Hello, my name is***** you are talking about the 15 amp fuse in location 20 that would mean the red/black wire that goes from fuse to airbag module has shorted to ground. You will need to follow wire to find short or run a new wire. Here is a wire diagram to help with testing, let me know if you have more questions or if there is anything else I can do to help. Thanks.

that is the fuse. I disconnected the battery and pulled the connector of the air bag controller and then connected the battery and started the car, the fuse did not blow.
guess that means that I don't have a short in the wire harness, that's good, but it looks like the controller is bad.
I had sent it into a place that repairs them, guess they did not do a good job.
Is there anything else that I can try.
I did see on some models that fuse also supplies power to the 'seat weight' controller, but I guess if the air bag controller is unplugged that that can't be it.
thanks,
David

If fuse stops blowing with controller unplugged that would mean controller is the problem. At that point I'd buy a used/new controller and tell place that rebuilt it you want money back. Let me know if you have more questions, thanks.
