120 Rear Offside (UK) Door Stopped Locking/Unlocking Via Central Locking This Morning

[tlaw259]

I've searched forums but not found anything yet that matches my issue!

Door no longer unlocks or locks.
But! It unlocks and locks via the internal manual door lock//unlock catch.

Purely the central locking not activating on the rear offside door.
All other doors and tailgate work fine.


Anyone had this same issue? i.e. 1 door not responding to central locking?
And hopefully! What was the cause?

Many thanks.

UPDATE - Just tried the central locking again.
After sun had melted frost from door.......and central locking now works on rear offside door.

Only when hard frost on the rear offside door is it NOT working......
For clarity, not working as in not even trying to trigger a lock or unlock....no lock noise, like there is on other doors.


Wiring?
