Instead of looking for a fuse specifically for the trunk release, troubleshoot these areas:
* Check the trunk release switch: Make sure the button itself is working correctly. Try the key fob release (if equipped) as well.
* Check all fuses related to power locks and body control: Don't just focus on a single, specific "trunk release" fuse. Look at the fuses related to the power door locks, central locking system, and any fuses labeled "body control" or similar terms in both the underhood fuse box and the interior fuse panel (usually located under the dashboard). These are the most likely suspects if there's an electrical problem affecting the trunk release.
* Inspect wiring: Carefully inspect the wiring harness leading to the trunk release mechanism. Look for any signs of damage, corrosion, or broken wires. This is more involved and requires some automotive knowledge.
* BCM (Body Control Module): The BCM controls many electrical functions, including the trunk release. A faulty BCM could be the cause. Diagnosing this requires specialized tools and knowledge.
Fuse Box Locations: Consult your owner's manual for the precise location and diagrams of both fuse boxes (underhood and interior).
If you've checked all fuses and wiring and the problem persists, it's best to take your Cadillac to a qualified mechanic or auto electrician. They have the tools and expertise to diagnose and repair more complex electrical issues. Attempting to troubleshoot the BCM without the proper knowledge can cause further damage.
