Question for experts 3

This is the third installment of my question. To recap my brake light and battery light come on when the car is on. They go off when the car idles and has been on for a while. Once the car gets reved the lights come back on. But tonight i found that when the car is idleing when the car is first turned on, if i hold down the window button after it is already down, the two go off, and they always go off and on together.

Wondering if it is my alternator cause when they go off when i bring the car to a light and bring down the RPM's you can hear it in the radio.

VERY IMPORTANT! check your grounds in your enigne bay.... second....check if any of your wires are burned causing them to short because they might be touching their opposite - or + ( check the alternator wires especially.. your last resort is to test your alternator
