My 2005 Cobalt LS. has a fuse in position 27, I believe, inside the vehicle on the passenger side, that keeps blowing. At first i thought this was just for the dome light, but this fuse appears to work the interior dome light, the push button for the truck opener, and the dinger when the door is open with the keys still in the ignition among other things. I have pulled the trim off the C pillar and along the floor, but I don't find anywhere the wiring appears to be shorted. Can anyone tell me where this wiring runs under the dash to look further for a fault or other potential problem causing the fuse to blow?
