A visual inspection of things electrical will not necessarily disclose a fault. A proper continuity test is essential.

Unless you gleened more information than the rest of us i.e. the actual fault code then you don't know. He either saw the fault code himself, or was told the fault code by the mechanic who was unable to fix his car. We didn't see what the fault code was. It is no offense to him, but it is why I was asking for more details. IMO not enough information. Besides those checks weren't the end all be all... they were called a good place to start.
