Owners of a popular budget sedan Daewoo Nexia Often faced with the problem of the quality of standard body elements, and side mirrors are no exception. Plastic fades over time, mechanical drives become loose, and the lack of heating in basic configurations causes discomfort in winter. That is why many car enthusiasts are considering the option of installing mirrors from more modern domestic cars, in particular from Lada Granta.
Such a replacement allows you not only to refresh the appearance of the car, but also to obtain a functional electric drive heated for a very reasonable price. The remodeling process requires accuracy and basic electrical skills, but it is quite feasible in a garage. In this article we will analyze in detail the technical nuances, the necessary tools and a step-by-step algorithm for successful modernization.
It is worth noting that the fastening geometry of these models is different, so simply “screwing on” new parts will not work—the seats will need to be modified. However, the results are worth it: improved visibility, reliable design and aesthetics that meet modern standards. Let's look at exactly what this project will require and what challenges you may encounter.
Advantages of replacing standard Nexia mirrors
Standard mirrors Nexia, especially early years of production, are structurally simple, but their reliability leaves much to be desired. The adjustment mechanism often sours or, conversely, becomes too tight, and the mirror element can rattle while moving. Installation of analogues from VAZ solves these problems by providing a more rigid body design and quality optics.
One of the main arguments in favor is the opportunity to get heating and electrical adjustment. In winter, this is critically important for safety, as it allows you to quickly clear the surface of ice and fog. In addition, modern mirrors often have a more aerodynamic shape, which has a positive effect on cabin noise insulation at high speeds.
- 🚗 Visibility is significantly improved due to the increased area of the reflective surface.
- 🔥 A heating function appears that eliminates condensation and ice crust.
- ⚡ Electric adjustment allows you to adjust the viewing angle without leaving the salon.
- 🎨 More modern design improves the overall aesthetics of the car.
Don't forget about the availability of spare parts. If the mirror element breaks or the motor fails, find spare parts for Grants in any auto store it is much easier and cheaper than looking for originals for a car that has already been discontinued Daewoo. This makes operating the car more comfortable and economical in the long run.
Required tools and materials
To perform high-quality work on replacing and modifying fasteners, you will need to assemble a certain set of tools. Since you will have to work with both plastic and electrical wiring, it is important to prepare in advance so as not to interrupt the process by searching for the right screwdriver or soldering iron.
The bulk of the work will have to do with adjusting the seats, since the standard holes on the door Nexia do not match the mirror mounting points Grants. You will need a drill, a set of metal and plastic drill bits, and edge cleaning tools. You also cannot do without sealing materials to prevent moisture from getting inside the door card.
☑️ Preparation for installation
For the electrical part, it is critical to use quality materials. The wires must have a cross-section of at least 0.75 mm² in order to withstand the current consumption of heating elements and motors. It is better to solder all connections and insulate them with heat shrink, since the twists in the doorway quickly oxidize from moisture.
Removing old mirrors and preparing the place
The first stage of work is to carefully remove the standard mirrors. On Daewoo Nexia This process is usually straightforward, but requires care not to damage the door paint or interior trim. First you need to remove the decorative plug or triangle in the corner of the window if it blocks access to the fasteners.
After gaining access to the inside of the door, disconnect the electrical connectors. Even if you had simple mechanical mirrors, there may be wiring for turn signals or speakers. Carefully unscrew the mounting bolts and remove the old assembly. Now you need to try on a new mirror from Grants and evaluate the scope of drilling work.
⚠️ Attention: Before starting drilling, be sure to cover the area around the intended holes with masking tape. This will prevent scratches from the drill bit slipping and paint chipping.
Often it is necessary to widen existing holes or drill new ones. It is important to maintain symmetry so that the mirror does not warp. Use a caliper to accurately measure the distances between the new mirror mounting studs and transfer these measurements to the door card.
Installation of fasteners and installation of housings
Installing new enclosures requires precision. If the holes do not match even by a couple of millimeters, the adjustment mechanism may jam or, conversely, dangle. In some cases, enthusiasts use adapter plates made of metal or durable plastic, which avoid drilling unnecessary holes in the door, but this adds complexity to the design.
When fastening directly, use bolts with wide washers and lockers so that vibration during movement does not weaken the connection. It is recommended to apply a small amount of thread locker under the bolt head. After installing the housing, check the movement of the mechanism: it should move smoothly, without creaking or jamming.
Nuances of sealing
After installation, be sure to apply automotive sealant around the perimeter of the mirror’s contact with the body. Water getting under the mirror can corrode the metal of the door or damage the electrics, so this step cannot be ignored.
Having completed the mechanical installation, assemble the inner door trim, but do not tighten all the screws tightly yet - the electrical connection stage lies ahead, and access to the inside of the door will still be required. Make sure that the wires are not pinched and have sufficient length for the window regulator to move freely.
Electrical and heating connection diagram
The most important part of the work is the connection electric drive and heating elements. Standard wiring Nexia most often it does not have connectors for connecting adjustment motors, so the wires will have to be pulled from the control unit or new wiring must be made. For control, a separate joystick is usually used, which is installed on the dashboard or in the door card.
Heated mirrors are usually powered through a relay, controlled by a button or automatically when the dimensions/ignition are turned on. It is important not to forget to install a fuse on the heating power circuit, since the current consumption there is quite high. The connection diagram must be reliable to prevent short circuits.
| Function | Wire color (approximate) | Purpose | Connection point |
|---|---|---|---|
| Motor power supply | Red | Plus 12V | Battery via fuse |
| Weight | Black | Grounding | Car body |
| Heating | Yellow/Blue | Heating element | Relay or button of dimensions |
| L/R control | Green/White | Choosing a side | Joystick adjustment |
Use corrugated tubing to connect the wires inside the door to protect them from chafing. Pay special attention to the place where the harness passes through the hole in the door - wires often break there due to constant opening and closing.
Use a multimeter to test each wire before final assembly. This will help avoid a situation where, after assembling all the panels, it turns out that one of the mirrors does not work due to poor contact.
Setting up and checking the system operation
After all the wires are connected and insulated, it is necessary to conduct an initial test. Apply power to the system and check the operation of the joystick: the left and right parts should respond correctly, without mixing up the sides. If the directions are reversed, check the connection diagram to the joystick connector.
Heating is checked tactilely or visually. Turn on the heating system for 3-5 minutes and gently touch the surface of the mirror (be careful, it may be hot). You can also use a thermal imager or simply notice the disappearance of condensation when fogging. If heating does not work, check the continuity of the circuit and the presence of voltage at the contacts of the mirror element itself.
- ✅ Make sure the mirror does not vibrate when the engine is idling.
- ✅ Check whether the mirror body does not touch the door elements when folded.
- ✅ Make sure that the viewing angle allows you to see the side of the car and the marking strip.
⚠️ Attention: Do not leave the heated mirrors on for a long time without the engine running. This can lead to battery discharge, especially in winter.
Common mistakes and how to avoid them
When installing yourself, mistakes are often made that can lead to repeated disassembly. One of the most common is insufficient insulation of connections. There is moisture in the door, and if the twisting of the wires is not protected, within a month you will experience oxidation and system failure.
Another mistake is a careless attitude to geometry. If you drill holes by eye, the mirror may not look where you want it to, and its adjustment range will be shifted. In this case, you will either have to drill new holes or use adjusting washers, which is not always aesthetically pleasing.
High-quality preparation and accurate measurements take up 70% of the work time, but ensure that you do not have to redo the project again.
Sound insulation is also often forgotten. Standard mirrors Nexia may buzz, but new ones, if poorly attached, can create resonance. Use anti-vibration materials on the inside of the door frame and mirror housing to reduce noise.
Modernization results and recommendations
Replacing mirrors with Daewoo Nexia to analogues from Lada Granta is a great way to improve the comfort and safety of your car without major financial investments. You get modern functionality that was not originally provided for by the design, and increase the liquidity of the car in the secondary market.
The main thing in this process is not to rush and do everything carefully. Car electrics do not forgive negligence, so every contact must be reliable. If you doubt your abilities when working with a soldering iron or circuits, it is better to contact a specialized auto electrician.
The result is a car that looks fresher and comes with useful options. Properly installed mirrors will last for many years, providing a clear picture and no problems with icing.
Is it difficult to find a joystick for adjusting Granta mirrors?
No, this is a common part. It can be bought at any VAZ spare parts store, at a disassembly site, or ordered online. It is inexpensive and is often sold complete with wiring.
Is it possible to connect heating without a relay?
Theoretically, it is possible if the button can withstand the load current, but it is better to use a relay. This will reduce the stress on the button and wiring, making the system safer and more durable.
Do window regulators need to be replaced during installation?
No, replacing the mirrors does not affect the window lift mechanism in any way, as long as you route the wires carefully and do not damage the cables or racks of the mechanism.
What sealant is best to use?
It is optimal to use polyurethane automotive sealant or a special glue-sealant for glass. They are elastic, not afraid of ultraviolet radiation and temperature changes.
