2003 Cadillac Seville Problems
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.
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.

2003 Cadillac Seville Reviews
bought my 03 sls used with 100K and no engine leaks at all. Beautiful car with all options. Only Problem is a leaking transaxle seal on the drivers side, that really dumps it out when in reverse. Love this car has more power than you'll ever need. So I'm going to pay the 1,400 to fix the seal. To me it'll be worth it.
