I have a 1998 buick century ac compressor brand new but it's a 1999 compressor. it kicks on and off when it wants, don't know what's causing the problem. I've checked relay and blend doors, both sides were working, but now only the passenger side works when it does kick on. Is it ok to put a 1999 buick century ac compressor on a 1998 buick century and not have any prob? Please help!
