I agree with RASMATAZ, it sounds like the blower motor has gone out here is a guide the help test the blower power and ground and if they are okay I would replace the blower motor which is a common problem .

Step 1 - A heater cannot operate unless the engine is full of coolant/antifreeze. If coolant level is low check the system for leaks.
