Heater not working...

My wife has a 97 ford explorer V8 awd that had the heat stop working. It worked on the way into town, but when she drove it home it was cold air. Any ideas as to what I should try and how I can trouble shoot it?

Was the temp gauge operating normally (mid range)? If it was reading low, it could be a stuck thermostat.

Just for the heck of it check your coolant level. Might be low, & cold enough out side for you not to overheat. JUST MY .02

Another thing to check, if the heater hoses are not hot and the engine is up to temp, check the vacuum operated bypass valve.
