Tell your mechanic, main voltage at the master switch is brown wire. Black is ground, check both. If you have good voltage and ground at the master switch and no window action, I suspect the master switch. Voltage to the master switch goes hot with the key on, wired through the power window circuit breaker. The wiring harness to the driver door, door open, hinge side, probably has a rubber boot protector, if you can't access the wires another way, by pulling back on the rubber boot, you should be able to access wiring colors I mentioned, for testing.
