The day that I bought my 560SEC, while on the drive home, the cruise control started jerking strongly and shut down. It would not work at all for the rest of the trip. The next day I tried to set it again, and it appeared to try to set up the shut down again. Since then I get no reaction from it at all. Checked the fuse, not the problem. Where do I go from here? Thanks,
mike
