Along with your other light problem you should get the wiring manual. That way it is easier for all of us to troubleshoot. They are available on ebay for around $20. Get the original Ford book.
My reply to your other post I asked about a test light, you'll need that or a dvm for this also. Your problem is basic, the "hard" part is finding the location of the cause.

I had this recall done they put a wiring harness infront of the brake master , now I tried too use the cruise and it has failed I took the black tape off the inline fuse holder( two inline fuses) and found it corroded i'm going to bypass the ford fix to see if the fix was the problem

edit. the fuses are good

was that recall for the 99 suv expedition as well do i just call the number with the vin to find out

For your horn, check in the battery junction box for the horn relay. Jump #3 to #5, this will supply power directly to the horns. If they sound your problem lies on the switch side of the relay (horn contacts, connectors etc).

 

[stamp11127]

For the cruise there are 4 fuses to check with the volt meter. Leave the fuses plugged in. Check for voltage (12v) on both sides of the fuses, black lead to ground.

Fuse 7,20A, battery junction box - horn relay - yep it is wired into the system

Fuse 13, 20A, central junction box - brake pedal switches

Fuse 15, 5A, central junction box - brake pedal switch/GEM input

Fuse 19, 15A, central junction box - ignition power to speed control servo

First 3 are hot at all times, #4 is hot in run position
