Khai likes to do his own repairs but he's not confident about his diagnoses. Is it fair for him to ask a shop to make a diagnose but then use that information to do his own work? Tom and Ray weigh in on this mechanical, ethical dilemma.
Prosecuting attorney Kat needs Tom and Ray's help to solve a crime! Some thieves messed with the dome light in an elderly woman's car so that it wouldn't turn off. While one of them was "helping" her fix the light, the accomplices sneaked into her house and ransacked the place. Can Tom and Ray figure out what they did to the dome light and help Kat get the bad guys?
