I've searched and although their are a hundred threads about RFA problems, nobody seemed to know this question. What is the difference between the actual RFA module on different year C5's?
Basically, I have a '97 that had my RFA go bad, what year(s) can I replace it with?
I know their are differences in FOB's between 97-99, and then 2000, then 01+. But are those differences in the RFA module itself, or the fob?
