Heater settings 1, 2, 3 do not work, only works on 4, but air coming through is only warm.

Is that the blower fan settings?
Are you running without a thermostat? that would explain the warm air. As far as the settings 1, 2, and 3 go if the blower fan has a resistor for anything except high, than it may be bad or maybe simply a fuse is blown. I will try to find a wiring diagram for that.
No wiring diagrams, the closest thing I could find is an owners manual for a 2006 and on page 261 it has the fuse locations. http://www.vauxhall.co.uk/content/dam/Vauxhall/Europe/united_kingdom/nscwebsite/uk/00_Home/Owner_Services/owners_manuals/astra/AstraOwnersManual_Jan06.pdf
