I recently changed my mk6 dash to a mk7 , I have replace the compete dash using mk7 heater ducts , all the ducts are in place and seated correctly , I have changed the cable on the heater control for a longer one but this is on the temp side , my heater blows air threw forward facing vents and also on the feet but is very poor on the window now , literally nothing coming out the top of the dash tho sounds like loud like is pushing the air up but something is blocking it ? Is there flaps inside the dash that may be stuck shut ? , as far as I can see all the wiring and ducts are fine , what has changed ?
