If the blower motor isn't working, start by checking to make sure the motor is getting power. If it blows cold air, make sure the engine is warming up to normal operating temp. If it is, feel both heater core hoses with the engine running, hot, and the heater on. If both are hot, the blend door is sticking. If only one gets hot, flush the heater core.

As far as the noise, make sure all fluids are full in the differentials, transmission and transfer case.
