Key turns lock cylinder from OFF to ACC to RUN to
START, but will not return to the OFF position. This
may appear as an intermittent problem.
The ignition switch actually has two components: the
ignition switch and the ignition lock cylinder. The
problmes lies in the ignition switch which is the
large black portion that has two electrical connectors
plugging into it. This may be a known problem to the
manufacturer and the replacement parts should work
fine. No idea what actually causes this problem. Do
Purchase a new ignition switch from the dealer or
possibly a large parts carrier like NAPA.
At this time the Chevy Malibus are too new a model
to have this part carried at the local parts store.
The part should cost $151.22 (in Texas). A Chilton
or Haynes manual is helpful. To access the switch
use a screwdriver to gently pry out the bezel around
key/radio/AC console. Remove the two bolt head screws
around keyhole. You can now pull out the switch one
of two way from up top through gauges area over steering
wheel (HARD) or from below using small hands and removing
two plastic covers from pedal's area (EASIER).
