HVAC Temperature Knob Hard to Turn on Mitsubishi Lancer

The heating, ventilation and AC (HVAC) temperature control knob may be hard to turn. Mitsubishi Motors has released a service bulletin out 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.
