The resvoir is located on the passenger side of the car behind abd below the alternator. You have to reach down and feel for the cap. You will also need a long funnel to make it possible to add the fluid.
Where do you add power steering fluid on a 2003 Pontiac Bonneville?
The Pontiac Bonneville used the same power steering fluid from 1992 until 2005. You should look for GM Power Steering Fluid with part number1050017 for quart sizes or part number 1052884 for pint sizes.
This is two of the things I know that could be wrong. The power steering pump is either bad or there is no power steering fluid in the pump causing it to have steering problems. Be sure to check the fluid level in the power steering pump.
Behind the strut support bar, behind and under the alternator is the power steering cap. It is difficult to get to. Good luck!
