It could be that the vacuum hose that connects to your vacuum ball under your passenger's side front bumper is cracked. The cruise control needs good vacuum pressure to set. This happened to me last year: at first the cruise slowly lost speed, especially on hills. Eventually it wouldn't set at all, and when it got to that point another thing happened: my heater and a/c started only blowing out the defroster vents regardless of the setting. Since both cruise and vents were out, and both work with vacuum pressure, the issue was pretty easy to find. By the way, I researched my info on here and saved a ton of $$ in the process. Great forum!
