Chevy/GMC Visteon HVAC Repair Kit (03-12) – Blend Door USA

Your 2003–2012 Chevy or GMC’s heat is stuck on one temperature, the A/C won’t respond, or you’re hearing a clicking noise from behind the dash. The plastic blend doors inside your Visteon HVAC box have cracked or broken — a known failure on this platform. This kit from Blend Door USA replaces them permanently with CNC-machined solid aluminum doors that won’t crack again.

Fits: 2003–2012 Chevy Silverado, Tahoe, Suburban, Avalanche & GMC Sierra, Yukon, Yukon XL — Visteon HVAC box only

⚠️ How to confirm you have a Visteon box:
Look through your glove box opening. The Visteon box has no structural ribs on the heater box and is bolted together in two pieces in the mode area. See the product images for a visual reference. VIN number does not guarantee a match — visual confirmation is the only reliable method.

Why replace it?

• Heat or A/C stuck at one temperature regardless of dial position
• Clicking or ticking noise from behind the dash
• Temperature or mode control unresponsive or intermittent
• Plastic OEM doors cracked or broken

What’s included:

• CNC-machined solid aluminum blend door replacements (foam-sealed)
• Installation drivers (secured in the doors with clear tape — as shown in product images)
