I bought a 2006 Grand Prix for my wife to use as a work car last week and while trying to diagnose why the cruise control doesn't work I noticed that the hose/tube in the attached picture is cracked in a couple places where it connects to the motor. I brought it to autozone and the guy working the counter looked at me as if I brought in a piece of the Mars Rover. He finally got out of it by saying they don't carry the part and that I need to go to Napa, without ever telling me what the part is. I truly don't think he knew. The guy at Napa said he thinks it's a PCV hose but said that only dealerships would carry it. Can anybody tell me what exactly it is, or better yet a part # so I can order one? Is it true that I can only get it from a dealership shop? Thanks in advance for any insight you can provide.
