INSPECT ILLUMINATION





1. Connect the positive (+) lead from the battery to terminal C-15 and the negative (-) lead to terminal C-13.

2. Check that the illumination lights up.

If the illumination does not light up, test the bulb.

Indicators





1. Inspect air inlet indicator.
(with auto A/C)
connect the positive (+) lead from the battery to terminal A-5 and the negative (-) lead to each terminal, and check that the indicators light up as shown.
B-1 FRESH
B-5 RECIRC

If operation is not as specified, replace the A/C control assembly.





(without auto A/C)
a. Connect the positive (+) lead from the battery to terminal A-5 and the negative (-) lead to terminal C-10.
b. Check that the FRESH and RECIRC indicators light up alternately each time the air inlet control switch button is pressed.

If operation is not as specified, replace the A/C control assembly.

2. Inspect mode indicator.
a. Connect the positive (+) lead from the battery to terminal A-5 and the negative (-) lead to terminal C-10.
b. Push each of the mode buttons in and check that their indicators light up.

If operation is not as specified, replace the A/C control assembly.

NOTE: Perform the following check only for vehicles with Auto A/C.





c. Disconnect the negative (-) lead from terminal C-10. Then connect it to each terminal and check that the indicator lights up as shown.
A-8 FACE
A-9 B/L
A-24 FOOT
B-7 AUTO

If operation is not as specified, replace the A/C control assembly.





3. Inspect blower speed control.
a. Connect the positive (+) lead from the battery to terminal A-5 and the negative (-) lead to terminal C-10.
b. Push each button of the blower buttons in and check that their indicators light up.

NOTE: The indicator will not light up when the blower button is in the OFF position.

If operation is not as specified, replace the A/C control assembly.

NOTE: Perform the following check only for vehicles with Auto A/C.





c. Disconnect the negative (-) lead from terminal C-10. Then connect it to each terminal and check that the indicators light up as shown.





If operation is not as specified, replace the A/C control assembly.





4. (with A/C) Inspect A/C indicator.
a. Connect the positive (+) lead from the battery to terminal A-5 and the negative (-) lead to terminal C-11.
b. Push the A/C button in and check that the indicator lights up.
