        You need a wiring diagram for your specific vehicle to trace the common point(s) that power both your windows and radio.
        My brothers 2001 Monte Carlo had several electrical issues that occurred over a couple of weeks.
        Horn stopped working, blinkers not functioning, head light, cooling fans stopped working, etc
        Turns out several of the harness grounds had corroded.
