This is my mothers', personally I have a Corsa :P The interior heating on my 1998 Corsa is powerful and very warm. The Astra seems very weak in comparison, even at setting 4. You can barely feel anything coming out of the windscreen vents. Is this normal? Can someone please tell me whether the force of air coming from any vents is strong. Thank you.
For the record, I can hear changes in tone as I move the vent-adjuster (so flaps seem to be working) and the fan itself sounds loud at 4.
