A/C Auto Amp Power and Ground Diagnosis Procedure
INFOID:0000000001547370
DIAGNOSTIC PROCEDURE FOR A/C SYSTEM
SYMPTOM: A/C system does not come on.
1.CHECK POWER SUPPLY CIRCUIT FOR FRONT AIR CONTROL.
1. Turn ignition switch OFF.
2. Disconnect front air control connector.
3. Check voltage between front air control harness connector and
ground.
OK or NG
OK >> GO TO 2.
NG >> Check 10A fuses Nos. 2, 13 and 16, located in the fuse block (J/B).
 If fuses are OK, check harness for open circuit. Repair or replace if necessary.
 If fuses are NG, replace fuse and check harness for short circuit. Repair or replace if necessary.
