Car info: 1988 300ZX 2+2 NA2T running 87 turbo ECU

Not sure whats really going on here, but the title says it all. I think I've gotten the cig lighter squared away, as it appears to be broken (has now been removed), but the turn signal and audio fuses will still blow at the same time. The only common trend that I have for the fuses to blow is left turn signal on with acceleration.

My main questions are:
1. Why would all the fuses blow over a faulty wire/bulb in the turn signal?
2. Do I have a bigger problem than a bulb/wire?
3. It appears that the turn signal fuse also controls the A/C compressor clutch signal, as it starts working again when only the turn signal fuse is replaced. Is this normal?

Thanks in advance!

 

you should look at the EL section of the FSM for your model and see exactly all what is on those fuses, the little sticker in the kick panel doesn't list all attached devices... This will at least help you know where to look..
