Bear with me folks, I am a newbie and a chick....need I say more? We have 2 Grand Prix vehicles. One is a 1997 that runs like a scalded dog but the bells and whistles as well as cosmetically well, she has seen her better day. The other car is a 2002 in absolute fine working order all except for the ECM brain. A mechanic told us that it just wasn't communicating and could just need to be cleaned or replaced. My 2 part question is this...where is the ECM brain located on both models? We would like to clean the one on the 2002 to see if that worked. If not, we were going to see if we could put the ECM from the 1997 in the 2002 and then just send her to her final junkyard destination. Wouldn't that be possible if the two part models are interchangeable? We just need to know where to find them. I appreciate any and all help and suggestions. Have a wonderful day!!!
