Cruise Control Issue on 01

Hello all i have a 2001 limited with Cruise Control well i have never really used the CC so on recent highway trip i went to use it and nothing happened no lights nothing. Does anyone know what it could be? Fuse? if so where is the fuse? Or could it be the buttone maybe? If so how do i check that out? Thanks Guys

Maybe a vacuum problem? The cruise works by using a vacuum.....check for leaks.

start with the fuses, then check for the vacuum leaks

the CC is on the passenger side of the fender behind the battery, its a little black egg
