TODAEG9

I just got a 2000 DC2 Front end and i swapped all the things(also the harness and the dash) into my EG9...The car now runs fine but there have something strange about the AC system..
When i parked it over night and the engine was cool, the AC system was normal,(my defi gauge show under 90 degree)the bump work,condensor fan run...everything is ok! ...but when the water temp reach 9X degree
the radiator fan have to run to cool it down right?in this time the ac still normal and very cool!but something strange started to happen...when the water temp drop and it will cut the radiator fan...but it also cut off my ac!The whole system were stop working..in this moment when i switch the ac button in my car it will no response....but when the water temp rasied up to 9x degree,the radiator fan have to run to cool down..the ac will work again..but when it drops..the radiator fan cut off...the ac will no response....why?

and i noticed that the radiator fan and the condensor fan will work together...that means when i switch on the ac under 90 degree...the radiator fan run also!normally it will only run the condensor fan right?as i remember EG9 should be run it individually....i don't know integra will work together or not..i think i have some problems between the EG9 harness and the DC2 harness...i have to fix it because it's getting hotter and hotter now(HONG KONG)...

CAN SOMEONE HELP ME?
