2000 Ford Escort Q&A

2000 Ford Escort Question: MY A/C ISNT WORKING SO CAN I REPLACE THE 2000 PCM WITH A 1997 PCM

what does a 2000 pcm control on A 2000 ford escort and if i replaced it w/1997 pcm what would it control on a 2000 ford escort I was told that 1997 WOULD MAKE THE A/C NOT FUNCTION PROPERLY IF ANY AT ALL AND BY CONNECTING THE 1997 TO 2000 COULD CAUSE IT TO JUMP TIMING AND THEREFORE IT COULD HAVE CAUSED A VAVLE SEAT TO DROP IS THIS A FACT OR POSSIBLE? -
