I just bought the truck listed above and have no use of any controls on the steering wheel as well as no use of the horn. The airbag light, however, is not on. Does that mean I have a faulty clock spring or should I look somewhere else for the problem?
Do you

Hello,

It does sound like a faulty clock springs. Only strange part is that usually bad clock spring will trigger the airbag light.

Here are couple of articles you might find helpful:

Hello,

There is a good chance that is the case but if you want to be sure I have attached some diagrams for you. First check the number 7 20 amp horn fuse in the fuse block. If that is good move on to checking for a ground coming from horn when it is pushed. I have attached the connector view and when you test it try and leave connector plugged in and back probe from where the wire enters the back of the connector. Remove the steering column covers to expose this connector. Back probe using t-pin or safety pin and check for a ground when pressing the horn make sure your positive test lead on your multimeter is hooked to a battery source to get accurate reading. If there is no ground present I would move on the removing the horn and checking for good ground contact there and if looks okay then I would say it is possibly the clock spring.
Let me know if you need further help.
