I recently purchased a 2001 Limited Up Country and I'm attempting to repair things as I go along. My current issue is the cruise control. The cruise light comes on but it won't engage. My guess is that I have a leak at the vacuum reservoir. I have inspected the lines up to that point. How do I gain access to the reservoir? Do I need to remove the battery tray? Thanks in advance for any help.

 

The vacuum ball is inside your bumper. Take the end cap off and you'll see it.

 

Thank you Shaky.
