Interior Electrical Problems!

What is your question?

I've got some really strange problems and could use someone with your expertise. First, the Traction Control and ABS lights came on all of the sudden. Then, a few days later, the Radio and Steering Wheel switches went totally out. After driving a while they (the Radio and switches) will start to work again. Then I noticed, whenever I try to open any of the 4 Windows from the Drivers side switch, the Radio and S.W. Switches go out again and come back on shortly. It occurs with less and less time delay between working and not working as the car warms up in 30 minutes of driving. But as soon as I even try to open a window,,,bamm they go out again. (And the windows don't work at all during all of this. Even if operated from their own door switch. So I tried disconnecting the battery overnight and reconnecting it in the AM. Nothing changed EXCEPT my Fuel Gauge swung all the way around clockwise until it hit the plastic stop post and its been there ever since. (So now it doesn't work anymore either). All the fuses under the hood are OK. (I've checked 3 times) I'm thinking that I've good a POOR ground wire connection somewhere,,,, but WHERE?? What on earth is going on?? Any ideas!! Any of your help would be appreciated. Even if you can just get me pointed in the right direction. Thanks Much!!! Kris
