This is not thirdgen related, but the moderators (and many others) on this board know their stuff, so I came here. I own a 97 Jeep Grand Cherokee and the cruise has quit working. The light on the dash illuminates when I hit the "on/off" switch, but when I hit the "set" button, it does not hold the speed. Any idea's?

 

Vaccum lines to the cruise should be checked and make sure the vaccum reservoir has no leaks. Could also be a vaccum servo gone bad.

 

thank you
