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

 PERFORMANCE ORDER

1. Check a condition of all terminal connections of the corresponding electric chain. Make sure of completeness of a charge of the battery. Check a safety lock No. 56 in the assembly block of safety locks/relay located in an impellent compartment, and also a safety lock No. 3 in the assembly block located at the left under the dashboard.
2. Find the relay of the electromotor of a drive of the fan of a heater in the assembly block in an impellent compartment of the car. Take this relay and check serviceability of its functioning (see. Head Onboard electric equipment). The faulty relay replace.
3. Transfer transmission to the situation "R", cock the parking brake and turn the ignition key in the situation ON, without starting the engine.

4. Assembly of the fan of a heater is located under the car dashboard, behind a ware box, near a partition of an impellent compartment.

5. Transfer the handle of management of the direction of supply of air to control panels heater functioning in the situation FLOOR (PAUL), the handle of a choice of a high-speed mode of functioning of the fan establish in situation 4. try to define aurally, whether supply of air on air lines is carried out. If air moves, transfer the handle of high-speed modes to situation 1 and again listen. Repeat check in each of positions of the handle.

The switch of high-speed modes of the fan is switched on in an electric chain of the electromotor from weight.

6. If the fan does not function, and all safety locks and the relay are checked and are in good repair, it is necessary to pass to check actually the electromotor. Find the electric socket from the back party of ventilyatorny assembly and sharp shchupy the voltmeter probe the plug of a yellow-black wire at the included ignition. On this plug tension at least 10 In should take place at any of positions of the switch of high-speed modes, except the situation OFF (Vykl), otherwise takes place chain damage on a site between the assembly block of safety locks and the control panel functioning of the heater/conditioner of air, or between the control panel and the electromotor.

7. If tension on feeding a food is present, however the fan does not function, close on mass of the chassis the plug of a blue-red wire (use a wire crossing point with sharp shchupy). If the fan when grounding the plug does not work, replace the electromotor of its drive, otherwise it is necessary to check a chain condition on a site between the switch of a choice of high-speed modes and rezistorny assembly.

8. If the fan works only in some of high-speed modes, check its resistor. Rezistorny assembly is fixed on a fan casing on the right under the dashboard. On a payment three resistors, providing possibility of functioning of the fan in three bottom various high-speed modes are placed, at turning on of the fan for the maximum speed (situation 4) the current is passed devices round of resistors.
9. Remove rezistorny assembly and visually estimate a condition of its elements (elements should not be melted off). Measure resistance between plugs 1 and 5 of the contact socket. if the result of measurement falls outside the limits a range of 5 ÷ 3.5 Ohm, replace assembly.

10. If rezistorny assembly as it should be, however the fan still functions not on all speeds, it is necessary to address to Section materials Onboard electric equipment and to remove the control panel functioning of the heater/conditioner of air. Disconnect the electroconducting socket from the back party of the switch of a choice of high-speed modes of the fan and check distribution of existence of provodimost between contact plugs in various positions of the switch. The faulty switch is subject to replacement.

 

11. Check a condition of the relay of the fan of a heater in the assembly block in an impellent compartment of the car. Take the relay from the nest and make check of serviceability of its functioning (see. Head Onboard electric equipment). Probe the voltmeter contact plugs in a nest of the assembly block: on the plug 4 tension of the battery should be present constantly, on the plug 1, - only at the included ignition. The plug 2 should be constantly earthed on weight.
