Chevy/GMC Delphi HVAC Kit (03-12) Dual Zone No Rear Vents – Blend Door USA

Your 2003–2012 Chevy or GMC’s dual-zone 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 Delphi 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 — Delphi HVAC box, Dual Zone, without rear vents on the center console

⚠️ How to confirm you have the right kit:
This kit is for vehicles without rear vents. Look through your glove box opening — confirm the Delphi box appearance matches the third product image. VIN number does not guarantee a match — visual confirmation through the glove box is the only reliable method. If your vehicle has rear vents on the back of the console, see our Delphi Dual Zone with Rear Vents kit instead.
