How can i fix the car heater ?

sounds like a resistor, try under the glove box in passenger footwell, adj centre console. remove a small black screw and you'll see a large resistor with a 4 wire plug connection. check the state of the connection, its prob melted so you'd need to replace it, a scrapyard will sell you a resistor for around 15-20 quid.

The heater fan will be the resistor pack burnt out! it's behind the sidetrim in the passenger footwell, £20 from ebay, as to the Heated rear window, Fuse, Relay, switch, contacts on the bootlid, or the tags on the windscreen fallen off (my mk4 had the tag on the earth side of the heater come away )
