IDENTIFYING HAZARD WARNING SWITCH CONTINUITY

Condition	Tester Connection	Specified Condition
OFF	5 - 9	No continuity
ON	5 - 9	Continuity
Illumination circuit	4 - 6	Continuity

If the continuity is not as specified, replace the A/C control switch.

INSPECT TURN SIGNAL FLASHER CIRCUIT

Disconnect the connector from the combination switch and inspect the connector on the wire harness side, as shown in IDENTIFYING TURN SIGNAL FLASHER CIRCUIT CONTINUITY .
