Q: Reverse polarity jumped car, interior electronic don't work

Reverse polarity, at the battery, in a 12 volt electrical system on a car can cause a variety of effects including damaging the alternator, diodes and the numerous microprocessors on a vehicle such as those in the powertrain control module (PCM). As far as other fuses, they are numerous not to mention fusible links, circuit breakers, and all of the individual electronic components themselves in many circuits that could have failed due to reverse polarity. With regard to the circuits you have mentioned, namely the radio, dome light, power windows, park shift interlock, and the air conditioner, the best thing to do is simply trace those circuits to find the fault. It could be a fusible link, device fault or damage to a microprocessor based control or solid state relay. Simple circuit tracing, for example just starting with the dome light circuit will reveal the fault.
