Check of serviceability of functioning of the driving electromotor of the fan of a heater and condition of components of its electric chain

Cars considered in the real Management are equipped with system of additional safety of SRS which is better known as a safety cushion. Before performing any works near assembly of a pillow or a steering column, without fail disconnect system in order to avoid receiving traumas as a result of its casual operation, - disconnect from the battery at first negative, then for a positive wire and wait not less than two minutes before starting service of the components located near sensors of directed overloads (see. Head Onboard electric equipment). Isolation and contact sockets of electroconducting of a chain of SRS are painted in bright yellow color. It is not necessary to connect any diagnostic devices to this chain!

Materials of this Section belong only to hand-operated models functioning of a heater and the air conditioner. In default the fan on the models equipped with system of climate control, the car follows for diagnostics and regenerative repair of the corresponding components to drive away on car repair shop.


 PERFORMANCE ORDER

1. At refusal or violation of serviceability of functioning of the fan of a heater first of all check a condition and reliability of fastening of all terminal connections of the corresponding electric chain. Make sure of completeness of a charge of the battery. Estimate a condition of the corresponding safety lock, the relay, the switch. The probability of failure of the driving electromotor is not excluded also.
2. Before starting check actually the electromotor surely estimate a safety lock and relay condition (if that is provided) (see. Head Onboard electric equipment).
3. For the purpose of ensuring access to a casing of a heater and ventilyatorny assembly remove a ware box and the bottom section of furnish of the dashboard (see. Head Body).

4. Turn the ignition key in the situation ON and transfer the switch of management of the heater fan to otkazny situation (I). Check of serviceability of giving of a food on the electromotor needs a lamp sampler or the voltmeter. If tension moves regularly, it is necessary to check a condition of a chain of grounding of the motor (on considered models the switch of management and rezistorny assembly are a part of a grounding chain). The probability of jamming of a krylchatka is not excluded also.

5. For quality check of grounding disconnect from the electromotor electroconducting and connect a wire crossing point between the plug of grounding of the motor and reliable weight. The second wire crossing point connect positive plugs of the motor and the battery. If the fan starts to rotate regularly, follows violation of quality of grounding takes place, or rezistorny assembly failed. Otherwise it is necessary to replace the motor, or to eliminate the reason of jamming of a krylchatka.
6. For identification of the reasons of jamming of a krylchatka remove electromotor assembly (see. Section Removal and installation of the electromotor of a drive of the fan of a heater).

7. At violation of quality of grounding check serviceability of a condition of the rezistorny assembly located in a casing in the neighbourhood with the electromotor.

8. By means of an ohmmeter check quality of grounding of rezistorny assembly in various positions of the switch of management, - in each of provisions (except OFF) conductivity should take place between three plugs from six.
9. In case of identification of violations it is necessary to make the corresponding regenerative repair of the switch or electroconducting of a chain going to it.
10. If grounding is serviceable, check rezistorny assembly on conductivity existence between plugs. in case of identification of break replace the resistor.
11. The description of procedures of check of functioning of a pereklchyuatel of a choice of high-speed modes of the fan see in the Section Removal and installation of assembly of the control panel by functioning of a heater and the air conditioner, adjustment of a driving cable. For the purpose of ensuring access take the control panel functioning of the heater/conditioner of air from "Torpedo".
12. Disconnect electroconducting and by means of an ohmmeter check correctness of distribution of conductivity between plugs of the socket of a pereklchyuatel.

13. In case of identification of violations replace the switch.
