Control Assembly: Testing and Inspection
INSPECTIONCOMBINATION SWITCH ASSEMBLY
Standard Resistance:
a. Inspect blower switch.
1 Measure the resistance according to the value(s) in the table.
If the resistance is not as specified, replace the combination switch assembly.
b. Inspect illumination operation.
1 Connect the positive (+) lead from the battery to terminal 8 and the negative (-) lead to terminal 3, then check that the illuminations light up.
If the bulb does not light up, replace the bulb.
c. Inspect A/C switch.
Standard Resistance:
1 Measure the resistance according to the value(s) in the table.
If the resistance is not as specified, replace the combination switch assembly.
d. Inspect indicator operation.
1 Connect the positive (+) lead from the battery to terminal 2 and the negative (-) lead to terminal 4 while the A/C switch is pressed, then check that the indicator lights up.
If operation is not as specified, replace the combination switch assembly.
e. Inspect R/F switch.
Standard Resistance:
1 Measure the resistance according to the value(s) in the table below.
If the resistance is not as specified, replace the combination switch assembly.
f. Inspect indicator operation.
1 Connect the positive (+) lead from the battery to terminal 9 and the negative (-) lead to terminal 8 while the RIF switch is pressed, then check that the indicator lights up.
If operation is not as specified, replace the combination switch assembly.
g. Inspect illumination operation.
1 Connect the positive (+) lead from the battery to terminal 10 and the negative (-) lead to terminal 5, then check that the illuminations light up.
If the bulb does not light up, replace the bulb.
h. Inspect defroster mode detection switch.
Standard Resistance:
1 Measure the resistance according to the value(s) in the table below.
If the resistance is not as specified, replace the combination switch assembly.
