1990 Cadillac Seville Problems

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.

Heating & Air Conditioning -- Verified

One or more heater & AC (HVAC) air delivery and/or temperature mode door actuator may fail. This can result in incorrect air delivery or temperature. If this occurs, fault code(s) stored in the HVAC control module should be available to assist with diagnoses.

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.

Drive Train -- Verified

The rubber section of an automatic transmission cooler line may develop a fluid leak . In some cases the leaking section of hose can be replaced. In others, the complete cooler line must be replaced to correct this concern.

1990 Cadillac Seville Reviews

the cars not bad the main problem is getting abs sensors for it and they go the suspension sys has hard to find noises but show no wear
the water pump will go at 95000 mi the studs snap on the engine front cover when replacing pump

I bought this 90 Seville in August 09 with 49,000 miles for $900.00 1 owner always garaged. The problem was it just sat for the most part. It needed a lot of work that I was not aware of when buying her. Transmission slips do to sitting and lack of maintenance , rear shocks leak and rattle, Turn Signals spring had to be replaced, Cruise Control don't work, A/C leaks only cause when converted to R12 they put the wrong valve on. She runs strong, rides smooth, and handles like a new 1990 Seville. Just wish I didn't have to sink $2000 more into her. I expected to put some money but not that much. :(

i hate this car!!!!! i bought this car after the honda civic i had went caput. since i bought it in september of 2008 i have replaced the alternator, the seals and gaskets the harmonic balancer all the tires the timing belt the keys ( wich cost 70 dollars a piece because of a stupid chip) and now it wont start at all!! cadillacs suck and are pieces of crap i will never buy another one again.
