Our outside temperature display on our dash now says zone 9, not the outside temperature, on our 2002 Ford Explorer. How do we fix it to display the temperature again?

Did you by chance check for DTC'S diagnostic trouble codes?

A heater core is a component inside the HVAC box (located under the dash) that is heated by engine coolant. Vent temperature is increased by routing air through the heater core before it comes out of the vents. The temperature requested by the HVAC control module determines how much air passes through the heater core and how much air bypasses it. This event is called air "mixing" or "blending" which refers to the hot air and cold air ratio. Air routing through and/or bypassing the heater core is carried out by the use of a blend door and blend door actuator. Over time these two components can fail mechanically which often results in abnormal noises and improper positioning leading to undesired temperatures. Now, higher-end A/C systems with dual-zone climate control have multiple blend doors and actuators; this is how how the two different temperature "zones" are achieved. A failure with only one of the zone's blend door/actuator would result in desired temperature out of one zone's vents and abnormal temperature out of the other zone's vents.

This may be a wiring issue as the sensor is electronic in nature. Any loose wiring may cause the voltage across the sensor to differ resulting in an inaccurate reading.

Dear Madam or Sir,

if your Ford is equipped with a two-zone automatic climate control, the problem can be a defective temperature flap servo motor or a faulty signal from the driver´s side indoor temperature sensor.

The system can easily be checkt with thediagnostic computer at the next Ford branch.

sounds like the temp/direction sensor under the hood is worn out

if it is reading wrong al the time , replace the sensor. if reads off after car is driven sensor might have been moved to a spot near something warm and needs to be put back

Take the dash apart and replace the small bulbs. Also you can buy the Chilton Book from any Advance or Auto Zone for around 19.99 and it will have step by step instructions and pictures of any repairs that you may ever need on your vehicle. Hope this helps

I believe he's referring to the blend door actuator..Its a small white box maybe 3x3inches with gears internally, they tend to strip i just replaced mine its a pretty big job...I hear you can replace the actuator without removing dash but I was not able to without removing dash. its located down and left of the stero... you can special order part from auto zone..I believe the part number was 604 207...found a lot out about the job online and also from chiltons wasa big help.

the sensor is located inside the air intake tube

remove dash and replace bulbs. if you are handy and remenber where the screws go you be ok
