The heater knob won't move to heat on my 2004 Mitsubishi Lancer causing no heat to come from the heaters. This is a safety hazard because my windows ice up during winter and cannot defrost even on regular days.
I have a 2004 Mitsubishi Lancer sportback. The fan control unit is defective and recalled on other various Mitsubishi models including outlander and Lancer. However, since my model, the Lancer sportback was not listed under the recall, Mitsubishi refuses to repair/replace it.
