Hello, I am new to this site. I tried to find the answer on this thread but I dont seem to see the answer. My cruise control lights work fine on the car. But when you take your foot off the gas the car slows down. I called the dealer, they told me to check the rear brake light and horn, but they work fine, so they say its not a fuse. Then they say come in, but its $109 for a diagnostic, then parts then labor. Ugh. Can anyone help with a step by step to find the problem, and fix it alone. Thank you ahead of time. vic.
