The A/C and heater will blow out the defrost vent regardless of what I set for it to blow out of and automatically alternates to blowing out the main vents and it continuously alternates between the vents, swapping about every 10-20 seconds. The only exception is that about every 2-3 weeks It will only blow out the main vents but only blows at about 1/4 of the max regardless of how high or low I set it to blow, then after about 2-3 days it goes back to alternating between vents.
