On these models, the outside mirrors are controlled by the Front Door Power Switch Assembly (FDPSA), which houses the mirror control switches and the Front Door Control Module (FDCM). The FDPSA interprets the mirror control switch movements, while the FDCM supplies the battery voltage and ground to the motors to move the mirrors. The electric rear view mirrors use two motors to move the glass; one for up and down adjustments and one for left-right adjustments. The control switch has a selector portion which sends voltage to the left or right side mirror. With the ignition in the ACC position and the engine OFF, roll down the windows and operate the mirror control switch through all functions (left-right and up-down) for both the left and right side mirrors. Listen carefully for the sound of the electric motors running in the mirrors. If the motors can be heard but the mirror glass doesn't move, there's probably a problem with the drive mechanism inside the mirror. A loud but distinct clicking can be heard with most failures associated with the drive motors failing to move the actual mirrors. Power mirrors have no user-serviceable parts inside - a defective mirror must be replaced as a unit. If the mirrors don't operate and no sound comes from the mirrors, check the
Fuses. If the fuses are OK, remove the mirror control switch. Have the switch continuity checked by a dealer service department or other qualified shop. Check the ground connections. If the mirror still doesn't work, remove the mirror and check the wires at the mirror for voltage. If there's not voltage in each switch position, check the mirror and control switch for a disconnected (open) lead. It should be noted that a weak or loose connection is often overlooked as the problem. Be sure to check all electrical connections as well. If there is voltage and grounds at the leads on their respective positions and the mirror still does not respond, replace the mirror assembly.
