A situation where the car stops responding to the turn of the external handle often takes the owner by surprise. The door is locked, and inside may be something valuable, or simply impossible to get into the cabin. In the vast majority of cases, the culprit of this malfunction becomes plastic clipper. This tiny element costing several tens of rubles is able to paralyze the work of the entire locking mechanism.
Design of door locks of modern cars, whether it is a budget Renault premium BMWIt is built on a system of levers and rods. A traction is a thin metal rod that transfers force from the handle to the lock. It is the plastic fixator that keeps this rod in the correct position, preventing it from jumping off during vibrations or impacts. Over time, plastic loses its elasticity, cracks and breaks down.
In this article, we will discuss in detail how to diagnose the problem, what tools will be required for repair and why the use of the device is not possible. original It is often more profitable than finding analogues. You will learn how to avoid common mistakes that can lead to the breakage of the handle itself or the lock mechanism. Repairs do not require complex equipment, but require accuracy and understanding of the principles of the door system.
Door mechanism design and the role of the retainer
To understand the importance of a small plastic element, it is necessary to consider the general principle of operation of the door drive. When you take the outer handle and pull it on yourself, you act on the lever connected to the thrust. This thrust passes through the interior space of the door and rests on the trough of the castle. Clip of traction in this system performs the function of a hinge connection or a stopper, fixing the end of the thrust in the landing place of the handle.
Without reliable fixation, the thrust simply slips off and the force is not transmitted. The mechanism becomes "idle." Car manufacturers use different types of fasteners. Older models often featured metal staples that required pliers to be mounted, but modern cars are dominated by plastic. It is cheaper to produce, is not susceptible to corrosion and provides sufficient strength under normal operating conditions.
But plastic has enemies. The main one is temperature drop and ultraviolet radiation. In winter, the material becomes fragile, and in summer, heating up in the sun, softens and deforms. That is why breakdowns often occur in the off-season or after a long parking in the cold. The inner handle. It may also have a similar fixator, but the external one suffers more often due to direct contact with the environment.
It is important to understand that the craving may not be alone. In doors with a central lock and electric drive may be a second traction, responsible for locking. It is also secured with similar fixtures that can fail. Therefore, when disassembling the door, it is recommended to inspect all plastic elements.
β οΈ Attention: Never forcefully pull a jammed handle if you suspect a break in the lock. You can break the handle itself or damage the teeth of the lock mechanism, which will lead to the need to replace the entire assembly.
Structurally, fixers are divided into several types according to the method of installation. Some simply snap into the groove, others require a 90-degree tilt, and still others have a screw mount. Type of attachment It has a direct impact on the complexity of the replacement and the tool needed. Knowing the type of your fixture will help you prepare for the repairs in advance.
Symptoms of malfunction and primary diagnosis
Determine that the problem lies in the clip of thrust, it is possible by characteristic signs that appear long before the complete failure of the mechanism. The first bell is often a fuzzy stroke of the handle. It can fall deeper than usual or, conversely, walk too tight. This suggests that the traction began to "walk" in the landing place due to wear of the fixing antennae.
The second symptom is a characteristic knock or rattle coming from the door when driving on an uneven road. Metal traction, devoid of rigid fixation, begins to beat against the internal elements of the door frame. If you hear this sound, itβs worth rushing with repairs, as the dangling traction can damage the wiring insulation or door membrane.
Complete rejection of work is the final stage. The handle is free, without resistance, but the door won't open. At this point, the thrust has already completely fallen out of the hook. Diagnosis in this case is simple: if you press the inner handle when the door is open and the lock is triggered, and the external one does not respond, then the problem is 99% in the connection of the external traction.
For accurate diagnosis, it is sometimes necessary to remove the skin of the door, but you can often do with a visual inspection through the process holes, if any. Use a flashlight to illuminate the inside of the handle. If you see the traction hanging loosely or the plastic tip split, the diagnosis is confirmed. Visual examination allows you to assess the scale of the disaster: it may be necessary to replace not only the clips, but also the thrust itself, if it is deformed.
Necessary tool and preparation for repair
Replacement of clips of the thrust of the door handle is a procedure that is within the power of even a novice motorist, but it requires some preparation. First of all, you need to get the right tool. You wonβt need a heavy mechanical set, but specific devices will be extremely useful. The basis will be a set of plastic blades for removing clips of the skin, as metal screwdrivers can damage the cabin.
To work with the mechanism itself, thin sponges, a sewer or a medical clamp will be needed. These tools will help to tamper with and extract the remains of the old fixator from hard-to-reach places. Also prepare a flashlight, as the interiors of the door are poorly lit, and it is almost impossible to consider small details in the twilight. It will also be a bit more lubricant, for example. lithium-lubricant or WD-40, for the treatment of rubbing surfaces.
Before starting work, be sure to de-energize the car by removing the terminal from the battery. This is critically important, as there are many electrical wires running through the doors, from windows to speakers and a central lock. A random circuit can disable the comfort control unit. In addition, many modern cars require careful handling of airbags if they are integrated into doors (although this is rare).
βοΈ Preparation for door repair
Organize the workplace. You will need a clean surface to spread the removed screws and parts in the order in which you shot them. A lost screw or tangled clips can turn a simple renovation into a multi-hour quest. In advance, find a manual or video for disassembling your model of the car, as the location of the fasteners is different for everyone.
Step-by-step instructions for replacing the fixator
The replacement process begins with the removal of the door card. This is the most time-consuming stage. First, unscrew all visible screws: they can hide under decorative plugs, in the opening handle or at the bottom of the map. Then gently flick the plastic locks around the perimeter of the door using a plastic shoulder blade. Movements must be confident, but without jerks, so as not to break the fragile pistons.
After removing the card, you will see polyethylene noise insulation. It must be carefully peeled off, trying not to break, so that later it can be glued back. You will have access to the internal mechanism of the door. Find the thrust coming from the outer handle. It's usually very visible. If the old fixator is still holding, but hanging around, it needs to be removed. This often requires twisting it or squeezing the mustache.
Installing a new clip requires care. Put the thrust in the hole of the handle to the point. Then put on a new lock. You should hear a characteristic click. If the clip is screwed or with a rotary mechanism, make sure it is fixed in the closed position. Check the traction with your hand: it should move freely, but not fall out of the grip.
β οΈ Attention: When installing new clips, do not apply excessive force. Plastic can crack if you overdo it. If the fixture does not stand in place, check whether you have chosen the correct size and whether something interferes with the installation.
After installation, collect everything in reverse order. Do not forget to check the mechanism until the final twist of all screws. Attach a door map, connect connect connectors and check if the door opens from the outside and from the inside. If everything works correctly, you can finally fix the skin and enjoy the result.
Comparative table of anchorage types
There are many types of car parts in the market. They differ not only in the manufacturer, but also in design. Below is a table that helps identify the type of mount that is used in your car. This will help you to choose the right remix.
| Type of clips | Description of design | Replacement tool | Common stamps |
|---|---|---|---|
| Rotary (Rotary) | It has a slot, requires a rotation of 90 degrees after installation | Shiloh, thin screwdriver. | VAG, BMW, Mercedes |
| Clicking (Snap-on) | It is worn on top and fixed by the mustaches. | Fingers, thin-slips | Renault, Ford, Kia |
| Screwing | Wrapped into the body of a handle or traction | Little cross screwdriver. | Japanese cars (Toyota, Honda) |
| Bracket (Metal Clip) | Metallic P-shaped bracket (obsolete type) | Flat-deaders | Old models of VAZ, GAZ |
As you can see from the table, different approaches are required for different types. Turning clips They are the most reliable, but require accuracy in installation. Clicking The options are easier to install, but over time can be spread out. Screws are less common, but they are harder to lose because they are tightly pressed to the surface.
When buying a remake, pay attention to the material. Good clips are made of polyamide or reinforced plastic, which retains its properties at low temperatures. Cheap polyethylene in the cold will turn into a crumb, and the repair will have to be repeated.
Where to buy quality clips?
It is best to look for original parts numbers in dealersβ catalogs or specialized fastener stores. In the markets, low quality universal sets are often sold. You can also order knobs for your particular model β they often contain all the necessary fixers and lubricant at once.
Frequent repair mistakes and helpful tips
One of the most common mistakes is to ignore the state of the thrust itself. If the metal bar is bent or has burrs at the end, the new clip will not live long. The burrs will loosen the plastic hole, and the bend will create a constant stress. Before installing a new fixture, be sure to inspect the thrust and, if necessary, straighten it or clean the edges.
Another mistake is using the wrong lubricant. Some craftsmen lubricate plastic nodes with graphite lubricant or solidol, which may contain aggressive chemicals that corrode plastic. Use only those lubricants that are labeled "Safe for plastics" or "For plastic parts". Ideal is silicone lubricant or white lithium.
Lubricate the new clip with silicone lubricant before installation. This will prolong her life, prevent freezing in winter and facilitate future repairs.
Do not try to βreanimateβ an old cracked clip with superglue or soldering. This is a temporary measure that will lead to a re-break at the most inopportune time. The cost of a new part is negligible compared to the risk of being left with a jammed door in the shopping center parking lot.
When assembling a door card, watch the wires. It often happens that the speaker wire or window lifter falls under the screw or is clamped by the window lifter mechanism. This can lead to a short circuit or a chain break. Carefully put the harnesses in regular places.
Questions and Answers (FAQ)
Can you make a thrust clip yourself from wire or plastic?
Theoretically, it can, but in practice, itβs a bad idea. Homemade wire will not provide the necessary fixation and will rattle, and plastic of an unknown brand can burst in the cold. It is better to buy a universal remake, which is inexpensive.
Why did the car break down when no one was using it?
Plastic is aging. Under the influence of ultraviolet light and temperature changes, it loses plasticity. Even without mechanical impact, the old clip can simply crumble from time to time.
Do I need to change both clips on the door if one breaks down?
It is advisable to replace all the thrust locks on this door prophylactically. If one element has already collapsed due to aging, the second element is likely in a similar state and will soon need to be replaced.
What to do if the ear of the mount on the handle itself is broken?
If the plastic of the handle itself burst at the place of thrust attachment, then replacing the clips will not help. You will need to replace the entire door handle. In rare cases, repairs with epoxy glue and reinforcement are possible, but this does not guarantee durability.
Timely replacement of cheap plastic clips saves from expensive repair of door locks and handles. Donβt ignore the first signs of backlash.
