Chevrolet Equinox Service Manual: Outside Mirror Description and Operation (Without LTZ/SLT)

Power Mirror System Components

The power mirror system consists of the following components:

Mirror direction switch — Controls the left, right, up and down movements of the mirrorsMirror select switch — Allows the operator to select the mirror to be movedLeft outside mirror — Contains both the horizontal and vertical mirror motorsRight outside mirror — Contains both the horizontal and vertical mirror motors

Each of the outside power mirrors contains 2 motors. The up-down motor operates thevertical directions and the left-right motor operates the horizontal directions. Eachof the power mirror motors are internally circuit breaker protected.

Power Mirror System Controls

The outside mirror switch incorporates a mirror select switch and a 4-position mirrordirection switch.

The mirror select switch allows the driver to select the mirror to be moved by pressingthe switch to L-position enabling the left outside mirror or pressing the switch toR-position enabling the right outside mirror.

The mirror direction switch is a 4-position switch that allows the operator to movethe selected mirror up, down, left or right.

Power Mirror System Operation

The outside mirror switch receives power through the battery positive voltage circuitfrom the underhood fuse block. The outside mirror switch also receives a constantground.

The 4-positions of the direction switch have multiple switch contacts. When not inuse, the directional contacts are isolated from any circuit. Each of the contactsare connected to opposing sides of the appropriate mirror motors through the selectorswitch. The selector switch interrupts or completes these circuits depending on theposition of the selector switch, L or R.

If the mirror select switch is placed in the L-position and the up switch is pressed,battery voltage will be supplied to the driver outside mirror vertical motor throughthe driver mirror motor up control circuit and return to the mirror switch throughthe driver mirror motor left/down control circuit, then to ground and the mirror willmove up. If the down switch is pressed, the driver mirror motor left/down controlcircuit suppliesbattery voltage and the driver mirror motor up control circuit completes the pathto the mirror switch, then to ground and the mirror will move down.

The remainder of the mirror functions operate in the same manner as described above.Placing the mirror control switch in opposing positions, left/right or up/down, willreverse the voltage polarity to the mirror motor, utilizing the same circuits andthe mirror will move accordingly.
