MANUAL A/C DIAGNOSIS
2004 Mitsubishi Endeavor LS
2004 HVAC Heater Air Conditioning, Ventilation - Endeavor

INTRODUCTION TO HEATER, AIR CONDITIONING AND VENTILATION DIAGNOSISAir is drawn into the heater assembly from either the outside, or from the inside of
the passenger cabin if DEFROST, maximum cooling or RECIRCULATION are
selected. The air is then forced through the evaporator where heat is removed,
cooling and de-humidifying the air. Depending on the temperature selected, a
portion of this air is then forced through the heater core to achieve the selected
discharge temperature.
If the system does not cool properly, look for a problem with the refrigerant, blower
or air distribution systems. If the system does not heat properly, look for a problem
with the coolant, blower or air distribution systems. In either case all system fuses,
circuit breaker and relays should be checked. HEATER, AIR CONDITIONING AND VENTILATION DIAGNOSTIC TROUBLESHOOTING
