1994 E-150 airbag light blinks twice and then blinks 5 times whats this mean and what needs to be fixed?

Hello,I am living in Europe the Netherlands and my wife drives a '94 e150 hightop conversion van. We had a similar airbag lamp problem. we also had (not always) a problem with engaging the cruise control on the steering wheel. After a year the horn did not work.For us this was the signal that the spring coil in the steering wheel was not working. The spring coiul is a need design that connects the electrical things on the steering wheel (horn, airb, cruise) to the fixed steering colomn/chassis.A springcoil costs about USD 90,=Regards,Jan Valk
