Had the same problem a while back.Behind the glove box you'll see the two units with moving/joining levers.On mine one of them had come away,It took a bit of time but found the 'arm' that was causing the issue then re-attached it,no probs since.Just test it before putting glove box etc back in. Also I reckon spinning the air controller/temp dials very fast is what caused the 'arm' to pop off in the first place
Goodluck with it
