As others have stated my cruis control would work fine until I tried to go up a hill or use the acceleration button. Once I did one of the two my cruise would kick off and not be usable again until I shut the truck off. I looked at my Vac. lines and found a hole in the line going under the driver side battery. I was like great I found the problem and fixed it quickly. I test drove the truck and to my dismay the problem is still there. All of this happend yesterday, I didnt look at it again until this morning but I inspected all of the lines and there are no more holes anywhere. I disconnected the line that I replaced yesterday and upon disconnecting it I heard a hisssssssss from a vacuum still being on the line so I guess the pump is working and the lines are hole free. Is this normal? When should the pump run? And also what is that thing that the 2 lines are going to under the driver side battery? Thanks in advance for the help

Iv had this problem for a while. I changed the APPS after it went bad and it helped the problem some. While watching my Edge moniter throttle % I know it kicks off at about 30% throttle. I never have time to mess with the pump or lines to try and fix it. On highway trips I keep it the Smarty on tq3 and watch the hills so I can turn the cruise off before it reaches 25% (never gets that high though). So I'm good to go until I have time to fix the lines.
