There are no "blow-out plugs" on the A/C system; there's 1 overpressure relief valve, but I've never heard of one failing. Certainly not 2x on the same truck.
I suggest you start with the BATTERY TERMINALS. Click this & read all the captions:

I also highly-recommend that you get a Haynes manual & read it cover-to-cover at least once:
