The electric drive стеклоподъемников – the general data and check of serviceability of functioning

The control system of functioning стеклоподъемников consists of management switches, the relay, приводных electromotors, regulators стеклоподъемников, mechanisms of lowering-podnimanija of glasses and connecting electroconducting. Drive electromotors стеклоподъемников are located in door assemblages of the car.

Management стеклоподъемниками can be carried out from a driver's place by means of the main switch, or by means of manipulations with individual door switches. Each of glasses is equipped separate приводным by the electromotor of reversive type. Command key switching polarity of connection of the motor and, as consequence, a direction of its rotation changes.

The contour is protected by a safety lock and the chain breaker. The individual defence of each of electromotors is provided by own breaker of the chain preventing possibility of a conclusion out of operation of all system at jamming of separate glass also.

The electric drive стеклоподъемников functions only at the included ignition. In addition, on many models blocking possibility стеклоподъемников back (and sometimes and a lobby passenger) doors from the main switch is provided. Do not forget about the given function at check of refusals of the electric drive.

Described checks have the most general character, therefore if their performance does not allow to reveal unequivocally a cause of a failure, drive away the car for more detailed diagnostics on a car repair shop.

PERFORMANCE ORDER

1. In default стеклоподъемников always first of all check a condition of a corresponding safety lock and-or the chain breaker. If стеклоподъемники back doors cope only from the main switch, check up conductivity of the blocking switch in the released condition. The faulty switch replace.
2. Check up an electroconducting condition on a chain site between switches and the assembly block of safety locks. Make necessary repair.
3. At refusal of functioning of the main switch only one of glasses, check up serviceability of operation given стеклоподъемника from the individual switch.

The told does not concern to стеклоподъемнику a driver's door.

4. If стеклоподъемник works only from one of two switches, check up serviceability of functioning of the suspected switch (distribution проводимостей).
5. The faulty switch () is subject to replacement. If the switch is perfectly in order, check up on breakage and short circuit a chain on a site between the corresponding switch and приводным the electromotor given стеклоподъемника.
6. If стеклоподъемник does not work from both switches, remove the panel of an internal upholstery from the given door and check up serviceability of giving of a food both on the switch, and on приводной the regulator motor (at corresponding position of the switch).
7. At serviceable giving of a food on the electromotor separate glass from a regulator стеклоподъемника (the Body see the Head) and manually move it upwards-downwards, checking moving freedom. Also check up serviceability of a condition of a regulator. If the regulator in norm, and glass freely moves in both directions, replace приводной the electromotor. At infringement of smoothness of movement of components eliminate the found out hindrances, grease rubbing knots and replace the damaged details.
8. If a food on the motor does not move, check up on presence of conductivity electroconducting on a chain site between switches and motors (in case of need address to schemes of electric connections in the end of the present Chapter). If the contour is equipped by the executive relay, check up serviceability запитывания and grounding of the last. Make sure that the relay regularly gives out pressure on the included electromotor, in case of need replace the relay.
9. Having made necessary corrections, repeat functioning check стеклоподъемников.
