In detail: DIY repair of wiper blades from a real master for the site my.housecope.com.
Hello everyone. Here is another update of my section "Crazy Hands". And as usual, we will do everything with our own hands and in the field.
I am sure that many motorists have an idea of what wiper blades are (among the common people - wipers), and the fact that they have plastic plugs on their sides that fix an elastic band that cleans the windshield from water, snow and dirt. It is this plug that we will repair today, or rather fix the rubber band, because the plug was lost somewhere along the way.
Immediately I apologize for the quality, I had to take pictures with a tablet with a lousy camera.
It was like this, we drove out of town, lost a plug on the way, there was not a single auto store in the neighborhood. There was nothing to be done, I had to repair it from available tools so that the windshield would not be scratched in the rain.
This is how the stub looks like:
And this is what we will be repairing:
As you can see from the photo, there is no plug at the end of the wiper blade (wiper), because of which the rubber band constantly runs away, and the "ribs" that should hold it - part and scratch the windshield, which can lead to unpleasant scratches.
The structure of the frameless wiper blade is extremely simple, and therefore it does not take much time to repair it. For repairs we need: 1. Stationery or construction knife; 2. Plastic tie-clamp (Zipties); 3. Self-confidence.
To begin with, I determined the place where the clamp will go in order to fix the elastic band tightly with it. If you look closely at the photo, you can see that the “ribs” have symmetrical indentations. It is precisely at their level that we will make a through hole in the wiper's elastic band for tight fixation of the clamp.
Video (click to play).
It is extremely inconvenient to make a hole, because the elastic is tight. Therefore, we do everything very carefully, and it is desirable that the hole is not very wide. The wider it is, the easier it is to tear the elastic by passing the tie through it.
Then, you need to thread the tie through the hole. Pay attention that the screed lock on the installed wiper is closer to the hood than to the glass. Otherwise, it can interfere with the snug fit of the wiper to the windshield and scratch it.
Pay close attention to how the screed runs. The rubber band of the wiper blade has, as it were, "gills". It was between them that I made a hole in order to preserve the cleaning properties of the wiper. Otherwise, the rubber-to-glass contact would not be tight, and the repair of the wiper blade would only give a visual effect.
Have you done it? Wonderful. Now we carefully start tightening, not forgetting to tweak the screed lock. It must be tweaked very delicately, so as not to shatter the hole in the gum.
After tightening, we saw off the dangling end with the same clerical knife.
Well, actually, that's how I ended up doing it. In my opinion, it turned out not bad. Yes, and on a car, after installation, it is not noticeable, unless of course you know and do not look closely.
Unfortunately, I forgot to take a picture of what the repaired wiper blade looks like on the car. But I will say one thing, that we got back in the rain normally. The brush retained its original function and did not scratch the glass.
I will not say that the repair of the wiper blade, which I described in this post, is ideal, but, as I wrote above, the repair was carried out in the field from improvised means. What I found, I screwed it up)))
Time spent at most 10 minutes.I strongly recommend that you use this method only in emergency situations and replace the wiper blade as soon as possible. Fortunately, the prices for them are not very high, and you can only spend money on one, and not on a set. Don't save money on your own safety.
That's probably all. All questions, additions and thoughts are left in the comments.
Operating the car in poor visibility conditions is something that vehicle drivers are constantly faced with. Depending on the weather conditions (snow, rain, etc.), the view of the space in front of the car's windshield can be significantly impaired, which contributes to the creation of an emergency on the road. At the same time, the cleanliness of the windshield, which is provided by car wipers, wipers in everyday life, is of no small importance and largely depends on the state of the latter.
Having found that when the wipers are working, there are stains on the windshield of the car, it is necessary to check their condition and determine the reasons for poor-quality glass cleaning.
Quite often, the reason for the appearance of streaks on the windshield of a car are:
oily windshield that even the best windshield wipers can't clean;
loose fit of elastic brushes to the windshield;
malfunctions of metal parts of the wiper drive;
wear of the cleaning edge of the elastic element of the brushes.
The reasons that caused the poor-quality work of the wipers may be due to:
prolonged contact of stationary brushes with the windshield of the machine (deformation of elastic parts) under the influence of direct sunlight or in severe frost;
ingress of dirt into the grooves of the elastic band of the wiper;
water getting into the grooves of the brush with its subsequent freezing;
changes in the chemical structure of elastic parts under the influence of ultraviolet radiation (direct sunlight);
wear of the working edge of the elastic band;
the appearance of traces of corrosion on the blades of the tape.
Noticing that the brushes began to clean the windshield of the car poorly, motorists, as a rule, try to replace them with new ones. However, this is not always justified, since in some cases it is not difficult to restore the performance of the wipers on the car. For example, if during the operation of the machine it was found that the working edge of the brushes is badly worn out, then you can restore its shape using sandpaper.
Take a sheet of non-bending material (multilayer plywood, a fairly thick sheet of metal, etc.).
Glue a strip of fine-grained sandpaper on it.
Carrying out the cleaning blade of the wiper over the sandpaper, they restore the shape of the tape, giving the working edge a rectangular shape.
If the elastic band of the wiper has hardened, gasoline can be used to restore it. Having dipped the tape in gasoline, it is then washed in warm water and a thin layer of silicone grease is applied to the working surface. These procedures will restore elasticity to the tape and make it softer.
The working surface of the janitor is covered with an oily film, then you can restore its properties (degrease), for example, using white spirit. White spirit will easily remove grease and other dirt from the brush surface. After this procedure, it is advisable to apply a thin layer of silicone grease to the working surface of the wiper belt. Thus, its performance will be restored. How experienced motorists restore wipers on a car can be seen on:
In the same way, it is possible to remove traces of corrosion from the working surface of the wiper.
Car wipers, like other parts of your car, require regular maintenance. In order to extend the "life" of wipers on cars, experts recommend:
regularly clean the windshield of the car and the working surfaces of the wipers from dust, dirt and fat deposits, and in the winter season from snow and ice;
remove the wipers if the car is left outside for a long time;
leaving the car in the garage, raise the wipers in such a way as to exclude contact of elastic surfaces with the windshield (the distance to the windshield must be at least 5 mm);
It is extremely important in the winter season to turn on the wiper only after the ice on the windshield of the car has melted.
wiper VAZ 2110
A windshield wiper or wipers have an important function on a vehicle. When they fail, any driver begins to feel uncomfortable, especially if he is on the road. Repair of wipers in this case will not present any problems, especially if you use the information given in this article.
The essence of how to repair wipers on a VAZ 2110 is to fix the levers or deformed wiper rods. Often the reason lies in the contamination of the parts. If it is impossible to repair the wipers, then they must be completely replaced.Often the cause of a breakdown can be a gearmotor, and if you replace the gears in it, clean the contacts of the collector or limit switch, everything will work. If the gearmotor cannot be repaired, it will have to be replaced with a new one.
All the work must be done in order and at the same time not missing anything:
remove the wiper (on the vaz 2110 it can be completely removed);
unscrew the nut securing the leash;
remove the leash itself.
removing the leash from the wiper
Go ahead and continue to repair the wipers of the VAZ 2110:
the turn of the gear motor has come (it can be wrapped in a thin leather film, which must be removed);
unscrew the three bolts of the gear motor, marked with arrows in the upper photo;
remove the black plastic cover by unscrewing two screws for this;
after removing the cover, unscrew the following screws.

We continue and by the way, you can also repair the wipers on the VAZ 2107:
take out the plate with 3 contacts located on it;
after which we remove the brown gasket;
we see the design of gears and rollers;
remove the largest gear along with the roller, revealing a plastic washer under it;
we extract two small gears, which must be noted before removal (this is done in order not to confuse their original location, because they do not have the same inclination of the teeth).
removing the gears of the wiper motor VAZ 2110
we disconnect the gearbox from the electric motor by unscrewing for this two screws located opposite;
we remove the anchor from the metal case of the electric motor;
at this stage, you should thoroughly clean all parts from dirt and old grease (we use a rag soaked in acetone).
Cleaning the wipers of the VAZ 2107, the repair of which can also be carried out according to this scheme, implies care and a detailed inspection:
we press with our fingers on three brushes in special holders (they must move freely, and if they go down tightly, then there are defects or cracks, and they must be replaced completely);
we check three springs, which should be even, without stretching and breakage.
We continue to repair the wipers of the VAZ 2107 or 2110 by inspecting the collector. For this:
we inspect it for damage, scratches or dirt;
if it is heavily soiled, it is recommended to use a fine sandpaper (if this does not give any results or it will already be seen that the collector is badly worn out, it will be necessary to replace the whole armature or the entire gearmotor as a whole);
we inspect the teeth of the gears of the gearbox and replace them if gross scratches or other defects are found;
if defects are found on the thread of the rollers of the levers or brushes, then the rods must be replaced in a complete set;
we inspect the limit switch plate and, if necessary, run it with a sandpaper and over it;
we inspect the leash mount, or rather its black rubberized cushions (if they have lost their elasticity or burst, you need to replace them with new ones - replacement is carried out by removing the inner spacer steel sleeve);
On the VAZ 2109, the repair of the wipers also takes place, that is, they start with the gear motor. So, let's continue:
we assemble the wiper, having previously well lubricated all the parts (especially you should pay attention to the gross worm of the armature and gears - use Litol-24 grease, and the marked gears should be put in place exactly);
set the anchor by tying the brushes with wire to the contacts (this stage of work is carried out in order not to curl the brushes and therefore they must be folded);
we mount the anchor in the gearbox housing very carefully;
we install the electric motor housing on the gearbox, holding the armature shaft;
we untie or bite off the wire holding the brushes and knock on the gearmotor with a wooden hammer in order to center the bearings;
we install the leash back on the axle, which must necessarily stand in a horizontal position and in proportion to the central thrust.
Attention: Before proceeding with the repair of the gearmotor, read the technical characteristics of the normal operation of this part.
shaft rotation frequency, if voltage is applied to 14 V low - thirty or forty;
the rotation speed of the shaft of a larger value - seventy;
On the VAZ 2106, the repair of wipers is carried out a little differently. Although the whole process is similar to the above instructions, there is still a difference. But consider a way to change the old wiper blade to a new one.
First, we arm ourselves with a screwdriver and start the process:
for VAZ 2106, the wiper drive rods are connected not only to each other, but also to the cranks with hinges;
remove the wiper and motor reducer;
remove the thrust hinge stopper from the groove of the crank axis;
remove it from the axis.
removing the hinge stopper from the axis
remove the thrust from the axle;
disassemble the wiper rods;
we assemble a new thrust in the reverse order with the same drive;
install the gearmotor on the bracket carefully, paying attention to the condition of the rubber bushings.
Attention: When working, you need to use a wide-blade screwdriver. It will be more convenient for her to remove and install the bushings.
The repair of the VAZ 2106 wipers continues. Now let's look at how to clean the manifold and change the gears. We carry out the following operations:
we remove the wipers, as indicated above;
we turn off the fasteners for fixing the leash;
remove it from the gear motor roller.
This video can be found on the internet. We continue:
we unscrew the gearbox mounting bolts (there should be three of them);
remove the gear motor;
we see a protective film on it, which should be removed;
remove the plastic cover by unscrewing the two fastening screws;
