Sometimes there are questions about the analysis of the power window buttons. The case is very simple, but still it was decided to write a detailed guide for the complete disassembly of the block.
To begin with, the entire side support unit is removed. To do this, a hatch opens in the pocket (you can pry it with a flat screwdriver on the sides) and 2 bolts are unscrewed with the TORX-15 head. Then the handle goes up. It holds on to the plastic with two staples, rather weakly. And the whole block in the case is in the hands of.

We pull out the window lifter unit. To do this, we squeeze the plastic in six places (they are symmetrical on both sides) and take the block down. It is most convenient to start from the back side.

Remove the top plate. To do this, the plastic is pressed in six places (they are also symmetrical on both sides), after which the plastic is removed forward-up.

For subsequent disassembly, it is necessary to remove the window lifter and passenger window lifter lock buttons. To remove the power window buttons, you can pry them with a thin screwdriver through the side windows. The second option is simply pulling them back with your finger. In this case, you need to make a big enough effort.

These buttons are held by plastic spacers on both sides of the plastic buttons.

The window lifter lock button is removed from the latches by pressing the button legs.

The removal of the door lock is not required — it is held by the lugs on the protrusions on the block body.
Next, remove the lower plate of the block. To do this, 6 latches are pressed (symmetrical on both sides) and this plate is removed.

We have 4 power window buttons on our hands, a passenger window lock button, an upper plate, a block housing, a board with contacts and the buttons themselves, a lower plate.

The electronic parts of the buttons themselves are removed very simply, they are simply lifted from the board. If necessary, their legs can be slightly pressed from the back with a flat screwdriver — no soldering is used, only the usual tight physical contact. There are rubber mushroom contactors on the bottom, they are also simply removable.

Removed buttons with contactors​

To disassemble and clean the electronic buttons of the front windows (with Auto mode), it is necessary, using a thin flat screwdriver, to remove the white plate from the sides of the ears first, then the black one. The buttons can be cleaned with a toothbrush by pressing the button (contacts rise, the gap increases). Inside there is a special lubricant, which eventually gets clogged with dirt, worsening contact. Further disassembly is undesirable — small springs with contacts remain inside, the loss of which is very undesirable. The assembly is done in reverse order (first the black part, then the white part). There is no difference in position (top-bottom).

Disassembled button​

Sometimes it is necessary to disassemble the passenger window lifter lock button (for example, it has stopped being pressed). It is removed from the board in the same way as the buttons, being held on the board simply by the antennae. The removal of the button body is achieved by squeezing the plastic lugs on both sides.
Image

Removing the lock button​

The button consists of four parts — the upper part of the button, the outer housing, the spring, the inner housing with contacts, the switching spring.

In case of failure of the button (the button is not clamped in the pressed position), it is necessary to achieve an angle of 90 degrees in the upper part of the spring (with a long tip). Next, the reverse installation of the spring is required. To do this, the round part of the spring is put on the pin, the short tip is inserted into the hole in the inner housing with contacts, the upper tip simply remains (in the photo, for clarity, the upper part of the button is put on it in the "pressed" position).

The button assembly is simple. The main thing is not to confuse the sides of the outer case (the extension is placed on a spring).
Image

Assembling the window lifter lock button​

Complete assembly is performed in the reverse order described in Part 1. All parts of the unit should be installed easily, the latches are put on with some effort and before clicking (full installation). If necessary, you can glue some parts adjacent to each other with an "anti-scratch". Disassembly of passenger units is almost identical with differences in size and number of buttons.
This disassembly will make it possible to clean absolutely all places.
