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.Google+

I bought the vehicle used and the knob broke on me. The temp knob has broken and I have to us pliars to move it and I still cannot get it to go to the far side on the heater. The second knob is just stuck on the front air vent and I can't move it to the floor or the dash. I have talked to two other 03 lancer es owners with the same problem. Why can't Mitsubishi fix this instead. This problem is clearly from their end .

I bough brand new lancer on 2003, after two years my wife was complain temperature knob was hard to turn. I took it to dealership in winnipeg, they said nothing wrong with it. They just spray wd44 on it, but wd44 build up more dirts. As I tried to change temperature the knob broke off, warrentee is over and dealer wanted $600.00. Plus amount other problems that I had complain before the warrentee it over. But deal consistanly brush off denied the problems. Original from Winnipeg Mitsubishi dealer, so I such up and move on. But I urge people that I knew not to buy Mitsubishi.
The temperature knob tends to get stuck if I don't move it around occasionally, so to keep it from getting stuck I have to move it back and forth everyday.
The temperature control knob shaft broke because the door to operate the temperature gets stuck. We ordered the parts from the dealer and got all the wrong stuff. Looking into how to repair. Need Help

All the knobs for the airconditioning have cracked because it was too hard to turn.
