LH Mirror

WARNING: This page is about a different car, the 2002 Oldsmobile Aurora and 2001 Oldsmobile Aurora. However, it is still accessible from the selected car via links, so may be relevant.

For a LH mirror left movement, the driver door module (DDM) supplies battery positive voltage (B+) via the left mirror motor left circuit, and ground via the left mirror motor right circuit to the LH mirror horizontal motor. For a LH mirror right movement, the DDM reverses the polarity and supplies battery positive voltage (B+) via the left mirror motor right circuit, and ground via the left mirror motor left circuit to the LH mirror horizontal motor. For a LH mirror up movement, the DDM supplies battery positive voltage (B+) via the left mirror motor up circuit, and ground via the left mirror motor down circuit to the LH mirror vertical motor. For a LH mirror down movement, the DDM reverses the polarity and supplies battery positive voltage (B+) via the left mirror motor down circuit, and ground via the left mirror motor up circuit to the LH mirror vertical motor.
