Mirror, Outside Rearview: Operation

WARNING: This page is about a different car, the 2017 Jeep Cherokee. However, it is still accessible from the selected car via links, so may be relevant.

Each power mirror articulation mechanism is driven by two individual Direct Current (DC) reversible electric motors. Each motor also features Positive Temperature Coefficient (PTC) protection. One motor in each mirror controls horizontal (left and right) movement, while the second motor controls vertical (up and down) movement. The power mirror selector switch setting determines which mirror is to receive the output from the power mirror control switch.

The power mirror control switch determines which motor will be energized and the direction in which the motor will be driven. When battery current and ground are output from the control switch to the two motor terminals, the motor rotates in one direction. When the switch output polarity to the motor connections are reversed, the motor rotates in the opposite direction. The mirror articulation mechanism also incorporates clutches that protect the mechanism by disengaging the drive whenever the travel limits of the articulation swivel have been reached.

The power mirrors as well as the hard wired input circuits for the mirrors may be diagnosed using conventional diagnostic tools and procedures. Refer to the appropriate wiring information.
