I have an 02 - 2x4 Excursion with the 7.3 liter diesel in it that is having climate control issues. I did the EATC self test and it throws out code 42 - Intermittent Ambient Temp Sensor Short. This makes sense, because the symptom is that you have to run the temp setting all the way down to 60 degrees before the blend door will shift and start blowing cold air.

The question is, where are the various sensors for the EATC system located on an excursion? The search feature brings up nothing, neither does good ole google. Some one here has to know. Thanks in advance!

 

Nobody knows?!?

Not a deezle guy, but didn't so looking around for you, hope this helps some.

 

IIRC, the ambient temp sensor is connected to the white tube running under the dash. if you look at the driver's side dash, to the lower right corner of the steering wheel, there is some vent slots molded into the dash plastic. If you pull the fuse panel cover and look underneath, you will see this white/gray hose that connectis to that vent. Somewhere along that hose is the sensor. It pulls air from the cabin to sense air temp. Hope I'm right/hope that helps.
