Rear View Mirror (Without One-Touch Up): Other Ford Escape III

Power Mirrors

The LH and RH exterior mirror glass movement is controlled by the exterior mirror control switch and the LH and RH exterior mirror motors. When the ignition is ON and the exterior mirror control switch is pressed in the up, down, left or right direction, voltage and ground is supplied to the appropriate exterior mirror motor.

Exterior Mirror Control Switch

The exterior mirror control switch is a momentary contact switch that is integral to the master window control switch. The exterior mirror control switch also uses a rocker-type selection switch to allow the driver to determine which exterior mirror will be adjusted.

Exterior Mirror

Each exterior mirror has 2 bi-directional motors that are used to control the up, down, left and right movement of the exterior mirror glass. The exterior mirror uses a jumper harness between the vehicle wiring harness and the exterior mirror motors. This jumper harness is integral to the exterior mirror.

Interior Rear View Mirror - Manual-Dimming

The manual dimming interior rear view mirror has a lever at the bottom of the mirror that must be pushed forward or pulled rearward to change the reflectance level of the mirror glass.

Interior Rear View Mirror - Auto-Dimming

Voltage is supplied to the interior auto-dimming mirror when the ignition is in ACC or ON. When the forward facing sensor detects daytime conditions, the rearward facing sensor is inactive and the mirror stays in a high reflectance mode. When the forward facing sensor detects nighttime conditions, the rearward facing sensor is active and is used to detect glare from the headlamps of vehicles approaching from the rear, or other glare producing light sources. To provide increased visibility when backing up, the interior auto-dimming mirror returns to a high reflectance mode whenever the vehicle is in reverse.

The auto-dimming interior mirror utilizes 2 photoelectric sensors, one on the front of the mirror (facing the windshield) and one on the rear of the mirror (in the mirror glass). Based on input from these sensors the auto-dimming feature adjusts the reflectance level of the mirror glass to eliminate unwanted glare. The reflectance level of the mirror glass is variable and adjusts based on the amount of glare detected by the rearward sensor in relation to the ambient light conditions detected by the forward sensor.
