    Dismantle the krivoshipny handle of a window regulator: from an axis of the krivoshipny handle insert under it a screw-driver and press a fixing uvula. Remove a covering to a handle axis. Under it unscrew the screw with a crosswise head. Remove down a bowl of the internal handle of a door after weakening of the screw with a crosswise head. Behind the handle there are available two other screws with crosswise heads. Unscrew them. On the front party of facing ahead and behind unscrew on one screw with crosswise heads. The button of internal blocking of a door remains mounted. Now with fist blows from below on an armrest slightly line door facing up in order that clamps on a reverse side of facing left grooves of a door box. Remove facing and cast away from a door a little. On a reverse side of disconnecting contact of a door take out a cable cover from directing and hang out a cable. Disconnect shtekerny sockets on switches and on dynamics. If it is necessary, carefully remove an insulating film behind on door facing. Track that it did not tear in places of clamps and contacts of switches. Before installation of facing insert intermediate rubber details into openings of clamps in a door box (if they departed at dismantle). In order that clamps moved better, grease rubber details with a small amount of vaseline or silicone paste. Track that the insulating film was carefully inserted on a reverse side of facing. It should be inserted into deepening on facing perimeter. At installation pay attention to that the button of blocking of a door was correctly inserted into an opening in facing.

Detachment of details of a door

For example, after a small damage of metal it can appear necessary to remove a door basis from a support of its assembly knots. In this case it is recommended to varnish a new basis of a door before installation. Though after that it is necessary to work very carefully.


    Dismantle door facing. Dismantle a door how it is described above, and put outer side on a soft lining (polyfoam, a woolen blanket). Take out from fixing clips of a bar of management of the external handle of a door and a lock drum. For this purpose cast away on clips on 90 ° a lock latch. Weaken four fixing screws on the front parties of a door. Remove a support of assembly knots of a door up.

Dismantling of the external handle of a door

1–a lock drum with a heating element;
2–door handle;
3–rotary latch;

4–decorative panel;
5–fixing bolt of TORX ahead.
The arrow showed a spring clip of an operating bar of disconnecting contact.

Operating bar of the lock with the following details

1–lever of a drum of the lock;
2–spring clip;

4–an operating spring clip;
5–the switching-off lever of the lock.

The window regulator is visible from the back party on functional model:

1–the top directing roller;
2–the directing tire of a window regulator;
3–the support flew down;

4–window regulator engine.
Shooters – screw connections of a glass/window regulator.

In the photo screws (1 and 2) which should be weakened for a detachment of both parts of a door are shown.

The lock of a door hangs only on two screws (1 and 2). But at preliminary works on lock dismantle considerable volume since it is necessary to dismantle «a support of assembly knots» from a door basis.

Dismantle of the external handle of a door: besides other, it is necessary to cast away a rotary latch (1) and to unscrew TORX (2) bolt.

In drawing screw connection (2) window regulators with window (1) glass behind in a box of a forward door is shown.

Dismantle of the door lock


    Remove a support of assembly knots of a door from its basis how it is described above. Unscrew two bolts of TORX on 6 mm. Remove the lock.

 Councils: In a small series door locks were established without a synthetic covering. These locks are dismantled without removal of «a support of assembly knots» from a door.

At installation of a new operating bar between the cylinder of the lock and the lock of a door it is necessary to adjust its length. The length can be regulated by moving back the including plug on a hinge detail from the lock of an operating bar. Then the including plug again moves forward therefore the bar is fixed.

Dismantle of the external handle of a door

The one who performs this work on the mounted door, should possess quiet character and dexterous hands.


    Forward door: dismantle internal facing of a door. Cast away aside spring clips of both managing directors of bars (they conduct to a key wedge), hang out operating bars. Through dredging on inside of a door unscrew ahead on the door handle TORX bolt key Т25. Through a box of a door grope at height of a drum of the lock the small blocking lever and cast away it on 65 ° to back edge of a door. Now remove the door handle inside. Remove outside a drum of the lock and the external decorative panel. Thus slightly turn the panel. If it is necessary, disconnect a wire. Installation: it is necessary to understand an arrangement of details on the relation to each other in the dismantled condition. Otherwise with guarantee it will not be possible to establish deblocking lever. The lever of a deblokirovka is inserted by the handle inclined back and leans back forward for fixing. Handle of a back door: dismantle and installation are similar, but fastening by two TORX screws – without the deblokirovka lever.

Dismantle of a drum of the lock


    Dismantle the external handle of a door. Insert a key into a drum in order that at a pulling of a drum lock and spring plates did not drop out.

The window regulator and the mechanism of the krivoshipny handle represent the module and can be dismantled or replaced only together. Not so business is with the window regulator electric motor. It it is possible to replace separately (head Tools and devices). Installation: rivet a window regulator, thus in the beginning put the bottom rivets. Adjust a window at doors.

Window dismantle at doors

Window dismantle at doors is described above. Besides, after installation adjust glass at doors (the following section).

Window adjustment at doors

Window adjustment in a forward door: the back edge of a window (1) forward door should enters into a sealant (4) support of assembly knots of a door (2), and = 9 mm. Figure «3» designated a back rack of a door. The same treats a first line of a window of a back door.

Adjustment of glasses in lobbies and back doors is carried out equally (in a specular reflection).


    Glass in a forward door should enter the back edge (a rack In) into a sealant approximately on 9 mm. The same treats glass in a back door that for a forward door. Above and ahead glass should be parallel to a sealant on all perimeter. In other words: it should not be warped in a doorway. If it is necessary, carry out a felt-tip pen the line on back edge of a windshield (or on a first line of back glass) at distance to 9 mm from glass edge. Establish glass – watch parallelism of the line of a rubber sealant. Lift glass almost against the stop. Now check, whether the contour of a sealant and a glass contour are parallel on the relation to each other. If is not present, weaken fastening of glass and adjust glass so that it became parallel to a sealant.
