OK kids i have an update!
i ordered the part from sewell lexus and had them fedex 2 day it for $190
i decided to give it another dry run since the part has not been delivered yet. i took the door panel off, removed the 3 torx screws from the lock assembly, disconnected all the electronics+lock and handle wires from the door, removed the panel, and loosened the 2 10mm screws that hold the track for the window. with the track loose i wiggled the lock assembly out. i disassembled the lock assembly and found that the contacts for the little motor that locks and unlocks the door were crusted up and filthy
i cleaned them, reassmbled the lock assembly and put the door back together and it works! i guess i have to decline the delivery when it gets here.
i just saved myself $190 for the part. my dealership wanted $240 for the part and @$250 for the install.
