Power Mirror System: Description

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.
