DIAGNOSTIC PROCEDURE FOR MAX HOT DOOR MOTOR CIRCUIT
NLHA0218
1
CHECK SIGNAL FOR OPEN OPERATION
1. Turn ignition switch to ON position.
2. Set temperature dial to “FULL COLD” position, and mode control dial to the “DEF (
)”, “VENT (
)” or “BI-LEVEL
(
)” position.
3. Set temperature dial to “FULL HOT” position, and mode control dial to the “FOOT (
)” or “FOOT/DEF (
)” posi-
tion. At this time, does an approx. 12 volts exist between the max hot door motor harness connector terminal 7 and the
body ground until the max hot door is fully opened?

CHECK SIGNAL FOR CLOSE OPERATION
1. Turn ignition switch to ON position.
2. Set temperature dial to “FULL HOT” position, and mode control dial to the “FOOT (
)” or “FOOT/DEF (
)” position
3. Set temperature dial to “FULL COLD” position, and the mode control dial to the “DEF (
)”, “VENT (
)” or “BI-
LEVEL (
