I assume you've tried turning the knob?

On mine anyways there is no "all the way up" position. When you turn it one way the light goes up (clockwise), other way it goes down (counterclockwise), but the knob never hits a physical limit.

Could be a sign your battery is going bad. The car is lowering the speed to conserve battery power. At least that is what my car did. Another sign was that the welcome lights stopped coming on when I turned off the alarm. Then the battery drain light started coming on. The new battery corrected everything.
