Question about 1999 Ford Explorer

1 Answer

Temperature Control not working on 1999 Ford Explorer

When selection is Max AC, the air blows COLD, all other vent selections, the air blows HOT. The temperature control makes no difference. The air blows only COLD (max cold) on Max AC and HOT(hotest) on all other settings.

Thoughts?

Sounds like your temperature actuator is not moving or your temp door is broken. On max a-c ,coolant is shut off to your heater core allowing only cold air in.

    Check to see if the temperature door is moving. Lower the glove box ,the actuator is on top of the case .With a light look and see if the door moves when a-c is on and the temp lever is moved.

1999 temperature control will not regulate heat/air


This is likely caused by a failed or jammed electric air temerature control blend door actuator and or a warped and jammed blend door.

1997 ford explorer xlt. max ac works fine but when i switch to normal ac or change vent control it blows out heated air. How do i check or repair?


The blend door actuator is probably bad in it causing the warm air to blow out instead of cold air. It is behind the dash.

It may take several hours for a technician to get at it and replace the parts required for it to work again.

The AC was working fine one minute then started blowing very hot air, the compressor is still cycling through but it is still blowing hot air out of the vents


In the box that is mounted evaporator and heater is a gate that operates with vacuum and the temperature selector is opened and closed to pass the airepor the evaporator or the heater

There is a Flap on heater box and on some of those it is motor controlled, but it sounds like the flap is not switching back and forth

This car has the automatic temperature control system


The hot/cold switch is probably bad.you have a blend door box that opens to let the cold air in and closes to let the hot air in.From what you are saying this part is no responding to the switch movement.Make sure power is at the switch and power should go through the switch when put on cold air this moves the blend door.Some times the blend door goes bad and has to be replaced its under the dash on the right side.

Ac blows hot air ac compressor is ice cold but the vents blow hot air when enige is hot. bloows cold air when engine is cold


check your air diverter doors, sounds like the door for heat is open, when a/c is selected the doors should move and close the heater off. the heater will over power the a/c. the door controller is located on the environmental station under the dash neat to the floor. the control is electronic and probably not functioning
