You can Select Your Vehicle to check if 4L3Z-17700-A fits your vehicle.

To remove the exterior mirror on 2012, and before models, you will need to remove the door-slightly, then the front door mirror cover, if there is a speaker electrical connector it will be disconnected, then disconnect the electrical connector of the mirror. After that, the mirror mounting nuts should be unscrewed, and the mirror ought to be pulled out; the reverse is the process of installation. For years 2013 and onwards the process starts by removing the door trim panel followed by the removal of the bolts that fixes the door module in position and then it is removed. Here, strip the water shield from the mirror attachment nuts then the lower water shield and door speaker. Third, the front window regulator track bolt at the 1 o'clock position then put the window regulator track aside. To remove-raise the speaker grille and lower water shield to get access to the mirror electrical connections, then, unscrew the nuts twisting the exterior mirror electrical connection and then unscrew the nuts that secure the exterior mirror; to install-reverse the procedure. The interior mirror types available are six. For Type 1, remove the electrical connection and then use special services tool 501-190 to loosen the mirror mounting clip, place the tool were the clip normally grips and with a gentle hit on the tool it pops of the mirror, to replace the mirror slide it into place and ensure the clip locks into place. For Type 2, then, remove the electrical connection, then using the tool 501-D118A to release the mounting clip on this mount, slightly pull the lower edge of the mount away from the windshield then pull the mirror off, to install it just reverse the process. To perform Type 3, first, the upper and lower rain sensor cover needs to be unbolted, and the electrical connectors have to be disconnected; the mirror has to be angled in a manner that brings the index tab above the mounting base retainer, the mirror rotated 45-degrees in a counter clockwise direction and removed; to replace it, all these steps must be followed in reverse. For Type 4, you need to unscrew the rain sensor panel, disconnect this panel electrically, unscrew the mirror and rotate it clockwise, and then remove the mirror, important here is that a new mirror will require to be programmed using a scan tool. For Type 5, you have to unscrew the screw by using a small flat bladed screwdriver to unlock the tab, and slide of the mirror from the base and put it back in place in the same way. For the Type 6, the electrical connector should be disconnected and then the set screw located at the bottom of the mirror needs to be loosened to release the Mirror from the mount and to be slid upwards, while to assemble it has to be slid downwards until the screw is tightened.

Most 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 that sends voltage to the left or right side mirror. With the ignition ON but 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 a problem with the drive mechanism inside the mirror. If the mirrors do not operate and no sound comes from the mirror motors, check the fuse. If the fuse is OK, remove the mirror control switch and have the switch continuity checked by a dealership service department or other qualified automobile repair facility. Test 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 no voltage in each switch position, check the circuit between the mirror and control switch for opens and shorts. If there's voltage, remove the mirror and test it off the vehicle with jumper wires, replacing the mirror if it fails this test.

Disengage the sail panel clips and remove the panel by prying it out. Disconnect the electrical connectors from the mirror and sail panel, if equipped. Remove the mirror mounting fasteners and take out the mirror. Installation is the reverse of removal.

Disengage the sail panel clips and remove the panel by prying it out. For 2015 and later models, the door panel must be removed to access the electrical connectors. Disconnect the electrical connector from the mirror, which includes the mirror electrical connector and the mirror mounting nuts. Remove the mirror mounting nuts and take out the mirror. Installation is the reverse of removal.

Unscrew the mirror mounting bolt, then withdraw the mirror from the outside of the door, ensuring to recover the mirror seal as the wiring/cable is drawn through the rubber grommet.

Troubleshooting the SJB or BCM can be performed accurately and simply, but only with a professional-grade scan tool.

Installation is the reverse of removal.

Lower the window for access to the mirror mounting nuts.

The first step is to detach the side view mirror trim cover by pulling straight out. If equipped, disconnect the electrical connector.

The electric rear view mirrors use two motors to move the glass; one for up and down adjustments and one for left-right adjustments.

Disconnect the electrical connector for the power mirror (if equipped).

Remove the mirror and test it off the vehicle with jumper wires. Replace the mirror if it fails this test.

Remove the door trim panel and the plastic watershield.

Detach the control lever from the instrument panel or door and connect a string or thin wire to the end of the control cable, then detach any retaining clips.

Listen carefully for the sound of the electric motors running in the mirrors.

Only if it is equipped.

If there's voltage, remove the mirror and test it off the vehicle with jumper wires.

Detach the control lever from the instrument panel or door and connect a string or thin wire to the end of the control cable, then detach any retaining clips.

Disconnect the auto-dimmer electrical connector.

Listen carefully for the sound of the electric motors running in the mirrors.

The control switch usually has a selector portion that sends voltage to either the left or right side mirror.

Peel back the insulator pad, then remove the three mirror retaining nuts and detach the mirror from the vehicle.

Disconnect the switch and check it for continuity in all its operating positions. If the switch does not have continuity, replace it.

Remove the mirror retaining nuts and detach the mirror from the vehicle.

If the motors can't be heard or if the mirror glass doesn't move, there is probably a problem with the drive mechanism inside the mirror. You should remove and disassemble the mirror to locate the problem.

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.
