A good point. In my case, the rotary dial turned backwards as I released it, not staying at full cold. Conversely, in winter, it had no trouble effortlessly rotating to the full hot position, at 3-red-dots.

That's why I decided to force the cable to advance to 3-blue-dots, and jammed it in that position, to either stretch it back to normal length (if it had somehow become tangled?), or back into position (if it had come off-track?); it now turns in either direction more easily, and remains where I position it. I probably shouldn't have chanced breaking or stretching the cable, but I got aggravated on the 50F+ air coming out of the vents (I knew it was fully charged just before I took possession of the X5).

freedo- have you tried all adjustments, as shown in the user's manual? and tried all heater controls, too? Something may be stuck.
