Fixes Broken Vent Louver Tab | Restores Full Directional Control | PETG
The tiny plastic tab that lets you aim your A/C vent louvers is one of the most famously fragile interior parts on BMW E46 and E39 cars — it snaps off with age, leaving the vent stuck or impossible to aim. This replacement slider tab restores full directional control without replacing the entire vent assembly.
Printed in a durable PETG blend for heat resistance near the dash, this part snaps in place in seconds and instantly brings your vents back to life.
🔧 Features
🧩 Direct‑fit replacement for the broken vent slider tab
🚗 Fitment: BMW E46 (3 Series) & E39 (5 Series)
🔥 Material: PETG blend — heat‑resistant and long‑lasting
📦 Sold per tab — order exactly the quantity you need
🛠️ No tools required — installs in seconds
Made to order in Chattanooga, TN
If you’re unsure how many tabs your vent needs, send a photo and I’ll help you figure it out.
⚡ Quick Install Instructions
(These steps are based on standard BMW E46/E39 vent slider replacement.)
1️⃣ Remove the vent assembly (optional)
You can replace the tab with the vent still installed, but removal makes alignment easier.
2️⃣ 🔍 Locate the broken slider tab
It’s the small plastic piece that connects the adjustment slider to the louver mechanism.
This is the part described in your listing as the “plastic tab that lets you aim your A/C vent louvers.”
3️⃣ 🧹 Clear out any broken fragments
Remove any snapped OEM plastic so the new tab seats properly.
4️⃣ 🔩 Snap in the new PETG tab
Press the replacement tab into the slider track until it clicks into place.
No tools required — it’s designed to be a direct snap‑fit.
5️⃣ 🎯 Reconnect the slider to the louvers
Move the slider back and forth to ensure the tab engages the louver mechanism.
6️⃣ ✔️ Test full range of motion
Verify that the vent now aims smoothly in all directions.
📌 Notes
This is a single replacement tab — order multiples if several vents are broken.
PETG blend provides improved durability over brittle OEM plastic.
Works for both center and side vents on E46/E39.
