Cruise Control Doesn't Engage.
 

Abour a week ago I got my 60K checkup from Nissan Dealer. Besides the usual stuff they check and change, I needed brakes front and aft. They changed pads and serviced the rotors. I picked the car up and drove it for a week. Everything worked fine. Yesterday I decided to use the cruise control on the highway. I turned the cruise switch on and the green light came on. I then tried to engage the cruise control using the button on the steering wheel. The cruise indicator on the dash lit up but started to blink.
The cruise control never engaged. I complained to the Nissan Dealer that the cruise control worked before I brought the car in. He said to bring it in and it will be checked out. After work tonight I tried it again on the highway (60mph) and it worked. I said "What da?". I disengaged it with the dash switch and tried it again after about 10 miles driving. It worked again. I disengaged it again by hitting the brake. I tried it a third time and, to my dismay, it would not engage. The cruise indicator on the dash just blinked away. Anyone ever have this kind of problem? Any help appreciated.
