DAS for the duo-valve
Are there any adaption/calibration options for the Duo-valve or manual A/C thermostat knobs in your car? I've noticed, with equal settings left vs. right, a slight temperature difference left vs. right -- in both heating and cooling (the right side is always a few degrees colder and it's noticeable to the touch).
I'm wondering if the valve has gone bad on one side, or if the valve and/or knobs just need adaption/calibration. I'm also wondering if I replace the valve will I need to adapt/calibrate it as a matter of course.
Thanks in Advance!
