Isuzu Repair: 99 amigo lug nuts, lug bolts, lug nuts

Question
I purchased a 99 amigo about 1 month ago.  I took the vehicle to get inspected and it did not pass.  The screws where the lug nuts go on the tires are completely removed 2 on one tire and one on another tire.  How do I fix this? Also where is the fuse for the horn? Thank you

Answer
Well the Tire and wheel will need to be removed as well as the actual axle/spindle to replace the lug bolts. I am sorry for the delay Joyce and any other questions will be happily answered. The horn fuse is located on the driver-side dahsboard on the left side of the steering wheel in between the door and the dashboard if that makes any sense.
