Hello all! I have a 2013 Expedition Limited. The problem I am having is, if the vehicle sits with engine off for more than an hour or so and it is hot outside, when I start the motor the External Trmperature will read 50 F. It seems to stay like that until the vehicle leaves cold loop, the the external temperature decrements until it reaches -40 F. Then, it increments up to the actual ambient temperature. During this time the HVAC will not work properly, until the displayed ext temp is sufficiently higher than the HVAC set point (as designed). The ect temp remains at the actual outside temp until the next time the truck sits for more than an hour.
I have replaced the Ambient Temperature Sensor.
Any other ideas as to what might be wrong?
Thanks!
