INSPECTION
1. A/C control panel assembly:
INSPECT DEFOGGER SWITCH OPERATION
(a) Connect the positive (+) lead from the battery to terminal
17, 18 and negative (-) lead to terminal 40.
(b) Connect the positive (+) lead from the battery to terminal
24 through a 1.4 W test bulb.
(c) Turn the defogger switch ON and check that the test bulb
and indicator light turn ON, then turn OFF after about 15
minutes.
If operation is not as specified, proceed to the next inspection.
2. INSPECT DEFOGGER RELAY CONTINUITY
