I am having issues with the EATC module on my 2005 F150 Lariat. A couple of documents on this forum and others I have researched on the web talk about running pinpoint tests. My question is are you probing the wiring loom or the connector on the back of the EATC module for these tests? Thank You.

 

I'm having problems with my 05 also. The heater/ac blower will start then turn off right away. Ford said I need to replace the EATC module. I don't know where it's at. Any help is appreciated.
