hey i have a couple questions my abs brake light is on, if i get it rebuilt and put back in will it go away as soon as i put it in or what? and i was woundering how to take out the entire cup holder in the center console because i got out the flip up part but theres still like the box of it in the center console, anyone no how to take the hole thing out? and whats the relay for the gas tank and where does it go or how do i install it?because i replaced the sending unit and the float and my gas tank still reads empty so maybe its the relay?
thanks
