Here is a quick DIY on socket replacement.

First remove the plastic clip with a small bladed screwdriver.


Next pry out the rubber seals from rear of socket.

Next insert a small flat bladed screwdriver in from the rear to depress the tang that secures the terminal in place

Once this is done you can push the connector forward through the socket.

There are two ears that will need to be bent inwards to allow the terminal to be pulled out of the socket

Once you have both wires out of socket you can then insert the terminals in through a replacement socket.

You will need to bend the ears back straight and make sure the little tang that secures the terminal is bent out also
You can then pull the terminal back into socket to secure it in place. Remembering to replace the rubber grommets will see you finished.
