What should I do if my outside faucet is frozen
No water is coming out and it's 18 degrees outside.
If you have a faucet outside that is frozen and you really need it to start running, you will want to try and melt the ice. You will need to warm it up with a heater or blow dryer. You will also need to insulate the pipes.
A hair dryer will probably work just fine, however this spring or summer, install "frost free" hose bibbs on all of them. They are a bit more expensive, but you will never have this problem again.
Use the inside faucet
