hello, I have a 99' taco. The heater in it went out for no reason. I checked coolant levels. They're fine. I checked thermostat...it's fine. The heater fan works...it's just not hot air. I'm guessing it's the heater core....i just wanted to let you guys know before I take it in. I usually check all the inexpensive things out and troubleshoot beforehand. give me the knowledge....
