2 Turn the ignition off.
Disconnect the A/C - Heater Control Module C1 harness connector.
Measure the resistance between the Evaporator Temperature Sensor Signal circuit
and the Sensor Ground circuit. The approximate circuit resistance should be:
5,900 ohms @ 38°C (100°F).
6,600 ohms @ 35°C (95°F).
7,400 ohms @ 32°C (90°F).
8,300 ohms @ 29°C (85°F).
9,400 ohms @ 27°C (80°F).
10,600 ohms @ 24°C (75°F).
11,900 ohms @ 21°C (70°F).
13,500 ohms @ 18°C (65°F).
15,300 ohms @ 16°C (60°F).
17,500 ohms @ 13°C (55°F).
19,900 ohms @ 10°C (50°F).
22,800 ohms @ 7°C (45°F).
26,100 ohms @ 4°C (40°F).
30,000 ohms @ 2°C (35°F).
34,600 ohms @ -1°C (30°F).
Is the resistance within the specifications?
Yes → Replace the A/C - Heater Control Module in accordance with the
→ Go To 3
No
3 Turn the ignition off.
Disconnect the A/C - Heater Control Module C1 harness connector.
Open the glove box door. Disconnect the glove box door roller latch from each side of
the glove box. Roll the glove box downward toward the floor.
Disconnect the in-line C202 harness connector.
Measure the resistance of the Evaporator Temperature Sensor Signal circuit between
the A/C - Heater Control Module C1 harness connector and the in-line C202 harness
connector.
Is the resistance below 5.0 ohms?
Yes → Go To 4
→ Repair the Evaporator Temperature Sensor Signal circuit be-
