Will this mirror glass fit my 2003–2006 GM truck or SUV?

Compatibility is built around the OE spec for left-side mirrors that use part number 88944391. This replacement is intended for a range of GM models from 2003 to 2006, but confirm fit by checking your original part number and the mirror shape in the product images before ordering.

How easy is installation and what wiring is included?

Installation is intended to be user-friendly: the mirror glass snaps into the factory housing and the included 4-pin adapter wire handles power for the heating element and turn-signal connection where applicable. No special tools or glass-cutting are required, but follow safe removal steps for the broken original glass to avoid injury.

What driving conditions does the heated convex mirror improve?

The convex curvature increases lateral visibility to reduce blind spots and the electric heating function helps keep the mirror clear from light frost, drizzle, and fog buildup. Together they provide improved sightlines during common adverse weather and while towing or changing lanes.

• Convex glass widens the field of view for better lane-change awareness.
• Integrated heater helps remove condensation and light ice accumulation.
