Why wont my power steering work on left hand turns, but it does on right hand? on 2005 Pontiac Grand Prix

The power steering does not work on left hand turns but it does on right turn. Could it be a malfunction in the rack and pinion? It doesnt cut in and out it just completely does not work on left hand turn only.

Steering gear will need to be replaced most likely. It is also called a steering rack by some folks. Cost vary depending if you go with a new replacement or a rebuilt unit. Several hundred dollars either way you go.
