Doesn't blow hot air
Your thermostat could be staying open,not letting the coolant to get hot,or your heater core is bad,usually leaking by driver side floor board.

SOURCE: Heater does not work
Check blend door motor for proper operation (vacuum operated) if necessary, detach arm from heater box and move by hand. If you have heat then, change motor! You are reaching operating temp for engine, right? If not, thermostat is stuck open... Change.

Hello: Check the coolant level, fill up the reservoir and run truck, if reservoir shows low again fill it back up. If reservoir was low/empty the check for leaks. Do this before you replace thermostat. The heater core would not create this kind of condition.
