5. A/C or DEF Switch:
INSPECT INDICATOR LIGHT OPERATION
(a) Connect the positive (+) lead from the battery to terminal
A−9 and the negative ( −) lead to terminal B−18.
(b) Push the A/C or DEF switch button in and check that the indicator light lights up.
(c) Then, connect the positive (+) lead from the battery to ter-
minal A−13 and check that the indicator dims.
If operation is not as specified, replace the A/C control assem-
bly.

If continuity is not as specified, replace the A/C control assem-
bly.
9. INSPECT A/C OR DEF SWITCH CONTINUITY
Check that there is continuity between terminals B− 6 and B−17
intermittently each time the A/C or DEF switch button pressed.
If continuity is not as specified, replace the A/C control assem-
bly.
10. INSPECT TEMPERATURE CONTROL SWITCH RESIS-
TANCE
(a) Measure resistance between terminals B −1 and B−2.
Standard resistance:
Approx. 3.0 kΩ
(b) Check that the resistance between terminals B −1 and
B−3 increases from 0 to approx. 3.0 k Ω when the switch
knob is turned from COOL to HOT.
If operation is not as specified, replace the A/C control assem-
bly.
