Frequently Asked Questions About Kenworth T680 AC Vents

Will these AC vents fit my specific year model T680, and are there any differences between model years?

Most aftermarket AC vents are designed to fit Kenworth T680 models from 2013 to present. However, there were minor dashboard updates in 2018 that may affect fitment of certain vent styles. Pre-2018 models typically use vents with a slightly different mounting tab configuration. Always verify the specific part number matches your truck's VIN year before ordering. If you're unsure, our customer service team can help confirm compatibility with your exact model year.

Are these vents direct replacements, or will I need to modify my dashboard?

Quality aftermarket AC vents for the T680 are designed as direct bolt-in replacements requiring no dashboard modifications. They should match the OEM mounting points exactly and use the same clip-style or screw-mount installation as your original vents. The entire replacement process typically takes 10-15 minutes per vent with basic hand tools. If a vent requires cutting or drilling, it's likely not the correct part for your application.

What's the difference between OEM and aftermarket vent quality, and will aftermarket vents hold up to daily use?

OEM vents are made from high-grade ABS plastic with UV stabilizers and typically last 8-10 years. Quality aftermarket vents use similar materials but may vary in thickness and UV protection. Look for vents specifically marked as UV-resistant to prevent cracking and fading. Chrome-plated options should have a proper base coating to prevent peeling. While aftermarket vents may not match OEM longevity exactly, reputable brands offer 2-3 year warranties and cost significantly less than dealer replacements.

My vents won't stay in position or the louvers are loose - is this a common problem with replacements?

Loose louvers are often caused by worn internal friction points rather than the vent housing itself. When replacing vents, ensure you're getting complete assemblies with new louver mechanisms, not just the outer housing. Some aftermarket vents use stronger spring tensions than OEM to maintain position better. If your original vents failed due to excessive sun exposure or heat damage, consider upgrading to reinforced aftermarket versions designed specifically for high-temperature resistance.

Can I replace just one broken vent, or should I replace all of them for appearance consistency?

While you can replace individual vents, color matching can be an issue, especially with older trucks. New black vents may appear darker than sun-faded originals, and chrome finishes can vary between manufacturers. For the best appearance, we recommend replacing vents in pairs (left and right) at minimum. Many drivers choose to replace all dashboard vents simultaneously to ensure uniform appearance and take advantage of kit pricing, which typically offers 15-20% savings over individual vent purchases.
