Hi,
Since we lost power at the interior fuse box, we need to work backward to see where power comes from.
If you look below, I attached three pics from the power distribution fuse box so you can see what is happening. I started at the AC power supply, pic 1. Note the supply powers other components within the same fuse box.
Power is received at the J connector, highlighted, so I worked back to see where that took me. See pic 2. Note the output (J) goes to the affected fuse box. Power to it goes through the ignition switch and is provided at circuit C.
I continued and found power is from the 60-amp maxi fuse in the left maxi fuse box under the hood. See pics 4 and 5 to locate the fuse.
Check that fuse. I suspect it will be bad. Let me know what you find or if you have other questions.
Take care,
Joe
