Frequently Asked Questions About Freightliner Century 112/120 AC Vents

Will these AC vents fit my specific Freightliner Century model year?

These AC vents are designed to fit Freightliner Century Class 112 and 120 models manufactured from 1996 to 2011. However, there were minor dashboard variations in 2004-2005 model years that may affect fitment. We recommend verifying your dash configuration before ordering, especially if you have a 2004-2005 model. The vents are direct replacements for OEM part numbers A18-28879-003 and A18-28879-004.

How difficult is it to replace the AC vents, and what tools do I need?

Replacing Century AC vents is a straightforward process that typically takes 15-30 minutes per vent. You'll need a trim removal tool or flat-head screwdriver wrapped in cloth to prevent scratching, and possibly a Phillips screwdriver depending on your model. The vents are held in place by clips that can become brittle over time, so gentle pressure is key. Most drivers can complete this installation without professional help.

What's the difference between chrome and black vents, and which is more durable?

We offer both chrome-plated and matte black finishes. Chrome vents provide a classic, polished look but may show fingerprints more easily. Black vents offer a modern appearance and tend to hide dust better. Both options use the same ABS plastic construction with UV-resistant coating. In terms of durability, both perform equally well, lasting 5-7 years on average with proper care. The choice is purely aesthetic based on your interior preferences.

Why do Century AC vents break so frequently, and how can I prevent it?

Century AC vents commonly fail due to sun exposure causing the plastic to become brittle, especially on the driver's side. The louvers and adjustment tabs are the first to break. To extend vent life, use a UV protectant spray monthly, avoid forcing stuck louvers, and consider window tinting to reduce sun exposure. When adjusting airflow, always move the louvers gently from the center, not the edges.

Can I buy individual vents or do I need to purchase a complete set?

We sell AC vents both individually and in complete sets. Individual vents are perfect for replacing a single damaged unit, while sets of 4 or 5 (depending on your dash configuration) offer better value and ensure uniform appearance. Most Century 112/120 models have 4 dash vents, but some configurations include a fifth center vent. Check your current setup to determine the quantity needed.
