I just used the difference tool in TunerPro and compared a 9C1 file with a TA file and didn't see anything that I thought would keep the a/c from working. Its possible the files you are using may have something a little different.
Both of the files I used were for 94's and I downloaded them from http://www.gearhead-efi.com/Fuel-Injection/showthread.php?335-16188051-and-16181333-PCM-Information-EE-EEB.
