2004 Jeep Grand Cherokee. Interior lights won't dim and go out & elect wind won't work til they do see details

When int. lites dim and go off then the power windows & locks work perfectly. It's getting worse as the lites stay on longer and longer & can't open windows. The locks on the passenger side do work even when lites are on. The remote will then lock the passenger & 2 rear but not the drivers door. Also if you turn the int. lites off manually at the dimmer switch, it saves lites from burning but won't release the electric windows and locks. Sometimes when you open the driver door the int. lites don't come on & then they come on when you turn the key either way. Also when you put key in ignition it makes a continuous beeping noise that won't go away if you turn left to auxillary, but it does go away when ignition is turned on. So now whenever this beeping noise is there the windows/locks don't work & you know that the lights are still on or their switch is engaged.

Only way power windows/locks will work is if the interior lights dim & go off by themselves. All other electrials work fine.
