Blower motor and resistor

- removal and refitting

1 The blower unit is located in the passenger compartment above the left-hand front footwell. If the blower doesn't work, check the fuse and all connections in the circuit for looseness and corrosion. Make sure the battery is fully-charged.

2 Remove the glovebox (see Chapter 11,

Section 27).

3 Disconnect the electrical connector from the blower motor resistor. Remove the screws and withdraw the resistor from the housing

(see illustration).

Note:The following procedures only applyto the 1.3 and 1.6 litre Non-VVT-i engines. On

VVT-i engines have the engine management ECM self-diagnosis system interrogated by a suitably-equipped repair workshop. The vehicle's diagnostic connector is located under the right-hand side of the facia.

6 Drain the coolant (see Chapter 1).

7 Disconnect the wiring connector from the sender unit (see illustrations). On 4A-FE engines, the sender is located on the rear of the engine (see illustration 7.10)

8 Using a deep socket or a spanner, remove the sender unit.

4 Using a continuity tester on the blower motor resistor, there should be continuity between all terminals. If not, renew the resistor.

5 If the blower motor must be renewed,

Disconnect the wiring plug, then remove the three mounting screws and lower the blower assembly from the housing (see illustrations). The fan can be removed and re-used on the new blower motor.

9.3 Undo the blower motor resistor 9.5a Undo the three retaining screws 9.5b. . .and lower the blower motor from
retaining screws (arrowed) (arrowed)... position

3•8 Cooling, heating and air conditioning systems

10.4a If available, use clamps on the heater hoses. . .

    Worldwide Supply and Renewal. The world's fixed supply of water in all forms (vapor, liquid, and solid) is enormous. If we could distribute it equally, there would be enough to provide every person on earth with 292 trillion liters (77 trillion gallons). However, only about 0.003% of the world's water supply is avail­able as fresh water for human use, and this supply is unevenly distributed. About 97% of the earth's total supply of water is found in the oceans and is too salty for drinking,... [читать подробенее]
