Hey,
The Aerial on my EF Falcon Does not automatically go up?
what should i do?
should i change to a manual, pull up yourself one?

i would first check fuses then maybe grab a test light adn check to see if u are getting power to the motor itself. May just require something simple or could be something like a motor ie stripped gears or broken mast cable.
If you are not sure how to make these checks drop into a ford dealer or your local mechanic adn get them to check out whats going on. Its a reasonably inexpensive common fault with the falcs (when i say inexpensive i mean under 500) so see how you go with it
