Description & Operation

WARNING: Vehicles are equipped with air bag supplemental restraint system. Before attempting any repairs involving steering column, instrument panel or related components, see SERVICE PRECAUTIONS and DISABLING & ACTIVATING AIR BAG SYSTEM in appropriate AIR BAG RESTRAINT SYSTEMS article.

One mirror control switch adjusts both left (driver's side) and right (passenger's side) mirrors. Left side of mirror switch is for driver's side mirror and right side of mirror switch is for passenger's side mirror. Use control pad below mirror switch to adjust mirror. Heated and memory mirrors are available as an option.

Each power mirror assembly contains 2 reversible motors: an up/down motor and a left/right motor. Mirror control switch reverses polarity of motor circuit to change direction of mirror movement. Each motor contains a self-resetting circuit breaker, which opens when mirror reaches its mechanical limit of travel. On vehicles with memory seat/mirror systems, each power mirror assembly contains potentiometers that are used to determine mirror position.

Rearview mirror contains two reversible DC motors and two position sensors. One motor adjusts mirror to UP/DOWN or vertical position. Another motor adjusts mirror to LEFT/RIGHT or horizontal position. Memory Seat Module (MSM) controls mirror direction by changing polarity of voltage applied to motors. This monitors signal circuits of position sensors to determine position of mirror. When a memory function is requested, MSM stores position of mirror into memory.
