2004 Mitsubishi Lancer ProblemsSticky Temperature Knob
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.
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.

2004 Mitsubishi Lancer RecallsFront Passenger Air Bag Defect

Moisture sensitive airbag system components may deteriorate in humid climate regions, causing an increase in inflator pressure which ruptures when passenger airbags are deployed. Injury can result from inflator parts striking an occupant. Dealers will replace affected airbag inflators to correct this concern. This recall supersedes recall 14V-421.
When deployed by a crash, the passenger front air bag may come out with too much force, causing the inflator to rupture. This can result in metal debris striking occupants. Dealers will replace the passenger side air bag inflator free of charge to resolve the problem.
