Many owners Skoda Octavia A7 face the need to repair rear-view mirrors, whether it is replacing broken glass, repairing electric motors drive or fixing heating problems. Official dealers often offer a complete replacement of the assembly, which results in an impressive amount, while self-disassembly allows you to save significant funds.
The process of dismantling and disassembly does not require complex specialized equipment, but implies accuracy and knowledge of the structural features of the body. In this article, we will take a detailed look at each step of the job, from removing the plastic lining to accessing the internal components so you can complete the task without damage.
Preparing tools and work area
Before you start the physical impact on the car, you need to organize a comfortable workspace and prepare the right set of tools. Working with plastic elements requires a delicate approach so as not to leave scratches on the body paint or break fragile fixtures.
You will need a set of plastic blades to remove the skin, a cross screwdriver, a thin flat screwdriver with rounded edges and, preferably, a dryer for heating. Also, be sure to prepare a container for small screws and fixtures so that they do not get lost in the process.
- ๐ง Plastic spatulas for removing panels
- ๐จ Screwdriver set (phillips and flathead)
- ๐ฆ Hair dryer construction or household (for heating glue)
- ๐งค Microfiber gloves to protect the hands and body
โ ๏ธ Warning: Make sure the car is on a flat surface and the gear lever is in neutral or parking mode to avoid accidental movements of the gears.
Removing a mirror from a car door
The initial stage of work is to carefully remove the mirror from the door map. In models Octavia A7 The mirror is mounted through an internal plastic lining that covers the fasteners and wiring. This stage requires the greatest concentration, since there are fixtures that can easily break with a careless jerk.
First, you need to remove the triangular lining from the inside of the cabin. It is held on to a few plastic clips and sometimes on a screw hidden under a stub. Push it with a spatula, starting from the lower edge, and gradually snap the locks around the perimeter.
After removing the lining, you will get access to three bolts of the mounting of the mirror body. Unscrew them, remembering to hold the mirror with your hand so that it does not fall and damage the wiring. Carefully remove the body from the door, removing the connector of the wire harness.
- ๐ Open the door and find the triangular plug.
- ๐ฉ Unscrew three bolts of body mounting
- ๐ Carefully disconnect the electrical connector
What should I do if the latches do not snap off?
If the clips are sitting very tightly, do not use force. Use a hair dryer to slightly warm up the edge of the lining, the plastic will become more elastic, and the locks will come out without breaking.
Disassembly of the mirror body and access to mechanisms
Now that the mirror is removed, you can proceed to its immediate disassembly. The mirror body consists of two halves connected by latches and adhesive layer. Depending on the configuration, there may be electric motors, heating elements or blind spot sensors inside.
To open the body, it is necessary to carefully tuck the joint of two halves. It is better to start from the bottom, where the load on the fixers is less. Use a thin screwdriver, laying it between the cases so as not to damage the paint. Be careful with wires going to the glass as they may be glued or clamped.
After the latches are snapped, split the halves of the body. Inside, youโll see control boards if the mirror has auto-darking function, or just mechanical mounts. Pay attention to the location electric motorsReplacing them is a common reason for this.
- ๐ Put the body in the joints below.
- ๐ก Examine the internal wiring for fractures
- โ๏ธ Remove the motors if necessary.
โ ๏ธ Warning: When splitting the case, be extremely careful with the heating wire of the glass. It is very thin and often passes through the joint, it is easy to cut with a screwdriver.
- Broken glass
- The electric drive does not work
- Not warming.
- Turn signal doesn't work
Replacement and removal of mirror glass
The most common operation is to replace the glass itself. V Octavia A7 The glass is attached to the base (mirror element) using double-sided tape and sometimes plastic fixtures. If the glass is broken, it must be removed as carefully as possible so as not to damage the substrate.
If the glass is whole but needs to be replaced (for example, with aspherical or auto-darking), it must be unstuck. Use a dryer to heat the scotch to a temperature of about 60-70 degrees. Smoothly, without jerks, bend the glass from the base, moving in a circle.
After removing the old glass, clean the base of the residues of glue and scotch. Use isopropyl alcohol or a special cleaner, but avoid aggressive solvents that can damage the base coating. The new part is attached to a fresh layer of quality scotch.
Before sticking a new glass, be sure to degrease the surface of the base and let it dry completely - this is a guarantee that the mirror will not fall off in a month.
Electrical and heating repair
Often the cause of disassembly is a broken electric drive or lack of heating. In the case there are two small electric motors responsible for vertical and horizontal inclinations. Check their performance by supplying power directly from the battery or multimeter.
If the motors are in good working order, the problem may be in the gears of the plastic gearbox. Over time, the plastic wears off and the mechanism stops transmitting force. In this case, you will need to replace the entire gearbox or motor assembly, since gears are rarely sold separately.
Heating problems are most often associated with a break in the conductive tracks on the glass itself or poor contact in the connector. Ring the chain with a multimeter. If the tracks are intact, check the fuse and relay in the cabin block responsible for heated mirrors.
| Component | Symptom of malfunction | Repair method |
|---|---|---|
| Electric motor | Lack of movement when pressing buttons | Replacement of motor or gearbox |
| Glass | Cracks, chips, lack of image | Replacing glass with a new one |
| Heating | The glass doesn't heat up. | Contact and track checks |
| Housing | Luft, plastic cracks | Replacement of the shell or gluing |
Assembly and installation on the vehicle
After performing all the necessary repair operations, the reverse assembly process begins. Make sure all wires are laid neatly and do not twist when the glass moves. Close the halves of the body, pressing until the characteristic click of the locks.
Before installing on the door, check the operation of all functions: drive, heating, turn-key. This will avoid re-disassembly if you accidentally forgot to connect some connector. Set the mirror in place, tighten the fasteners and connect the wire harness.
Return to the place of the triangular lining inside the cabin. Make sure all clips have entered their seats. If you used a hair dryer to heat the plastic, let it cool for a few minutes to keep it in shape.
- ๐ Check the operation of all buttons on the mirror
- ๐ฉ Tighten the mount bolts with moderate effort
- ๐งน Wipe the glass and body from finger marks
High-quality assembly of the body guarantees the absence of extraneous noise and vibration when the car moves at high speeds.
Common mistakes when disassembling yourself
Experienced craftsmen know that most often damage occurs not due to breakdown of parts, but due to careless actions. The most common mistake is the use of excessive force when removing plastic linings. This leads to breaking off the ears, which can then not be fixed without glue.
Another mistake is ignoring the temperature regime when working with scotch. Cold Scotch holds very tightly, and trying to unplug the glass without heating can cause you to damage not only the glass, but also the base of the mirror, making repair impossible without replacing the entire unit.
You should also avoid using metal tools directly on visible surfaces. Even the thinnest screwdriver can leave deep scratches on chrome elements or body paint, which will spoil the appearance of the car.
โ ๏ธ Warning: Never try to disassemble a mirror if it is heavily polluted with dust or dirt. Clean it first, otherwise the abrasive particles will get inside the mechanism and disable it.
