I have a 2002 grand prix I have read around the site and got great information. I just want to be clear, For every 10 times I shut my car off maybe 4 of of 10 times the key will not turn back allowing me to remove the key. I know that when it does this it's in park. But I don't hear the clicking at the dashboard, that's how I know It's not going to release. I'll usually keep going into different gears playing around with it until it clicks at the dash and the key will come out.
This has already costed me a few minutes of running late...I now know about the hole at the bottom of the column that will release the tumblr.
My question is what causes this , the ignition switch or the gear shift wires....I have read around that they may need to be cleaned or checked for bad connections/wires?
