So the air is getting distributed in the cabin, but it's not being heated up first. This could be a variety of different things, for the most part you'll need to hook the car up to a computer or diag machine in order to diagnose the problem. A diag computer may tell you an error code.

Then again it may not, because there are no lights on on the dashboard. For the most part  it's likely a better idea to take the car to a mechanic. It could be the heater core, but hopefully it's something smaller and not the core. A new heater core will cost hours of work and hundreds of dollars.

Another alternative to spending hundreds (and possibly more then a thousand) dollars repairing the problem would be to use a 12v heater for your car or truck. The 12v heater will generate warm heat inside the cabin, and then the fan will move it around. This may be a low cost alternative to
