My heater suddenly stopped blowing air. At first, it would still work only if you turn it on max (or to 4). Than go on and off, now its not working at all.

Welcome to the forum, I'd have to check voltage and ground at the blower motor. Could be faulty blower motor. Also, check fuse 64--30 amp in under hood fuse box. Use a testlite, the circuit goes hot when you turn on the key. The lower speeds on the blower motor, are controled on the ground circuit, through a resistor block and blower switch. Max speed doesn't use a resistor.
