Manual Movement

The Memory Mirror Module (MMM) receives inputs from the power mirror switch to move the mirrors. Only one mirror can be moved at a time, so the mirror select switch must be placed in either the LH or RH position before a mirror can be moved. Moving the mirror switch sends inputs to the MMM. When the MMM sees a valid input, it supplies battery positive voltage (B+) to the appropriate mirror motor(s).
