Hi all

Yes I have trolled through threads here trying to get an answer but I could only find part answers at best .

I have very weak pressure coming out the vents, the worst area is the dash vents and they groan for a few seconds behind the head unit area when you select that setting (face setting) . Happens on both open vent and recirc mode .

Edit * also noticed the compressor is cycling every 12 seconds lasting about 10 seconds before switching off again repeats (not even a hot day )

Have done the recirc cabin filter/door check and all OK
Most of the cold air goes to the footwell no matter what setting you go to , but even that isn't at full strength when selecting feet mode alone .

I read about servo motors but I would have thought it only affects one area say driver's side and passenger side could still operate ok
