GMC Power Mirror Switch

The switch is the cabin control; the motor that moves the glass or folds the mirror is part of the mirror mechanism. A switch listing does not automatically include the mirror assembly or its motor.

The folding function requires compatible mirror and vehicle equipment as well as the appropriate control. One A-Premium switch is specifically listed for models without a power-folding switch.

Some vehicles use a selector marked L and R with a shared adjustment control. The switch must be designed for the vehicle's original control arrangement and equipment.

Their connections differ and must match the vehicle circuit. Current A-Premium examples include both counts; terminal count by itself also does not establish that two eight-terminal designs fit the same application.

Ice or dirt at the pivot can add resistance, and a power or control-circuit fault can also stop operation. Inspect the mirror and electrical system before replacing a switch.
