9.
MEASURE THE RESISTANCE BETWEEN GROUND AND THE EVAPORATOR TEMPERATURE SENSOR
SIGNAL CIRCUIT
Turn the ignition off.
Disconnect the A/C Heater Control Module harness connector.
Note: Check connector - Clean/repair as necessary.
Measure the resistance between ground and the Evaporator Temper-
ature Signal circuit.
Is the resistance below 1000.0 ohms?
Yes >> Repair the Evaporator Temperature Sensor Signal circuit
for a short to ground.
Perform BODY VERIFICATION TEST.
No >> Go to 10

MEASURE THE RESISTANCE FROM THE EVAPORATOR TEMPERATURE SENSOR SIGNAL CIRCUIT
TO THE SENSOR GROUND CIRCUIT
With the ignition off.
Measure the resistance from the Evaporator Temperature Sensor Sig-
nal circuit to the Sensor Ground circuit at the Evaporator Temperature
Sensor harness connector.
Is the resistance below 1000.0 ohms?
Yes >> Repair the Evaporator Temperature Sensor Signal circuit
for a short to the Sensor Ground circuit.
Perform BODY VERIFICATION TEST.
No >> Replace the A/C Heater Control Module. (Refer to 24 -
