My rearview mirror fell off and the power cord (I think that is what you would call it) broke. This seems to have created the connection for external door locks and it will not lock from the outside. Locks fine from the inside.

Hello, your wiring to the mirror may have detached along with the mirror when it came off. Any time electrical wiring becomes damaged, it can cause multiple related effects -- too hard to guess without hands not testing. For example, a fuse may have blown to protect the damaged circuit, and related components may share the same fuse. I would check fuses, but definitely the wiring and mirror must be repaired properly as well.

I'd start by fixing that rearview mirror and any broken wiring first. That may just correct the issue. Use this link to find a good shop near you. https://repairpal.com/repair-shops Alex
