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

Check

 PERFORMANCE ORDER

1. Check a condition of safety locks and all terminal connections of the corresponding electric chain. Make sure of completeness of a charge of the battery.
2. Transfer transmission to situation "P", cock the parking brake and turn the ignition key in position of ON, without starting the engine.

3. Without disconnecting a heater fan electric motor, connect a wire crossing point to the plug of a blue-black wire from a reverse side of the socket of the motor (see an accompanying illustration), ground the opposite end of a wire on weight. If the motor starts working, therefore the cause of failure lies in malfunction of the switch, resistors or a connecting electrical wiring.

4. If the motor does not function at the grounded plug of a blue-black wire, remove a wire crossing point, disunite the socket and by means of the voltmeter measure tension between the plug of a blue-black wire and weight (see an illustration above). On all models if the voltmeter fixes battery tension, and the motor does not function, in one of the high-speed modes, make its replacement (see Removal and installation of an electric motor of the drive of the fan of a heater). If tension is absent, check a condition of the relay of the motor and a connecting electrical wiring (see the Head Onboard electric equipment).

5. Resistor assembly is located on a casing of a driving electric motor of the fan (see an accompanying illustration). On a payment several resistors which provide a possibility of the choice of the low and average high-speed modes of functioning of the fan are installed to assembly.

6. If the motor rotates, however there is no possibility of the choice of one of the high-speed modes, remove resistor assembly from a casing of a heater and visually check it for existence of damages. by means of an ohmmeter check resistance between plugs 2 and 4 (see an accompanying illustration). If resistance any of resistors is shown below norm, or is equal to infinity, replace assembly.

Replacement

 PERFORMANCE ORDER

1. Turn out two fixing screws and remove a payment of resistor assembly from a heater casing.
2. Installation is made upside-down.
