Tired of playing the hot-or-cold guessing game every time you get in your truck? If your heater or A/C isn’t doing what it’s supposed to, chances are your factory blend doors are the culprit, and you're not alone. The 1999–2002 GM trucks are known for weak plastic HVAC doors that warp, crack, or flat-out stop working. That’s where Blend Door USA steps in with a real solution.
This complete repair kit replaces all four blend doors inside the HVAC box with solid CNC-machined aluminum upgrades, built to outlast the life of your truck. They come foamed with premium poly ether open-cell foam backed by high-strength 3M adhesive to ensure a tight seal and proper airflow every time. Designed specifically for single-zone systems, this kit fits your 1999–2002 Chevy Silverado or GMC perfectly and it’s the last HVAC fix you’ll ever need.
Keep in mind, this kit does not include new blend door drivers, you’ll reuse your original plastic OEM ones. If your HVAC box looks like the photo (through the glovebox), you’re in the right place. Get rid of the guesswork, fix your climate control for good, and enjoy a cabin that finally listens to what temp you want.

Heavy duty brackets!
Size: 8 Inch, Color: Gold, Size: 8 Inch, Color: Gold
These brackets are heavy duty and came with the correct hardware. They were easy to install, the two holes were so helpful to know where to mark them. I think because they’re heavy duty you can place a good amount of weight on your shelves. The only thing I wasn’t happy with is that 4/69 of shelves, the paint was chipping but it was the perfect gold color.

Don't hesitate - Great product!
Size: 12 Inch, Color: Black
Superior quality at an unbelievable savings over local retailers. Hardware for hanging included the cheaper plastic lags yet they also included the heavy duty lags, so no tapping in to our supply. Thank you for a great product
