My horn hasn't worked in my 95' F150 since I purchased the truck.
Any common problem why it wouldn't work?
Just trying to save me some time.
Thanks in advance!

Airbag clockspring most likely.

If you have no horn, no cruise control, and a flashing airbag light, your clockspring is out.

This, sometimes the light burns out because people let it go too long, but yeah if your cruise doesn't work either than it's your clock spring.

Simple fix, unplug battery for a couple minutes, leave door open or lights switch on to pull any power out of the system, unscrew air bag bolts on back of steering wheel, pull airbag out and disconnect the connector, use steering wheel puller to remove the steering wheel, replace the clock spring, be mindful of not letting the new one spin before you install it as there are ribbon wires in there that will break if it goes too far in either direction, repeat process in reverse to install.

NOTE:
Do not reconnect the battery until clock spring is plugged back in, I made this mistake as I was installing a new stereo and wanted to test it. There is a safety ground tab in the air bag connector that will fry a thermal fuse in the Airbag Diagnostic Module if power is present without the plugs connected. It's a simple fix as well, and cheap, but there are only a few places that sell the thermal fuse in the US and shipping takes a week or more.
