'98 Cadillac Seville STS has a problem with the trunk opening while driving. The spring on the latch seems to be loose, so do see if a local junkyard has this latch (but fearing another loose latch) is there a parts website or parts store that may carry this latch?

There is really no such thing as a "loose latch". If they lock at all, then it is locked solid unless released. The car uses an electric release and an electric motor that pulls the lid down that could be malfunctioning.

Your right but it's still a very complex circuit for the release.
When the rear compartment lid release switch is pressed, ground is applied on CKT 1447 (PNK/WHT) at terminal D6 connector 1 of the instrument panel integration module (1 PM). If the powertrain control module (PCM) is sending a message the 1PM will send a message via the class 2 data line to the rear interface module (RIM). The RIM applies ground to CKT 1344 (LT BLU), with the valet switch in the ACCESS position, voltage is applied from the ALDL fuse 4, through the TRK REL relay coil. The relay energizes, the contacts close and voltage is applied from the BODY fuse to the rear compartment lid release solenoid. The solenoid is connected to ground G402 via CKT 850 (BLK).
