("air bag" light is also illuminated)
I may have located the problem.
I could get no continuity between any of the harness connections for the CC or the horn.
After removing the air bag and the steering wheel I find
a plastic ring with the roll center gears and the connections for the
horn button, cruise control and air bag.
Drilled out the rivets and took the back off.
It appears the connection for these switches from the turning steering wheel.
to the harness that descends down to under the dash is a
ribbon cable!
This is wound around the center hub of the steering wheel connection.
I was expecting the old style ring and contact like we used to have.
My ribbon cable is broken at the center connection of the hub.
Anybody ever see this? I have searched extensively and see no mention of this.
