The A/C hasn't worked for a couple of years. I took it to Ford and they couldn't find the problem. The EATC now has no display so I cant control the heat. I checked the fuses and they are all fine. I would meter the harness going to the unit but have no wiring diagram. Any suggestions would be greatly appreciated.

Are you refering to an automatic temp control (ATC)? Air change sensor (ACS)? I'm not familiar with an EATC. Let me know what it is you are working on and I'll look for wiring schematics for you.

It would be the ATC, this car uses an electronic one opposed to a manual. Thanks again.
