Central Door Lock
The Bentley manual has very good detail of wiring, used it to identify bad module. There are threads on the mechanical arm that breaks, causing 1 door not to lock, it could be both doors have similar issue.
Since the module was bad, i rewired mine with 2 relays to allow key lock/unlock, then attached key-less entry to complete. Since I am removing center console, removed the push button as well but sure i could wire it back in if needed.
I can scan in my modified drawing tomorrow if needed but check the door hardware first. Modules are anywhere from $80-$300.
