power windows and radio 98 pontiac grand prix gt 3.8L

1998 Pontiac Grand Prix

I am having an issue with the power windows and the radio. One day the driver window wouldn’t roll up and then i noticed that pressing the button made the radio go off until i let go of the window button. The radio now cuts in and out on its own and the windows still don’t work. Its a coupe model if that makes any difference. I was told to check the bcm and the rap. Just wondering if anyone has any other suggestions or has had this problem. Thanks in advance to any info.


The window motor/regulator is the most likely reason the windows are not working. But with the age a wiring issue wouldn’t be totally out of the question.
