Sterring Issue

I have a 06 Trailblazer with a 4.2. I am having an issue with turning right, when I turn right 75% of the time it feels as if there is no power steering, happens at pretty much any speed, from turning into driveways to freeway ramps. This doesn't happen when I turn left. What would be my best chance to start troubleshooting this. Power Steering Pump, Steering box?
Thanks in advance.

Your 2006 Trailblazer has rack and pinion steering. Since the problem occurs only when turning one direction, you most likely have a problem with the rack and pinion.
