radio, power windows and wipers only work intermittenly on 1999 Cadillac Escalade

for about 4 weeks - the radio, windows, and wipers are not working
items worked most of the time, now they rarely work
If I try and put the windows down - sometimes they work, other times the radio goes off and the windown doesnt work, when I press the window button, other times no response.
ON a 50 mile drive yesterday I left the radio on, and it may have played for a total of 10 minutes - in short 50 second blasts. then this morning I get in the care and wipers and radio work for about 2 miles

I HAVE A PROBLEM WITH MY 1999 CADILLAC ESCALADE, WITH MY POWER WINDOWS, RADIO AND WINDSHIELD WIPERS NOT WORKING AT THE SAME TIME. WHEN I START IT UP, EVERYTHING IS WORKING FINE BUT THEN AFTER ABOUT 30 MINUTES OF DRIVING THEY ALL STOP WORKING AT THE SAME TIME. SO I TURN THE TRUCK OFF FOR ABOUT 5 MIN. AND THEY BEGIN TO WORK FOR A FEW MINUTES MORE...AND NOW MY INSIDE DOME LIGHTS WON'T GO OUT...SOMEBODY TELL ME WHAT'S WRONG WITH MY 1999 CADILLAC ESCALADE.
