My cruise and horn quit working at same time - from searching I've seen that it's likely the "Clock Spring" in the steering column. The clock spring is a round collar near the top of the column that has a coil/uncoil ribbon wire in it.
Nevada, was thinking that since you had something else activated in the column (washers) go out at the same time that maybe the clock spring is your problem too.
1. I can hear a click near the steering wheel when I try the horn but that's all, still maybe the "clock spring" ?
2. How hard is the clock spring to replace? (I have had some of it apart already when I replaced the cruise switches (only $40 at directfordparts.com, but that wasn't it
)
Here is a link to a diagram showing the clock spring on a 2000 F350, I think it is about $80 list.

Other info I got from searching about cruise fixes:
1. Make sure your brake and backup lights are working.
2. Make sure the little switch your emergency brake lever hits when you release the brake is getting tripped and is working. If your emergency brake light stays on the cruise won't work.
3. Check the pressure switch located on the master cylinder.
