Which seat are you seeing this wire and which function on the seat is not working? I imagine it is one of the functions with the blue wire but which is recline or the rear vertical. Clearly if the wire is not connected properly then that would be the issue.
Let me know if you can get a picture of the wire as it sits or if you just pull on the wire it should not pull out. If it does then you are correct. These terminals have a lock on them that will hold it in the connector so it should feel firm.
If it pulls out then you will need to take the connector apart and see if you can get it to seat back in. If you cannot then I would recommend getting a connector kit. Basically that is just a new connector with wires that you can solder into the existing harness so that you don't need to replace the entire harness.
Let's start with this and go from there.
