Depends on where it is.... but if it is the seals in the pump gone, I believe you can rebuild yourself for under $100 - check with Chewy.....
the NA PS rebuild kit with bearing is about $55 in total from Nissan. Get the bearing from a bearing place rather than nissan as it will be cheaper. The seal and circlip come in one packet and the gasket with 3 x o-rings in another packet. You could do it cheap by reusing the gasket and circlip and then get the orings and seal from a bearing place also.
