How does he heat the rear window?

Ratings Still rocky 25th volume rear warehouse having little interest in space technology, but its appearance on the fives and sevens in the export market screamed for the disappearance of the wild rulers of the Radyan machines. These days, only linear generators do not put heating threads on the back side, and this is no longer an option, but

standard equipment

for all cars.

How does the rear window heater work?

The heating threads are located on the rear window of the car; on some models there is local heating of the front and rear side windows.
The purpose of this device is to create a positive temperature on the surface of the glass regardless of the temperature outside.
This is to avoid tarnishing, glaring and to ensure decent visibility in all minds.
As a standard, the rear window heating system consists of several elements.
The warehouse contains the following models, or, for example, Renault Logan components:
string threads

control lamp on the control panel

a devotee at the underground block

Down button

contacts

heating relay
The principle is simple - the terminal from the wire threads on one side is connected to the on-board electrical system, on the other side it is connected to the ground.
When the stream is applied to the threads, the stink vibrates heat, warming up the entire area of the warehouse.

Typical heater failures

It is ineffective to remove everything through one thread that has burned out.

Renault services do not deal with thread repairs, but recommend replacement of parts entirely, so rational people cannot make such repairs.

The procedure for updating the heating system is not complicated, it does not take many hours, and with the right approach you can save a lot of pennies.

I'll look for the problematic thread and shave it

It’s as simple as shelling pears to understand how the thread doesn’t work - you just can’t warm up the area in your zone, and you’ll have to tinker with the designated area.

The skin thread is connected to the vertical side splints in parallel, so it can be worked independently of the suture threads.

When I managed to discover the place visually, I used the magnifying glass for help - it was miraculous.

Anyway, we need a voltmeter. On the positive bus, the voltage is 12 V, therefore, at the point of rupture, the flow through the thread is pinned, and the voltmeter will show it with an accuracy of up to a millimeter. To do this, you need to attach one voltmeter probe to the positive terminal, and with the heater turned on, run another probe along the non-working thread until the voltmeter shows no voltage.
Localization cut.
This way you can easily determine the location using a car tester or an ohmmeter. Methods for troubleshooting Do-it-yourself repair of the rear fender heating can be done in a number of ways by updating the heating thread.
Soft solder.

An affordable and reliable method for renewing frying threads.

The threads are soldered using the emergency soldering method.

However, there is one important nuance - always do not try to clean the soldering area with an emery paper.

This will increase the width of the opening.
Simply lighten the thread with acetone.

Wire-conducting pastes and adhesives are an inexpensive way to repair heating

If the width of the tear is larger per millimeter, then it is best to use a thread with tinned copper vein of 0.2 mm thickness.

For repairs, soft solder of POS-61 grade is used.

In this case, there is no need to heat the thread itself. In this way, in just 10 minutes you will solve the problem of heating the rear deck and save on the expensive replacement of the heater. Noviny

Good afternoon. Today we’ll talk about how to repair rear window heating.

It is traditional for our site to include a large number of photos and video materials and a step-by-step algorithm to detect problems.

How does heating work?
I think everyone remembers physics from high school.

When an electrical current flows through the conductor, it heats up.

This very principle is used to heat the rear window.

It is important to carefully approach the glass, on the sides you will touch the contacts and move the needle forward.

When voltage is applied to these terminals, an electric current flows through the heating threads and heats up the surface, no matter what.
Apparently, heating the glass does not work in only two cases:
faulty heating threads
there is no voltage at the terminals How to repair the heaters if one or more threads are faulty?

This malfunction looks like this:

For repairs we need:

emery paper with a number ranging from 1500 to 2500, 1 arch of any grain.

Wipe with alcohol using a cotton swab to clean the surface.

When we do this, we will clean and drank with sandpaper and lightly coat the surface.

Carefully apply electrically conductive glue to the damaged wood.

In order to apply the glue directly and not in a straight line, it is better to use electrical tape or masking tape.

As shown in the video, for example, statistics.

Apply electrically conductive glue using a pencil.

We check for drying glue, check, reconfigure, so that everything works and saves pennies….

Why don't you heat up the sun?

If heating the fire does not work, there are two options.

Because all the heating threads are faulty (it’s unlikely that on machines that run for 30-40 minutes, one or two threads heat up)... Or it’s faulty.

A person without special knowledge can verify only 3 speeches:

The meaning of these words can be read from the instructions for operating the vehicle.

If after checking the method of replacing your heaters without asking, it would be better to contact an electrician at the station.

How to repair the heating if the roof is sinking?

I don’t want to embarrass you, but after all, it’s a no-brainer!

So, if you need to apply electrically conductive glue, you will have to locally (locally) clean up the sinking.

I don’t believe that you can make a sinking piece of clothing without a damaged thread.
Anyone who has fallen into a drowning situation will have an ugly hole.
Because you need to repair one or a few threads on the glass, the sealant, unfortunately, will have to be removed.
Visnovok.
As you know, repairing heating systems is not easy, especially due to the need for proper care and attention.
Obviously, the simplest option is not to mend the threads, but to replace the warp, but if you think about it, if the buyer adds a warp of loose materials to the issue, then, at a minimum, tell you that the machine has been damaged.

That's all for today.

Find the correctness in the heating threads, vikorist and voltmeter.

For this purpose, attach one contact to the jet-conducting bus, and move the other one smoothly through the smoothie, which does not work.

Another method to check for thread breakage: turn off the heat on a sweaty surface. In this case, everything is likely to be smooth, except for the place of deterioration. This method is simpler than the previous one, but it is not accurate and does not work. Regardless of the chosen repair method, first clean the damaged area before the varnish until a metallic shine appears. It is easier to work with a bent dart.

Eat it any way you can.

Having soldering skills, solder the area with soft low-tin solder type POS-18 or POS-4-6.

Having reached the other end of the line to the positive terminal of the battery, wet the wound cloth.

Start vigorously rubbing the area of the tear with a stretch of 1-2 strokes.

When the thread is not damaged, the copper will begin to precipitate.

The flow of honey is similar to ice cream on a frosty glass.

When renewing the thread, I will start from the place where it was attached to the side thread-leading parts. This method is cheap, accessible, and is characterized by the high durability of the renovated plot. On the other hand, you can’t get enough of the trivialities. For a more immediate method of renewal, add special electrically conductive glue. When purchasing, consult the seller. To update the thread, create a stencil that is included with the product. Using a soft pencil, apply glue through a stencil onto the damaged area and dry for 10-15 minutes.

At any time, water will need a machine that works properly.

And sometimes these details are not considered so important, but because of the law of meanness, they themselves are needed in a twisted quill.

One of the inconveniences that can occur with water at high levels is damage to the rear heating system. Both wintering during cold weather and getting into rainy weather, this function of the car must be taken into account.

More advanced storage.
If visibility does not improve after heating the robot several times, then the operation is disrupted.
The reason may lie with the German contact with the circuit.

The effectiveness of the heater when it is turned on.

For this type, the indicator does not light up after pressing.

This may be due to a faulty key or a burnout.

The presence of sweating on the surface of the horizontal dark spots.

As a rule, such a malfunction can occur through cutting off the heating threads applied to the surface of the glass. More moisture-proofing of the warehouse If you want to get rid of anything, smut, do the correct repair of the heating of the rear wheel with your own hands or with the help of a mechanic.

Significant malfunctions and repairs
It is important that it is easy to identify problems with the heating system and that the skin can handle the given tasks.
Before starting work, it is recommended to tighten the threads applied to the edge to make it easier to remember if the edge is damaged.

Vypadki are caught if the tear is too big: the table is so small that it can be done quickly with one of the accessories.

You can also use a voltmeter or a multimeter.

In any case, in order to repair the threads around the rear window, you need to carefully repair the surface and identify any damage.

The neck is sleeping

effective ways looking for problems:

Method of visual diagnostics - in damaged areas, when the heating is turned on, the surface does not warm up and becomes saturated.
The balloon's polymer resin is thermally active.

Materials for repairing rear wheel heating

Work is carried out carefully when the heating system is turned on. Having identified the place of care, it is necessary to remove I'll dry up the spit

template and attach to the location you find.

The application of the polymer material is carried out using a pencil, and after drying is repeated several times.

After finishing, the stencil is removed and it is important not to turn on the heater.

If you have a viscous toothpaste, you may only need a high-power hair dryer, which will speed up the drying of the material.

The materials that are used in “folk” heating repair methods are farb (glue) and shavings, metal for soldering damaged areas.

As a rule, the farb is selected according to the color of the threads and combined with shavings, adjusting the proportions 1:1.

For the robot, you need a stencil to apply the sumish (with the device turned on).

The advantage of this repair method is the need for dry cleaning.

You can go immediately after the battle starts. For soldering, use zinc chloride. How to bring warmth to the help of glue Use water and vikorist glue frequently to repair the heating of the rear window. Glue from a Russian company

U winter period on cars where the air conditioner does not work very well, the rear window heater is a regular function.

It is not recommended to drive the car without being able to assess the situation behind, extremely hopelessly, and crash into a parking area with ice on the rear slope.

Drain some water to remove the ice, scrape it off with a scraper, and in most car models, rear window defoggers are installed to solve the problem with ice.

Heating the rear edge is a very simple device, consisting of a series of horizontal lines made of electrically conductive material, applied directly to the edge.

From the side edges of the glass to the threads, approach the vertical conductor lines, such as strings, and touch the electrically conductive material. The simple design of the rear window heating allows us to say that there are not many reasons that can lead to this going wrong.

Below we will outline the main reasons why the device may not work, as well as ways to repair the rear defroster. One of the most common problems with this component of the car is thread breakage. Thin electrically conductive threads should be sealed until they become ripped, and this will cause the rear heater to stop working. Most problem areas are diagnosed visually. If visible breaks in the rear heater threads cannot be detected, you can use diagnostic tools to look for a malfunction..

Then you need to wait until the warehouse is dry (about 30 minutes) and remove the stencil.

Below we will outline the main reasons why the device may not work, as well as ways to repair the rear defroster. If any electrical accessory on a car stops working, it is no longer necessary.

Before leaving the prisoner's hands, you can cause a quick cleaning of the struma in the on-board lance of the car or a serious malfunction.

Below we will outline the main reasons why the device may not work, as well as ways to repair the rear defroster. For now, just try changing the device and use the device in normal mode. If the problem persists and the element comes out of order again, then remove it. The rear panel heater may stop working properly due to oxidation of the contact directly glued to the panel.

To detect this malfunction, it is necessary to measure the voltage of the live wire and recontact it so that it exceeds 11 volts.

If, as a result of the oxidation, a value less than 11 Volts has been removed, it is necessary to clean the contact to remove the oxidation that has occurred. To clean the contact, you can use sandpaper with fine grains or special meal
