Installation recommendations
Generally/typically for replacing the interior dashboard vents, the exact steps may vary depending on the specific car design and mounting type.
1) Before assembly
- Compare with the old part shape, attachment, latch position and overall dimensions.
- Check designations/numbers: 9644589777 and HXN if applicable.
- Check the condition of the blades and the mechanism: smooth operation, unbroken guide parts, solid chrome slider.
- Visual check for broken locking lugs (common with used parts).
2) Necessary tools and materials
- Plastic crowbar for dismantling interior parts (trim tool)
- A small flat screwdriver (ideally with a tip guard)
- Cloth / protective tape to protect surrounding plastics
- Flashlight
3) Step-by-step assembly procedure
- Turn off the ignition and secure the car against movement.
- Protect the area around the part on the dashboard with a cloth or tape to avoid scratches.
- Use a plastic pry bar to carefully pry open the old vent (gradually around the perimeter, without brute force).
- Once the part starts to loosen, check where the latches are holding and loosen them gradually so they don’t crack.
- Remove the old vent and inspect the opening/seat (for parts of broken latches).
- Clean the contact surface from dust and dirt so that the new part fits properly.
- At first place the new part “dry” and check the correct orientation and alignment.
- Insert the vent into the hole evenly and gently press until the latches click.
- After clicking, check that the part sits flat all the way around and does not “stick out” anywhere.
- Test the mechanics of the slats and sliders: setting the direction and possible closing/opening must go smoothly.
-
4) Post-assembly checks and test drive/function verification
- Turn on the ventilation and verify that the air flows correctly and that the slats hold the set position.
- Listen for vibrations or rattling (may indicate a bad fit).
- For a short ride, check that the part remains firmly seated.
5) The most common assembly mistakes + how to avoid them
- Prying with a metal tool without protection → use a plastic pry bar and protect the surrounding plastics.
- Wrong orientation of the part → always “dry” test the fit before clicking.
- Not sitting down to the stop → after assembly, check the alignment and even engagement of all fasteners.
- Plastic embrittlement due to age and temperature changes in the interior (summer/winter).
- Mechanical overloading of slats and sliders (force adjustment, frequent handling).
- Reckless disassembly of on-board plastics – latches breaking off and the frame cracking.
- Dust contamination which impairs the operation of the mechanism and leads to its grinding.
