2005 Chevy Trail Blazer: Multiple electrical issues - rear windshield wiper turns on by itself, cycles one time (very intermitent). The voltage gauge is walking back and forth always. The interior lights do not come on with the door, but will turn on manually. With air conditioner on there is an occaisional draw down of power that almost turns it off. Radio resets clock only with each start. Lights dim when windows/locks are operated.
