Dishonest shops often double-dip labor when billing multiple Op Codes. For example, if parts must be removed to access Horn Replacement, they shouldn't bill full Book Time for both codes.
Replacing the horn when the issue might be a relay or fuse (electrical diagnosis needed - an upsell risk if they didn’t check and just swap horn); upselling a “high performance” dual horn kit for louder sound at a markup; in some cases, if one horn of a twin-horn setup fails, they might replace both and charge double.
