What is the cost to fix non-working horn.

There are two horns in the front grill area get someone to press the horn switch and check for power at the horns if there is power then the horns are bad probably, .6 hour labor to replace the horns and $50 for the horns, if there is no power at the horns when the button is pressed the fuse needs to be checked and the circuit traced to see where the fault is.
