Headlights: If you
can find someone to swap relays with,
put your headlight relay in their car. Do not put their headlight relay into your car. Reason: If there is something with your car that is frying the relay, your friend's relay will not get zapped. By putting your relay in your friend's car, you will know if it is the relay or something else with your car.
AC/Heater blower: After you check fuses, check that the 2 wire connection (under the hood and under the flimsy plastic wiper motor cover) to the blower is connected to something. You can also connect a small amp battery charger to the connection to check the blower motor. From there, I would definitely move to relays.
Cigar lighter fuse: Fuse chart shows that the fuse is common with instrument lights. I would venture a guess that someone has wired the cigar lighter with the power connected to ground. It's pretty easy to remove those connections to the cigar lighter from the passenger side of the console. See if that doesn't cure your fuse issue on this circuit.
Passenger side window switch: trace the wire from the switch to the connector. Some new switches don't come with the multi-terminal connector attached. Check for the multi-terminal connector. If it does not have one, chances are it was just wired up wrong. If the multi-terminal connector is present, that should reduce the chances that it was wired up wrong. If this is the case, I've noticed that the newer switches sometimes seem to get "stuck" and can be unstuck by rapidly tapping on the "up" side and then the "down" side in a somewhat forceful manner with one finger. I know it shouldn't be this way, but I've noticed sometimes that it just works.
