A method for assembling a mirror reflective element sub-assembly for a vehicular exterior rearview mirror assembly includes assembling an indicator module by heat staking a printed circuit board at a receiving part of a housing to form a housing and printed circuit board assembly and dispensing potting material at the printed circuit board to seal the printed circuit board at the housing and aligning and taping a diffuser at the housing. A back plate is provided that has an indicator attaching portion for attaching the indicator module. The back plate is placed at a support fixture and a mirror reflective element is attached at the back plate. The indicator module is attached at the indicator attaching portion of the back plate. Light emitted by the indicator module, when electrically powered to emit light, passes through the mirror reflective element at an aperture of the back plate.

Method of assembling mirror reflective element sub-assembly for exterior rearview mirror assembly

A method for assembling a mirror reflective element sub-assembly for a vehicular exterior rearview mirror assembly includes providing a support fixture having locator pins disposed at apertures thereof and protruding therefrom. The locator pins are received through corresponding apertures of a heater pad and through corresponding apertures of a back plate to align the back plate at the heater pad at the support fixture. A mirror reflective element is attached at the back plate and heater pad construction, and that construction is disposed at a laser ablation fixture, whereby the locator pins of the laser ablation fixture are received through the apertures of the back plate to align the construction at the laser ablation fixture. After an indicator icon is laser ablated through the mirror reflector, the construction is removed from the laser ablation fixture, and an indicator module is snap attached at a receiving portion of the back plate.
