The grinding noise is from bad motor gears. They wear over time and begin to slip. Once this happens the position sensor in the motor gets out of sync and the lights do strange things. In your case, they show partially open so the original delay that occurred when you set the alarm is no longer active, so they rotate up. If both motors grind, you need both.
