Central locking gremlin. New control module?

[quikveedb2]

A couple days ago my central locking started acting up; upon locking the car from either door, or the trunk the doors will unlock immediately after locking with no action from the key. If I lock from the trunk, it will stay locked, but the doors will still unlock themselves. I'm thinking it's new control module, or maybe something else, hell idk, it was working fine until it sat for 2 days. Thoughts? Tia.

Thanks guys, can you point me towards a source for the pins for the c404 connector? I definitely have some corrosion going on in there & I suspect it might be the source of my central locking problems & flickering dome lights.

I had a similar issue. For me it was the trunk actuator. Replaced it and it worked fine, so I would suggest checking those out.
