Heating gone cold (always)?

I got a L plate Rover 620i back in April, at that time, the heating in the car worked ok, took a while to get warm, but worked eventually. Now, coming back into winter, the blower only blows out cold air, permenantly. Everything appears to work, u can hear a noise when changing the temperature dial, I know very little about cars, but it's in such a state it's not worth getting done professionally. Any help would be much appreciated.

take off both heater pipes and if you can get your hands on a water filled fire extinusher push one of the pipes from the heater on to the ens of the fire extinusher and give it a blast make shour the heater is in the hot poshion first if water comes gushing out the other pipe its ok if not its blocked up
i did this to one of my old cars i had and it did the trick fine and boy was my heater hot after that,

Check the water levels in the radiator, I know it sounds basic, but hell, I missed it!

check the pipes to see if their is an electric valve involved
