Default Cruise control problem

ok prety much all my driving is done on long roads with no lights or stops, so i use my cruise control pretty much where ever i go. Yesterday my cruise control wouldnt turn on, i figured it was a fuse, but out of habbitt a few minutes later i tried it again while i was driving and it worked! On my way to work this morning i went to turn it on and again it didnt work, but after driving a few more miles i tried again and it worked fine, while it was on i turned it on and off, used the coast, accel, resume and all the buttons checked out fine. then pressed the clutch and brake in to turn it off, turned it back on and again it worked fine both times. When the cruise is on it works fine, no fluctuation, doesnt turn off, and like before all the buttons work. Its almost as if once the car gets warmed up it has no problems what so ever. When i got home i checked the cruise control cable, it has a little more slack then the throttle cable but i dont see that being the problem. Could it be a vaccum leak? Any of you guys have an idea of whats wrong? Recently the day before i sprayed the all under neath my car, wheels wells etc... with just a regular hose to get the NJ road salt off, could i have gotten something wet? Any help will be appriciated!

The cruise control has many inputs, some of them are the brake light switch, clutch switch, and speed input. The most common problem with cruise is a bad brake switch or it is mis-adjusted. Have you ever walked out to your car and your brake lights are on, or have you ever seen your speedo drop out? You can unplug the cruise connector and see if it is wet or corroded but it is unlikely that you got anything wet.
