A system fault is indicated by a flashing indicator. If there is a problem with the ambient sensor, in
vehicle sensor, or the feedback potentiometer, the Ext. Temp. indicator will flash for about 60 seconds,
upon ignition ON. The flashing indicator will reoccur upon ignition ON until the system problem has been corrected.
If you disconnect the battery and reconnect it, the system will recalibrate and move the door from one extreme to the other and then position the door and stop. The blower motor also comes on and you can manually turn it off. Takes about 30 seconds.
To enter the diagnostic mode, push and hold the fan up and down arrows at the same time for about 5 seconds.
The display should show "-00".
