Bad compressor clutch locking up, or compressor lock up completely.

Most likely at this point is to replace the compressor.

^^ if the external clutch failed in a lock mode AND the belt burns that is definitely a compressor failure.

The Toyota TIS site has lengthy TS guide on what needs replaced depending on how far the debris traveled in the system.

In short a failed compressor can be very costly as the shrapnel travels throughout the system and IF every little particle IS NOT removed, compressor #2 will have a very short life!

OP - go into your heating control and turn off the A/C and/or with the engine and its belt off, confirm the pulley spins freely.

FWIW - take it to a shop who will stand behind there work for at least a year or 10,000+ miles because if they miss something, think expensive replay!

Gonna +1 this. I wouldn't deal with a failed compressor myself for the shrapnel reason alone. There is no other reason the compressor keeps killing your belts other than the compressor/clutch has failed. I'd be impressed if the compressor is still cooling somehow though (not sure where you are in Louisiana, but I know it hasn't been warm enough lately to run it anyways)
