When you go to get a clockspring go to Advance Auto. The dealership wanted $155.00 for one. Advance $65.00. Disconnect the battery and let it sit for 20 minutes or so, then remove the airbag all the while being below the steering wheel. Not to say the bag will deploy it's just better to be safe than sorry. If you've never done one get the correct steering wheel puller and be careful not to strip out the holes for the puller bolts. The wheel is aluminum and strips easily.
My question still stands. All three components are wired through the clockspring assembly. Diagnose all three if you want but you'll still end up with a clockspring replacement. I would never recommend ignoring the safety aspects of airbag removal but spending hours on a troubleshooting tree and still end up at square one is a waste of time. Unless you want to do it as a learning tool.
Just replaced one in a 2000 E250 Quigley conversion. Immediate repair to all the airbag light, horn and cruise control. Took maybe an hour. Go for it E. Koy.
So from one Ford nut to another, if you have a flat do you diagnose the whole drive train? C'mon, the man has an electrical problem with one area of his van which is at the business end of the steering column. The common denominator here is the clockspring or a clockspring connector under the dash that he may have gotten his big foot into. Granted, if it was ONLY a flashing airbag lamp I would do exactly as you describe. The codes and a full diagnostic would definitely be in order. But it's not. It's three items all related to one component. The clockspring is a common problem. Why turn it into a "can't see the forest for the trees" thing.
I do agree on doing a diagnostic in place of throwing parts at something but this isn't that situation.
Argue all you want but my big Christmas dinner is ready and I ain't missin' it!
The airbag is easy to remove, as long as you follow the 2-3 simple steps. After removing the airbag, just leave it on a table, undisturbed, with face up.
With these 2 tools it should take you about 7 minutes. Just disconnect the battery and have a cup of coffee for 15-20 minutes first, so that the ABS powers down (about 10 minutes).
Make sure you tighten the steering wheel back up at the proper torque.
