1) Disconnect the ground cable from battery.
CAUTION:
Disconnect the ground cable from the battery with the driver's and the passenger's doors open (with
the glass lowered to a position where the door can be opened/closed with no problems). This is to
prevent molding damage that occurs when opening/closing a door with the glass fully closed and the
ground cable disconnected due to the power window index function that slightly opens/closes the
glass in conjunction with opening/closing doors.

clip that holds the harness.
