It may have happened once or twice before but today it did it a few times.
I have the AC on full and recirc. The fan will shift from blowing out the vents to blowing out the defroster. The air is still cold. I tried a few other blend positions and the same thing happens, it goes to blowing out the defroster, stays there for a minute or so and then goes back to the desired setting.
Is the door vacuum controlled or electronic controlled?
I tried 'making it happen' by stomping on the gas but it had no effect. On my old cars, when I have this issue, the lack of vacuum at full throttle causes a similar behaviour.
Thanks!
