Hi,
Now that my EAS is working fine again (eternal thanks to Richard) on to the next problem.
There is no air coming from the vents at the windscreen (just very little in the middle).
Flap motor seems to work (replaced 2 years ago), because when I select up/down/facia the air flow does change. When I select up I can feel a little coming from the mioddle vents, but not much. When I select down it stops coming out the top vents, so flaps should be working. I believe that if the flap would be stuck the motor would go to fault and stop wiorking for a while.
I do have the book symbol on the HEVAC, but not always, but since my Nanocom broke I can´t read the faults. Could also be because the AC is not filled and/or the compressor is not engaging.
Could it be that the vent ducts to the top have somehow dislodged ? Is there a way to access them without dismantling the glove box, etc.? Would removing the instrument panel give me access ?
Thanks for any ideas or hints....
Press the Prog button and see if it is the same, if it is then it will be either the distribution blend motor (top one on the right hand side), or the linkage has jumped a tooth. Distribution motor drives 3 levers and they need to be set correctly. Top ducts have a couple of sliding joins in them and they can come apart so the air just blows around behind the dash rather than out of the vents. Driver's side can be accessed by taking the instrument cluster out (do NOT turn the ignition on with the cluster unplugged), passenger side needs the glovebox out.
OK, thanks. on PROG I can sense a small amount of warm air coming from the middle windscreen vents, so I will have a look behind the instrument cluster, but I guess it´s more likely something with the blend motor since both side vents aren´t working....

Just saw this picture, here it looks as if there are no sliding joints on the windscreen vent distribution....so it must be the blend motor....??
You're right, the sliding joints are on the ducts between bowers and matrix and matrix to end vents. You won't see anything behind the instrument cluster as your car is LHD and the linkage is on the RHS of the heater matrix. The distribution motor drives a large quadrant but there is also a lever that goes forward towards the bulkhead and I think it is that one that deals with the flaps to the windscreen vents. It runs in a slot on the back of the quadrant but can come out if it gets stiff. Or the distribution motor isn't doing anything and that is why you have the book showing. With the glovebox out (and maybe also the passenger airbag), you'll be able to operate the buttons to change where the air is supposed to go and see if the top blend motor moves.
