Check the battery connection, under the rear seat.
The battery to a 1999 Cadillac Seville SLS is underneath the backseat of the car. The car manual explains how to remove the rear seat and gain access to the battery. It is much easier then it sounds.
To reset the AC compressor on a 2003 Cadillac Seville SLS, first, disconnect the negative battery cable for about 10 minutes to reset the vehicle's electronic systems. Reconnect the battery, then start the engine and turn the AC to the maximum setting. If the compressor still doesn't engage, check the fuses and relays related to the AC system, and ensure the refrigerant levels are adequate. If issues persist, further diagnosis may be required.
There may be other differences, but the one I know is the SLS has a 275 HP engine and the STS has a 300 HP engine.
