Hello there.
The cruise control on my 98 V70R seems to be inoperative. Can anybody out there suggest where I might start looking for a (hopefully) cheap and easy remedy. It's not that I need it or use it regularly, but it would be nice to have it fully functioning. I knew my way around my old 240GLT estate, but this new technology gets the better of me!

Thanks in anticipation,
Steve.
