1. Did you check the fuse for the horn ?
This is Engine Compartment Fuse # 7 ; 20A

2. You can pull the Horn relay and jumper the normally open contacts ( as shown with the red line below ) to activate the horns without using the button.

If this does not work, either the fuse is no good, or the ground at the horn connector is no good. Replace the fuse or test the ground on the horn connector with a meter ( set to ohms ) to the battery neg terminal.

If this does work, using a meter ( set to ohms ) test from pin #2 in the relay socket ( as shown above ) to the battery neg terminal. When you press on the horn button, you should have a low resistance ( The test steps will stop you from paying for basic trouble shooting issues.

2007 ford expedition driver side window wont work

If the 2007 Expedition is the same as the F-150 ( not 100% sure it is ), the main switch is most likely the cause. My 2006 F-150 switch went out at ~ 30K miles, the contacts were blackened to the point the carbon acted like an insulator.
You can take the switch apart and clean them with a typewriter eraser or light emery cloth.

In this picture you can see how back the contacts look from use :

The F-150 new driver's side switch is ~ 65.00 + S/H online ( Tasca Ford ), and an easy swap. You can work on cleaning the contacts on the old one when you install the new one, if you want to go that route.
