| | intermittent window/radio power
may be of some help. worked for my problem. the power windows and radio would turn on and off by itself. when replacing the front speakers, we had noticed that the power door lock switch (pins) had quite a bit of corrosion on them.
we cleaned them up re-installed them. it seems to have fixed my problem on my 97 Trans am. im hoping that this is all that needed to be done. hope this helped someone.
