Hey dudes,

Have a T4 that is blowing hot air from side and lower vents, even when dial turned to cold. From looking at other threads this is a common issue. However the ball-valve mechanism seems to be working fine (have taken off hose and checked it is opening and closing when dial in cab is turned), which seems to be the only suggestion/remedy in other threads.

Any other reasons this may be happening? About to hit Summer here in Australia, not that keen for any additional heat while driving! Am happy to adjust to cold air only too - not that bothered about being able to alternate.

Incidentally, had the same problem in T3, however was simply a bent metal rod behind slider.

Any help much appreciated!
