I would check the passenger side temperature blend door damper motor and/or linkage, see if that moves while you operate the temp. knob. The blend door motor is located on the passenger side next to the heater core area: Remove the carpeted plastic next to the center console . Usually a simple calibration by a Volvo specialized shop with VIDA (Volvo's dealership scan tool) would fix this issue but sometimes the linkage breaks or the motor fails. Oh while your in there, check the cabin air filter. :-) -Sam
