If the heater hoses for the front heater are getting hot, it could be a blend door problem under the dash.

First I would check your radiator fluid level, sometimes being low can have this effect. Usually the rear heaters sit at a lower level and so keep working. If that is fine, then you probably have an issue with the diversion door or controller that controls the hot/cold mixture.

Rear blower: only works on high when set on cold, won't work at all when set to heat


I would start with the rear blower motor resistor, the resistor is what controls the speed of the fan, the resistor is located in the rear heater box near the blower, you will need to remove the right rear side panel to access the heater box. start with that

A/c front blower is warm, but rear blowers are fine


This is a common problem and the solution usually is that the fron thermostat is usually gone and needs replaising. Shouldn't be too much money to get done. It's just not opening up to let the cold air pass into the from area but the rear one is working fine which allows it to blow cold air.

Explorer front air not blowing, rear blowing cold air


If the front is still blowing air but not air conditioned air than it is likely that a flap that controls airflow to the front has failed. The rear would still work as it is controlled by an auxiliary control.

If there is no air coming out of the front at all I would suspect a blower motor as the rear has it's own blower.

Either way a scan tool that is able to access the HVAC system is going to be the only to accurately diagnose this problem.

Front air condition does not blow cold. Rear air condition does


sounds like a damper door in the front not working properly, these are actuated by the front temp control, the door is operated by either a manual cable, and electric actuator, or vacuum. I hope this helps you zero in on your problem. Merry Christmas
