Hi

Wondering if anyone can point me in the right direction for this, the RHR door actuator doesn't lock, but the rest of its functions seem to work; unlocks the other doors when you open it, lights come on..

Buttt it won't lock, no noises, nothing. It first happened after I washed the car (or I noticed it at least) a while ago, then started working again, but now it's been dead for quite a while.. All other doors lock except this one.

Is there any hidden fuses or relays to check ? Or would this be a faulty BEM ?

It is a BA 2004, but it's been garaged all its life and is basically like new, so I was thinking it was somewhat unlikely for a rust hole and water logged cables or something similar... ?

check wiring at B pillar plug for water and or corrosion -
replace actuator

I forgot to mention I did already change the actuator, and it still didn't work after this. Now today I go to double check the wiring in the B pillar (which is bone dry, looks brand new) the door lock is working again...
Anything else that could be the culprit ?

If left doors are working then not BEM module as they are on the same circuit - then you have a fault in wiring or faulty actuator
