Mine is cyclonic!

My D2 tho .. pfft!

Could be slightly rusted up motor/bearings .. I've pulled the D2 and found it almost seized.
Used one from the spare and found it a bit better, but not much.
Lots of INOX later, and a small smear of grease .. now with two in hand:

spare uses about 20amps at full whack .. original uses just under .. like 17 or so.
So could be windings, slightly tarnished connectors .. etc.

Another thing to look into(literally) is the condition of the foam seals around the inside of the dash, that hook up the HVAC unit to the actual vents themselves.
In my D1, all were so fragile they didn't seal. Move them and they crumbled into dust. So new sealing between HVAC unit outlets and vent ducts were needed before installing the complicated dash console.
I had nothing other than lots of high density packing foam(from the likes of LCD/LED screens, and such like) .. but not styrene tho.
Made rectangles, cut out just enough of the centres to keep them tight on the vents, no leaks .. cyclonic air out the vents.

If your Disco(1 or 2) has been molested by a pack of angry gorillas like my D2 .. you may find many smashed pieces of the HVAC unit all around the rear of the dash!
That is, it wasn't just leaking seals(as you'd expect after 20 something years ... it a rabbit warren of random venting all about the rear of the dash..

Much epoxy and duct tape later .. I thought I got it right .. but compared to D1 .. I reckon another shot at checking leaks may be needed.

And the button to the left of the a/c button is the recirculation button - use air from outside the cabin for heating cooling or recirculate the air from within.
