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.

LOVE THEM!!
Size: Small, Color: (001) Black / Black / Castlerock
LOVE! These socks are so comfortable! I wear a 5 in women's and a 3 in big kid shoes. The small fit me perfectly. I see where some say they run small but I can't say that was an issue for me. They are "snug" but thats what you want with a no show sock. I feel they have support vs the ones i used to buy at Walmart. They are very soft! I am actually buying more today and throwing my other ones in the trash!

So will not write down your foot
Size: Medium, Color: (001) Black / Black / Castlerock
I love these socks. They have a little bit of gel on the top of the heel for support in your tennis shoes and so your socks don’t write down. Very good quality.

Comfy and Stay Put
Size: Medium, Color: (002) Black / Black / Halo Gray
These socks are honestly great. They’re super thin and light, so once you have them on, you kind of forget they’re even there. No bulky feeling in your shoes at all.
The best part is they actually stay on. I hate no-show socks that slide down after five minutes, and these don’t do that. The little grip on the heel really works, so you’re not constantly adjusting them all day.
They’re breathable too, which is nice if your feet run warm. They dry fast and don’t get that gross sweaty feeling. And there’s no annoying seam on the toe, so nothing rubs or feels uncomfortable.
Basically, they’re just comfy, stay put, and don’t cause problems — which is all I want from socks.

Amazing but quality changed
Size: Large, Color: (002) Black / Black / Halo Gray
Love these socks so much, been buying them for about 4 years now!! Not giving them 5 stars anymore because the quality is different and not as good, durable and thick as before.
