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.

Would recommend
Size: 10 sqft
I used this sound deadening material in my car during an audio and interior upgrade, and the difference was noticeable immediately. Road noise, vibrations, and rattling were reduced a lot, especially on the doors and floor panels. The car feels much quieter and more solid while driving now.
The material was easy to cut and apply, and the adhesive stuck very well without peeling up. It has a quality feel to it and conforms nicely around curves and tight areas. I also noticed my speakers sound cleaner and have better bass response after installing it.
For the price, this sound deadening material is a great value and definitely worth it if you want a quieter ride and better overall sound quality in your vehicle.

Worth it!
Size: 50 sqft
I was worried it wouldn't work as well since it's 50 mil and I thought I got the wrong thing. Nope! Works great. Did all four doors on my 93 civic and I have enough for the floor I think. Solid price. Noise reduced by about 5 decibels hive difference. Very sticky and easy to apply I'm so happy I was able to cover most all of my car. If I need more, definitely buying this since I got so much extra and I thought I would.
PS: that five decibel thing is only with the four doors. My firewall is next and then my floor, but it's such a huge difference

Quiet your vehicle noises
Size: 50 sqft
Put this in our high roof van and couldn’t believe how much quieter it was at once. Really cut down on the vibration noise Nice and easy to install just peel n stick. Was also easy to cut with scissors for smaller areas. Seemed to be really nice quality. Didn’t notice any odor.
