The lights are on
In jak 2 there is a mission where you have to escort some of krews men through the sewers i know what to do but this mission is almost impossible i really need help
When I get stuck, I find there are several great written walkthroughs on GameFaq's. You can google Jak 2 Walkhrough and find all kinds of resources.
I try not to use the videos unless I absolutely have to, but I found this one on Youtube. It should help you.

Yea I would check GameFaq's like Mojo said, that is where I have gotten help when I have been crazy stuck.
