The system of window regulators is based on work of the electric motors established in the doorway which lift and lower glasses. The system of window regulators consists of switches, engines (regulators), glasses and connecting wires.
Regulators of glasses are connected so that glasses can be lowered or lifted by means of the main block of switches at the driver or by means of the switches located directly on doors. On each door the separate motor which can work in both directions is established, lifting and lowering glasses.
Position of the switch defines polarity and, thus, the direction of operation of the engine. On some models the relays supervising an electric current, arriving on engines of window regulators are established.
On some models the separate automatic switch for each of engines of window regulators in addition to a safety lock or the automatic switch, protecting all chain is established. It protects system from that one failed window regulator did not block work of all system.
Window regulators work only when a key in the lock of ignition will turn in the situation On. Also, at the inclusion, the blocking switch on the main block of switches can block switches on all doors of the car, including a forward door of the passenger. Always check a condition of this switch before the beginning of diagnostics of system.
Operations on diagnostics, available to the simple motorist, are very superficial, therefore if you cannot find a malfunction source, address to experts.

| PERFORMANCE ORDER
|1. If window regulators do not work, check a safety lock or the automatic switch.
| 2. If only back window regulators or if window regulators obey only the main block of switches do not work, check blocking switch of back window regulators on conductivity of a current in the switched-off situation (see tab. The table of connection of a tester and conductivity of the switch of a window regulator on a car door). Replace it if he does not carry out a current.
|3. Check wires between switches and the panel of safety locks on integrity. Restore connection if there was a gap.
| 4. If only one window regulator does not obey the main block of switches, try to lower or lift this glass by means of the switch established on a door. The exception makes a window regulator of a door of the driver.
|5. If this window regulator obeys the door switch and does not obey the main block of switches, check the switch on conductivity (see tab. Table of connection of a tester and conductivity of the main block of switches of window regulators).
|6. If the switch as it should be, check wires between this switch and the window regulator engine on existence of short circuit or a gap.
|7. If the window regulator does not obey both switches, remove the panel of furnish of a door on which this window regulator is established and check tension presence on the electric motor at turning on of the switch.
|8. If on the engine there is a tension, disconnect glass from a regulator. Lift or lower glass a hand and check, whether погнуто it or is damaged. Also, check, whether will bend or the window regulator is damaged. If the window regulator is not damaged and glass goes up and down it is easy, replace the engine. If glass or a window regulator are damaged or deformed, grease, replace or repair faulty details.
|9. If on the engine there is no tension, check wires between switches and engines on integrity. You should look at schemes of electric equipment of the car. Electric chains of some window regulators are protected by the relay. If they are available, check, that they were reliably earthed, and to them tension from switches arrived. Also, check, that each relay sent tension on the engine at turning on of the switch. If is not present, replace the relay.
|10. Check work of window regulators on termination of work.
