there are several things that it could be, the thermostat ($35), the heater core($150), or it could actually be the head gaskets ($110), or it can be a vacuum problem($30 Replace lines). the pricing is if you can do the work yourself, its parts only!

Another cause, especially with with ac working ok, is that the temperature blend door actuator / motor has failed.

This is a relatively common problem, and the repair is not too difficult. Autozone shows this part as only $15, and also provides an illustrated repair guide for the job.
