Instead of trying to find a fuse to remove, which is unsafe and could lead to further damage, consider these options:
* Disconnect the motor directly: This is the safest approach. Locate the electric seatbelt motor (it's likely under the seat or near the seatbelt retractor). You can disconnect the electrical connector leading to the motor. This will stop the motor from running but will also disable the automatic seatbelt feature. You'll need to manually retract and fasten your seatbelts.
* Check the seatbelt switch: There might be a switch related to the seatbelt system that's malfunctioning and causing the motor to run continuously. Inspect the switches or controls related to seatbelts. Sometimes a simple cleaning or adjustment might solve the problem.
* Inspect the wiring harness: A short circuit in the wiring harness could also be causing the problem. Carefully inspect the wiring to the motor for any damage or exposed wires.
WARNING: Working with car electrical systems can be dangerous. If you're not comfortable working with car electrical systems, it's best to take your car to a qualified mechanic. Continuing to run the motor continuously will drain your battery and could potentially damage the motor itself.
