power door locks

I have a F150 and all my door locks stopped working all at the same time. I hear clicking in the dash and in the door when I press the lock and unlock. but my locks dont work. I have to open by hand and with out the locks working, my alarm does not work. Does anyone know how to fix it

what year?
later model fords have breakers and fuses under the hood as well as by your left knee.
check the owner's manual.

John, It maybe that the electric breaker has weakened and can no longer flow the current need to operate the door luck and that is why you hear a clicking in the doors and dash.
See if this website can help you lock towards the bottom where the cassis diagrams are.
