Just last week the real left door locking system has stop working using the remote key or any key. A few days before that, from time to time the locking system on that door stopped working but now, doesn't work at all. The rest of the doors are still working but the locking system on the rear left door has stop working, even if a push de lock button on the drivers door. Now I have to lock the door manually. I've checked all the wires on that door and on the pillar but they are all fine. Also I have a problem with all my interior lights, the all stop working. It is possible to be a connection between these to problem? Thanks
