The heating, ventilation and AC (HVAC) temperature control knob may be hard to turn. Mitsubishi Motors has released a service bulletin outlining the necessary repairs. Repairs involve installing a new air blend door lever and link, lubing the blend door track, and installing a filter on top of the blower motor housing to prevent entry of dirt and debris. If the temperature control assembly has been damaged it will require replacement also.
2004 Mitsubishi Lancer Problem Reports
Most Reported 2004 Mitsubishi Lancer Problem Reports
Erratic HVAC blower motor operation may be caused by a failed blower motor and/or blower motor resistor. Our technicians tell us that if the blower motor resistor fails the blower motor should be checked. If the blower motor fails its functional test in should be replaced along with the failed blower motor resistor.
A hard or no start condition with fault codes P0335 and/or P0340 stored in the powertrain control module (PCM) may be due to abnormal wear of the camshaft position sensor support. Our technicians tell us a revised sensor support is available to correct this issue.
The crankshaft position sensor may fail causing a stalling can/or no start condition. Replacing the faulty crankshaft position sensor should correct this condition.
An engine overheating condition may develop due to a failed radiator cooling fan controller. The failed controller should be replaced to correct this issue.
The Check Engine Light may illuminate with a stored code P0181. Our technicians tell us the fuel level sensor may be at fault requiring replacement.
The Check Engine Light may illuminate with a stored code P0171. Our technicians tell us this can be a result of an engine vacuum leak at one or more of the fuel injector insulators. Improved insulators are available to correct this concern.
