Why is my coolant leaking out? Help!!

[tomsC10R]

A few minutes after starting the truck, coolant starts leaking out of the heater box. Out of the two holes where the coolant lines stick out. What is wrong with it? Why is it doing that? I've never had to mess around with anything to do with a heating system so I have no idea what to check.

It's a non A/C truck. It doesn't seem like the heater even works. I can't hear the blower motor kick in. After the engine really warms up you might be able to feel a little heat and a little defrost coming out, but not much.

So what should I check? What do you think is wrong with it? Is it fixable or will I need a whole new something? Sorry for all the questions, anything will be helpfull!!

Thanks in advance
