You'll have to get someone to trace the circuits to find the short. You can unplug the master switch in the driver's door and use a circuit breaker in place of the fuse or a fresh fuse. Toyota door switches have a history of problems. If you disconnect the master switch and the new fuse or circuit breaker does not blow, I would try another switch. You may also have a problem with the wiring harness between the door and the post. If the new fuse or breaker blows, you will need to disconnect the other motors and switches or look for a short in those circuits.
Does it blow the new fuses immediately? If so, the lighter socket is the more probable short circuit location--remove the center wire from the back of the socket and recheck. If no help, remove the power wire at the radio and recheck again. If neither helps, then there is the possibility of a wire short in the wiring harness or under the fuse panel. If the fuses didn't blow, then look for a burned/loose connection under the fuse panel. Did you smell anything burning or getting hot while trying the fuses? There would be no reason to include a circuit breaker in series with a fuse for protection. Good luck!
If there is nothing on the inside of your fuse box cover, the best way is to ground a test light to your door jam, turn the ignition on, and touch each fuse at the back on either side of the amp number where the metal shows through. You should have voltage to each side of the fuse. If you don't, it's burnt out.
This is not a fuse problem, it is a burnt out display backlight bulb, you have to pull the radio out of the dash and remove the top cover of the radio, you will see a tiny bulb socket, twist it out, replace that little bulb.
