gear shifter is breaking away. If I keep my speed below 65 I get between 25-35 mpg with cruise on, of course, depends on the road grade too. It is costly to maintain the way it needs.

I have a 1993 Cadillac sts and it is over 17 years old...it still runs but i have had to do a lot of replacement work on it recently. The transmission will give you issues once you pass the 170,000 mile mark but the engine is the best I have ever seen (except the slow oil leak of northstars). I love this car but it is expensive to repair if not maintained. I will drive it until it wont drive anymore.
