Trailblazer
My 05 chevy trailblazer has a pump that is located
on the undercab of the driverside that will not shut
off when the car is off and is running down my
battery. It has two hoses coming from it leading to
the left side of my motor. As far as I can tell there
is air coming from one of the hoses, not a lot of air
so I'm thinking this is normal. Just need to know
what the pump is and how I can fix it
