I recently bought the subject vehicle and one of the issues was the temperature knob which is so stiff, it cannot be turned easily past the 11 o'clock position. Right now it is summer and not an issue, since it is okay in the cooler / colder area of the range, but we wil eventually want heat.

I went to the Mitsubishi dealership for this among other issues, and the advisor said that they have a TSB and a new designed blend door to resolve the issue (
