One day the driver window wouldn't go up or down it was half way down. I noticed when I pushed the window button for either side the radio would shut off until I let go of the button. So I took door panel off put window up and didn't worry about it as it was winter. Then all of a sudden the radio quit working as well. Checked all the fuses and relays and all are good. What can the problem be?

You haven't included any test results to analyze, but based on the symptoms, probably the best place to start looking is for frayed or broken wires between the door hinges. If you find that, I'll describe how I handle that repair.

I checked the rubber boot where the wires go through and they all look to be intact. I also looked at the wires behind the radio and instrument cluster, heater controls and info center they seem good as well.

What is the symptom with the radio? Does it do it all the time now?

All electronic radios have two power wires; one for the ignition switch and one for the clock and station presets that is always live. How a radio responds when one of those circuits is dead depends on the model of the radio. Some of them will be totally dead. Some will have a display but no sound and no response from the buttons. Some even work fine but go back to 12:00 each time you turn on the ignition switch.

It is possible there is a problem in the radio, but given the additional symptom, it's more likely one of the power circuits is dead. Start by checking the fuses. Only one will be labeled "radio". The memory 12 volts will be tied into some other circuit like the horn, brake lights, or cigarette lighter.

The radio fuse is good I have checked all fuses and relays and they all are fine. That's where the issue comes into play why if all those things were good would this happen is there another way for me to run these two on a separate fuse or no.

There's WAY more to a circuit than fuses. The next thing would be to pull the radio and check for 12 volts on the two power wires. One of them is going to be missing unless the problem is in the radio.

I have no power to the ignition wire to the radio. I aslo have no power to that fuse in the panel or the sunroof or steering wheel controls. Is it possible the bcm could be going bad? Is there a wire diagram for the bcm so I can trouble it.

I'm having trouble following the wiring diagram. One radio fuse, (there's no way to tell which one), ties in with the steering wheel controls and other circuits, and they're all fed from another larger fuse under the hood. I'm pretty sure you're going to find one blown in the under-hood fuse box.
