2004 Lincoln LS 3.0 will drain the battery overnite. Found open circuit at fuse #20 passenger compartment fuse panel. It is labeled FEM DATC Cluster REM.
Two issues, the battery drain and the door unlock. You must determine what is causing the drain. Check wiring, inspect for shorts, ensure proper connections. Otherwise, consult a professional mechanic or auto electrician.
As to the issue with remote locking/unlocking could be related to the Remote Entry Module (REM).
The REM controls several features, including door locks, windows, lights, and more.
Since the doors lock automatically while driving, it indicates that the central locking system is partially functional.
However, the lack of response to the remote suggests a problem with the REM or its associated components.
Consider checking the REM's connections, fuses, and wiring. These electrical problems are complex. You may have to rely on a professional to sort out the diagnosis. An auto electrician can check the communication between the REM an the actuator and other components.
