B2141 GMC Description
Outside rearview mirror switch supplies inputs to Memory Mirror Module (MMM) to drive outside rearview mirrors horizontal and vertical motors. Outside rearview mirror switch must be in either L or R position in order to operate outside rearview mirror. When outside rearview mirror switch is actuated, the battery voltage input signal and the ground input signal is sent to MMM. When MMM recognizes input combination, it moves the appropriate mirror to the requested direction. If MMM does not recognize input combination as a valid input, it ignores combination and does not move outside rearview mirror.
