When I bought the car (2001 SLK 320) last fall the cruise was working fine. After the first really cold day, it stopped working. Now that summer is here, sometimes it works and sometimes it doesn't. When it works, it fails when there is any stress such as going up hill. My tires are correct and there are no blown fuses (or I guess it wouldn't work at all). I just spent a small fortune at the body shop and I don't really want to spend a lot on speculative mechanic work. I really need cruise to help keep my speed down to a reasonable level.:crying: I can't afford any more tickets.
