there may be a problem with the temp. blend door or the actuator that controls it.
The blend door is not fully opening and closing properly. I'm not sure about your model, but on some you may be able to get to the lever under the dash to manually move the door all the way or the other. On the explorer of that year there is an actuator motor which moves the door open and closed. They are of cheapo plastic construction and the teeth on the gear tend to break.
Heater blows heat for 45 seconds then warm air if I switch to AC it warm?
