If the blower motor does not function, it is blown fuse, defective blower motor, defective blower motor resistor pack, or in rare instances a defective blower motor speed control switch. Check the fuse. If it is OK, apply 12 volts directly to the blower motor and if it runs, you probably have a defective Resistor Pack. Very common problem. The only fix is to replace it.
If you are talking about the thermostat in your engine, the two have nothing to do with eachother. If there is no air at all coming out the vents, I suggest it is your blower motor.
