I replaced the control unit (amp) last year and it seemed to work great. This year I took her out of storage, gave it a try and it worked on the HWY. Tried it again a week later and nothing, not even an attempt to engage
Coincidentally when it was working I was getting this odd "surging" while decelerating (with CC off) while coasting, almost like I was hitting the gas peddle.
That has since stopped along with the CC so it must be related somehow
