SYMPTOM TROUBLESHOOTING CHART - 04-05 MODELS

Symptom Diagnostic procedure Also check for
Engine overheats
  1. Check the coolant level.
  2. Check for coolant leakage (from gaskets, hoses, O-rings, etc.).
  3. Check for dirt, leaves, or insects on radiator and condenser.
  4. Check for deteriorated coolant.
  5. Check for damaged or deformed fan shrouds.
  6. Inspect the fan motors (see FAN MOTOR TEST ) or fan relays (see POWER RELAY TEST ).
  7. Check the radiator cap (see RADIATOR CAP TEST ).
  8. Check the thermostat (see THERMOSTAT TEST ).
  9. Inspect the water pump (see WATER PUMP INSPECTION ).
  10. Check for plugged or deteriorated radiator hoses.
  11. Check for plugged heater core or hose(s).
  12. Check for a damaged cylinder head gasket.
  
The radiator fan does not run at all Radiator fan circuit troubleshooting (see RADIATOR FAN CIRCUIT TROUBLESHOOTING  ). Cleanliness and tightness of all connectors
The radiator fan does not run for engine cooling, but it runs with the A/C on Radiator fan switch circuit troubleshooting (Open) (see RADIATOR FAN SWITCH CIRCUIT TROUBLESHOOTING (OPEN)  ). Cleanliness and tightness of all connectors
The radiator fan runs with the ignition switch ON (II), the A/C off, and the engine coolant temperature below 199°F (93°C) Radiator fan switch circuit troubleshooting (Short) (see RADIATOR FAN SWITCH CIRCUIT TROUBLESHOOTING (SHORT)  ). Cleanliness and tightness of all connectors
The A/C condenser fan does not run at all (but the radiator fan runs with the A/C on) A/C condenser fan circuit troubleshooting (see A/C CONDENSER FAN CIRCUIT TROUBLESHOOTING ).
Both the radiator fan and the A/C condenser fan do not run with the A/C on (but the A/C compressor runs with the A/C on) Radiator and A/C condenser fan common circuit troubleshooting (see RADIATOR AND A/C CONDENSER FAN COMMON CIRCUIT TROUBLESHOOTING ).

Symptom Diagnostic procedure Also check for
Engine overheats
  1. Check the coolant level.
  2. Check for coolant leakage (from gaskets, hoses, O-rings, etc.).
  3. Check for dirt, leaves, or insects oh radiator and A/C condenser.
  4. Check for deteriorated coolant.
  5. Check for damaged or deformed fan shrouds.
  6. Inspect the fan motors (see FAN MOTOR TEST ) or fan relays (see POWER RELAY TEST ).
  7. Check the radiator cap (see RADIATOR CAP TEST ).
  8. Check the thermostat (see THERMOSTAT TEST ).
  9. Inspect the water pump (see WATER PUMP INSPECTION ).
  10. Check for plugged or deteriorated radiator hoses.
  11. Check for plugged heater core or hoses.
  12. Check for a damaged cylinder head gasket.
  
The radiator fan does not run at all
  1. Check for PGM-FI DTCs (see GENERAL TROUBLESHOOTING INFORMATION ).
  2. Radiator fan circuit troubleshooting (see RADIATOR FAN CIRCUIT TROUBLESHOOTING  ).
 Cleanliness and tightness of all connectors
Both the radiator fan and the A/C condenser fan run with the ignition switch ON (II), the A/C off, and the engine coolant temperature below 199°F (93°C) Remove the radiator fan relay, and test.
  • If the relay is faulty, replace it.
  • If the relay is OK, repair a short in the wire between radiator fan relay 4P socket terminal No. 4 and ECM/PCM connector terminal E12.
 Cleanliness and tightness of all connectors
The A/C condenser fan does not run at all (but the radiator fan runs with the A/C on) A/C condenser fan circuit troubleshooting (see A/C CONDENSER FAN CIRCUIT TROUBLESHOOTING ).
Both the radiator fan and the A/C condenser fan do not run with the A/C on (but the A/C compressor runs with the A/C on) Radiator and A/C condenser fan common circuit troubleshooting (see RADIATOR AND A/C CONDENSER FAN COMMON CIRCUIT TROUBLESHOOTING ).
The A/C compressor clutch does not engage (but both the radiator fan and the A/C condenser fan run with the A/C on) A/C compressor clutch circuit troubleshooting (see A/C COMPRESSOR CLUTCH CIRCUIT TROUBLESHOOTING ).
