Blend Door USA HVAC Blend Door Repair Kit 03-12 GM 1500/2500/3500
If your heater or A/C is stuck on full blast or refuses to switch modes, odds are your factory blend doors have failed and it's a common issue in 2003–2012 GM trucks. But don’t worry, Blend Door USA has the permanent fix.
Their complete aluminum HVAC blend door replacement kit solves the problem once and for all, bringing back reliable temperature control to your Silverado or Sierra. But first, Delphi or Visteon? Before ordering, you’ll need to determine which HVAC box your truck has. The difference can only be identified by visual inspection, and it's easier than it sounds:
- Open your glove box and remove any items inside.
- Squeeze the sidewalls inward and let the glovebox drop down.
- You’ll now have a clear view of your HVAC box.
Compare what you see to the reference images. If the surface is smooth and the mode door area has a two-piece design, you’ve got the Visteon box. If you see vertical ribs on the HVAC box wall and a one-piece construction, then it’s the Delphi box.
This kit is specifically designed to match your setup once you’ve identified the correct box type, ensuring a proper fit and long-lasting repair. Like all Blend Door USA kits, it replaces the factory plastic doors with precision CNC-machined aluminum pieces, foamed with high-grade open-cell material and backed with 3M adhesive for airtight sealing and smooth operation. Say goodbye to temperature tantrums and airflow issues, this is the upgrade your GM deserves.
