I recently bought a '95 Caprice with the 5.7L lt1. Everything was working fine until this morning when I go to turn the car on. It turns on but the cluster is out, the ac won't turn on, and the power windows don't work. The radio still works. All of that worked prior to this morning. I changed the interior fuses associated with those things- numbers 11, 17, 33, and 42 and still nothing. Please help!
