it seems that the vent will not change, everything come out the defrost. is this a electronic valve, i assume so. this is my parents van and i don;t drive it much, but i borrowed it one day to take my daughter to a doctors appointment and on the way home i dropped my wife and kid off at our house, i left the van run in the drive way and when i got back in it the ac was blowing out the dash vents, about 5 miles down the road it switched back to the defrost vents. do you think this a wire issue, a control issue or the servo in the valve ( still assuming it is electronic)
