I have a 2006 WK Limited with dual control Heat A/C. When I need A/C, the passenger side gets ambient air while the driver's side gets cooled air. Air is correctly directed but has no A/C on passenger side. I searched and found the blend door problems in the WJ (I own one of those as well) but nothing on the WK. I also found the calibration procedure (Thanks Brianc500
) but it didn't work. Is there a calibration procedure for the 2006? How do I know if it is a blend door problem or a control problem?
