Hot and cold air from heater

[thebadseed]

Hi guys.

I have a T25 1986 High top caravelle.
Since it has got colder on mornings I noticed that when I turn my heater on (only works on settings 1 and 2), hot air comes almost immediately out of the upper most vents (the de-mister vents for the windscreen and the single vents which demist the side cab windows), but on the other vents (the ones which should keep my legs warm!) it is really cold air. I am no mechanic, but is there two sets of ducts for the air to come through with it being such a huge difference in temperature?

Any advice or information would be much appreciated.
Thankyou.
Mark.

Later vans had ducting from the heater box to the vents by your knees.. otherwise they draw air directly from the outside, yours ain't late enough for that

If you meant the lower vent to your feet, then the ducting needs to be checked it may well have been put back wrongly after a removal
