I'm not sure if the following are related but this is what happened: First, my A/C quit working, then a couple days later the headlights, dash lights, dome lights, turn signals, hazards, rear defrost all quit working gradually. I can manually make the turn signals blink by bumping the switch. If I try to use hazards, the bulbs all light up but don't flash. If I jumper the headlights to the battery they will light up. Temp gauge has now quit working as well... Fuses all seem good. I tried swapping the black square (relay switches) out under the hood, one at a time, but nothing changed. I also tried swapping the headlight switch out with a spare but that didn't help either. This is a police interceptor model. Power locks and windows, Radio and heater still work!
