In the engine bay there is a fuse block in front of the fan shroud.
There are fusible link fuses in there. Look for the 20A fuses, I think it's #51 or 52, maybe #10. You can see which one it is since these fuses have a window on the top.
Be prepared to pay $3.50 to $5 per fuse.
I just had to replace three of mine since a power inverter I was using blew 3 of my 4 12v power points.
