'03 locks/windows/radio/door remote problem!

Hi everyone! New to AF, and love the sight.
On my '03 4.8L Silverado, these things happened at the same time:
1. The door lock/unlock remote doesn't work (replaced battery couple of months ago).
2. The passenger side window & door locks will not work from either driver's or passenger side controls (driver's side works fine).
3. The radio will not stay on when I turn the key off, like it should. It turns off right away.
The fuses all look good. Are there any other fuses on the truck, or could it be some kind of relay problem?
Thanks!

check the body grounds remove clean re-install...

j cAT,
Thanks for the response. Where would I check for the body grounds? Never done that before.

check all points where wires with lugs connect to the car body/frame in the engine compartment under the dash under the driver seat out side at the frame rail...

disconnect the battery negative terminal first before removal of these grounds clean and re-install...

also make sure the fuses are tight in the sockets ...many wiggle the fuses to remove this damages the socket so as to cause intermittent issues as well...
