Installation recommendations
Generally/typically for interior rearview mirror replacement, the exact procedure may vary depending on the car model and type of attachment. Always compare the new part with the original one before assembly.
1) Before assembly (checks of used part)
- Check the glass (cracks, detachment), mirror body and joint (play, stuttering).
- Verify auto-dimming mirror type fits and codes 8149ST / 8149XK / 8149XN match your original part.
- If the mirror is electric, check the condition of the connector and pins (bent/corroded).
2) Necessary tools and materials
- Basic set of screwdrivers / bits (according to design)
- Plastic pry bar for removing covers (so as not to damage the lining)
- Clean cloth and mild cleaner to degrease the contact surfaces
3) Step-by-step assembly procedure
- Secure the vehicle against movement and prepare a working space in the interior.
- Typically disconnect the battery, especially if the mirror has an electrical connector (to reduce the risk of a short circuit).
- Carefully remove any plastic caps at the base of the mirror (if any).
- For a mirror with a connector, disconnect the electrical connection (do not pull on the cables, but on the body of the connector).
- According to the type of attachment, release the mirror (most often shifting/turning from the foot or releasing the lock) and remove it.
- Clean the bearing surface/mounting area from dust and grease.
- Place the new mirror in the same position as the original and secure it in place.
- Connect the connector (if used) and check that it clicks into place and that the cable is not pinched.
- Refit the caps/coverings if removed.
- Plug in the battery (if it was disconnected).
-
4) Post-assembly checks and test drive/function verification
- Check the stability of the mirror (without self-folding and play in the joint).
- Verify the auto-dimming function (if it is active on the car and the mirror is connected).
- When driving, check that the mirror holds the setting even on bumps.
5) The most common assembly mistakes + how to avoid them
- Damage to covers/trimming – use a plastic pry bar and proceed slowly.
- Tearing out wiring or bending pins – always disconnect connectors by pulling on the connector, not on the cable.
- Incorrect locking in the mounting – after mounting, gently push the mirror/check if it is really locked.
Reasons why the part is damaged
- Mechanical damage (hitting the mirror, careless handling when cleaning the interior or disassembling the front accessories).
- Joint wear and locking – then the mirror does not hold the setting or has play.
- Glass damage (cracks, scratches, impaired visibility).
- Auto dimming malfunction – due to the age of the electronics, moisture or poor contact in the connector (if used).
