Ok... well I replace a DCCV because once in a while my pass. side would start blowing hot air. After the replacement it hasnt happened yet... both sides blow cold and warm air when needed and the temp. changes just fine... however... when set to cold my driver side is blowing cooler air then the pass side .. (maybe by about 2-5 degrees difference) when its set to hot the drivers will still have a little bit cooler air coming out (again about 2-5 degrees). Is there a AC thermostat? or do you guys think that it is going to be DATC? The difference in the temp is not that bad and I guess I could live w/ it but just checking. Thanks for your input.

At this point in time, I think you're looking at some very sophisticated diagnostics needed to determine your problem. It could be something as simple as a blend door or it could be in the electronics. The dealer should be able to pinpoint this for you. Alternatively, it's possible the DATC may be able to help diagnose this for you. A lot of vehicles use that to show codes, etc for the climate control. But honestly, I don't know if this car will do that. A service manual would be required.

For DATC self diagnostics press OFF + PANEL and then AUTO or OFF + FLOOR and then AUTO. In one case it will show codes that are stored in the memory, if no codes all DATC symbols on display will come on. In another test it will count from 1 to 25 and then show codes if found, if no, then all symbols on the display will come on. From this test you can exit by pressing any button, from another one you can exit by pressing windshield defrost. After those tests all codes will be erased. Only thing I do not remember whitch button combination was for whitch test

Ford says up to 10 degrees difference side to side is normal and should not be considered a defect.
