A-Premium Driver Side Heated Mirror Glass for Chevrolet GMC 2003–2007 — Flat Powered Glass with Turn Signal

A-Premium Driver Side Heated Mirror Glass replaces the OEM left front mirror with a powered, heated, turn-signal-equipped glass that fits many Chevrolet, GMC and Cadillac trucks and SUVs from 2003–2007.

If your original driver-side mirror glass is cracked, fogged, or missing its heating function, this A-Premium unit is built to match factory fit and features for a straightforward swap. It’s a flat glass with a backing plate and integrated heating to clear ice or condensation, plus a built-in turn signal for visibility. The part is designed for power-adjust models and excludes blind-spot and auto-dimming options, so it’s ideal for vehicles with the corresponding factory features.

Which vehicles will this driver-side mirror glass fit?

This mirror is manufactured to fit a long list of Chevrolet, GMC and Cadillac models from the 2003–2007 era. Confirm fit by matching your vehicle’s year, model, and driver-side left-front position before ordering.

• Chevrolet: Avalanche, Silverado (1500/2500/3500 series), Suburban, Tahoe (2003–2007 specific years)
• GMC: Sierra (1500/2500/3500), Yukon and Yukon XL (2003–2007 specific years)
• Cadillac: Escalade variants (2003–2006) and Escalade EXT/ESV where applicable

How does this mirror compare to the original factory part?

The A-Premium glass is produced to match OEM dimensions and functions for a like-for-like replacement without extra wiring or frame modifications. It includes the heated element and turn-signal lens like many factory-equipped mirrors, but does not add blind-spot detection or auto-dimming features if your OEM mirror didn’t include them.

• Reference numbers: 56318, 88944391, A2GM102L and related GM codes for cross-checking
• Flat glass profile and powered adjustment—mirrors angle with your existing motor
• Includes backing plate for secure, straightforward installation

What are the electrical and physical specifications I need to know?

This unit is built for powered mirror systems and includes an integrated heating grid and a turn-signal light. It does not include an auto-dimming cable, spotter glass, or blind-spot sensor, so it pairs only with vehicles that originally had simple power mirrors plus heating and signal functions.

• Position: Front left (driver side)
• Glass Type: Flat; Mirror Adjustment: Power
• Features: Heated element, backing plate, integrated turn signal; excludes blind-spot and auto-dimming

A-Premium backs this part with a one-year unlimited-mileage guarantee for manufacturing and material defects. That warranty and the clear fitment list make it easy to replace a damaged mirror glass without the expense of a full mirror head assembly.

Who is this for? Owners of compatible Chevrolet, GMC or Cadillac trucks and SUVs (2003–2007) who need a direct-fit driver-side replacement glass with heating and turn-signal function. It’s aimed at DIY installers and repair shops that require an accurate, OEM-style glass replacement without added features like blind-spot or auto-dimming systems.
