Landcruiser 120 year 2005 burnt 40A fuse. Light short circuit smoke in cabin on passenger side.
Found burnt fuse (40A) PTC-2 in main fuse box on engine bay. Air condition did not work anymore.
What electrics parts (40A) PTC-2 protecting. Do we have Landcruiser 120 year 2005 electrical schematics available some where?
What do I need to check next?

PTC-2 is Viscous Heater. Where are you, do you have that option?

Have you had the trim out on the passenger side to see where the smoke came from? There are a lot of sensitive ECU's over there.

The viscous heater is usually located around or on top of the engine and has a clutch. Hence the large power fuse. this will give you an idea. https://www.roughtrax4x4.com/blog/viscous-heater/
