1998 Chevy Lumina Tail lights and window

Unless I'm mistaken, I believe there should be one lit bulb on each side (right and left) normally when driving. Do you have any lights from rear when driving?

That window/radio thing sounds strange. I'm not familiar with that circuit and I can't readily find a diagram online, but I wouldn't think anything associated with radio power should be run through the door/window switch.

Does the radio ever turn off/on when you're not operating the power window?

Does anything else strange ever happen when you're operating that power window - dash lights, heater/ac fan, lights? I think those power windows have a sort of thermal fuse in them, so that if you're trying to move the window and it's drawing too much power, that switch opens & the window will do nothing for a little while, until that switch cools & allows electricity to flow again. But it still sounds odd that it would power on/off just the radio. If it were affecting other circuitry, I'd expect there to be more involved than just the radio. And then again, I could hopefully be more help if I were able to find a diagram.

The radio only shuts off when you hit the driver side window button then you have to play with the window to get the radio to turn back on. The brake lights work when the car is in park but when you drive the brake lights do not glow. Only the light in the rear window
