Here's the write-up on the ATC issues off of cool cats.

Mine sometimes blinks after about 5 minutes of driving and resets when I turn the car off. Although I may take 40 or so trips at a time without any problems. It's just weird.

By the way, I see it's your first post... Welcome!

Its probably a Connector you didnt replug or a blocked actuator when remouting....
Check codes...

When i did my core, i forgot to replug one of the connector  on the box which hold the core....

I had that code as well. I went to the Ford dealer and asked what it meant. My answer was a prompt "I dunno" :dunno: So I lived with it and a couple days later the lights were not flashing anymore. A week later, they started flashing again and once again in a matter of days stopped flashing. Now it only flashes occasionally like I said before, after 40 or more trips. It then goes out again. Have no clue.

Try using your heater in the warm weather to see if you get the flashing.  I turn mine on at leaast once a week to cycle fluid through my heater core and the only time it has ever flashed is when the temperature is really low.....  Leads me to believe somethins getttin stuck when it's cold outside.  Whenever I test for codes I get none....

Cool, I've got a buddy down there. His wife owns "The Reel Deal" used clothing store in New Minas, in the old theatre building. My sister used to live there too, behind the Ford dealership at exit 14.

Glad to have another Nova Scotian on board. We now outnumber the Newfoundlanders :D
