Cadillac Seville STS Problems

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.

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 anti-lock brake system (ABS) control module may fail causing the ABS light to illuminate. Failed modules should be replaced to restore ABS operation.

Cadillac Seville STS Questions

My 2003 Seville STS, VIN 9, needs new transmission. Can I replace it with one from 2003 SLS or DeVille? Will one from cars model year 200-2002 work? If not, can I swap transmission AND computer wit SLS model? I don't care about loosing some performance, I just need to repair it for less.

I changed the trans fluid pressure switch but still have the same problem.

The car is actually a 1991 Cadillac Allante, where is the Controller for the ABS system located and how hard is it to replace?
