Drivers window doesnt work, regulator good, power to up motor terminal no power to down motor terminal, window goes down when buzzed with external source. Buzzed up terminal but motor did not work. Brown wire is down and blue wire is up.

Sometimes on these creatures it's not he power but the grounds. This system "toggles power" to either side of the motor the other is constant ground thru the switch to a bolt actually under the drivers carpet/ seat. Your switch also has the express down feature? This item is a litle MODULE built inside the switch. If it fails replace switch since both wires to the motor pass thru the module. Either way from the sound of it you used a power probe to test? Try again but disconnect the motor completely and power and ground direct just switch wires to go other way. If motor works fine both direction replace driver side switch.
