There is a switch relay that plugs behine the ignition switch cylinder.You would have to take apart the dash console to take it apart to replace it.Also helps solve a few problem on the 2001 chevrolet impala, with heat gauage not working and a/c not blowing cold air anymore.Replacing it, should fix the problem with that.

Had same problem on my 2000 Impala and my 2001 monty carlo on the impala it was the locking mechanism from the transmission was slightly worn there is an adjustment under the dash to lengthen the pin slightly. The monty I had to change the ignition switch behind the key. U can try alittle light oil or WD 40 in the key hole it may help. Ignition and switch not cheap. It is not too hard too change if your a little mechanical and have a couple hours.
