Door locking mechanism and mechanical window mechanism not working properly

Hi,

I have 3 issues with the vehicle listed above.

1. The passenger front door will not unlock. The central locking mechanism engaged when the car rached 15 MPH and now I cannot unlock, manually or with the key fob or the unlock button in the car. Hence I cannot open the door at all, the lock button does not move. Is there an a relay circuit or fuse that if I can pull or disengage that will enable this lock to open? If so where do I find it.
2. The rear passenger door does not lock when the key fob remote is pressed. That is not as bad as the above more annoying than anything. Could this be the actuator
3. The same rear passenger door window does not go down, any ideas on this one?

The door locks are the biggest issue, I think the actuators are going in general when I do lock the car it makes a very odd noise not the normal single horn blast. Drivers door and both rear doors unlock ok on the key fob or the button in side and the trunk locks and unlocks without issue

Sorry this is a long list I know. I wonder if you have any ideas and if you can help point me in the right direction? I am more than comfortable in handling the repair myself.

Thank you so much,
Steve France
