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.
