A/C Blower Resistor
1. Remove the inner roof.
2. Disconnect the
4P connector (1) for A/C blower resistor (2).
3. Measure the resistance with an ohmmeter across the R1
terminal and E terminal, and across the R2 terminal and E
terminal.
4. If the factory specifications are not indicated, A/C blower
resistor is faulty.

A/C Switch
1. Remove the inner roof, and disconnect the A/C switch
connector (2).
2. Perform the following checkings 1) and 2) .

1) Connector Voltage
1. Turn the main switch ON .
2. Measure the voltage with a voltmeter across the connector 7
terminal and 6 terminal.
3. If the voltage differs from the battery voltage, the wiring harness,
A/C relay or fuse is faulty.
2) A/C Switch
1. Check the continuity through the switch with an ohmmeter.
2. If the continuity specified below is not indicated, the switch is
faulty.
*Push the A/C switch button to ON position.
**Push again the A/C switch button to OFF position.
