A-Premium Driver Side Heated Mirror Glass for Chevrolet GMC Cadillac — Left Front, Power-Adjustable with Turn Signal (2003–2007)

A-Premium's driver-side heated mirror glass replaces the original left-front mirror on select Chevrolet, GMC and Cadillac trucks and SUVs, restoring power adjustment, heating and integrated turn-signal functionality.

If your left exterior mirror glass is cracked, fogged, or missing its heating element or turn signal, this direct-fit A-Premium replacement gives you the same flat, power-adjustable mirror surface used on many GM full-size models from 2003–2007. It’s manufactured to match OE dimensions and electrical features so installation is straightforward when your vehicle has the matching backing plate and connector.
