Welcome to JustAnswer, my name is XXX XXX I'm here to help get your problem resolved. You need to remove the plastic cover under the engine, air cleaner housing in engine compartment, and then you can also remove the plastic liner in the wheel well to give you more room. Most common things to seize up is the alternator and ac compressor...Once you have cover removed under engine and fender liner you will be able to see all the pulleys and check which one does not move. You can also install a new belt then turn engine with pry bar/breaker bar on crank pulley to see what pulley does not turn. Here is a diagram of pulleys and belt routing. Let me know if you have any questions, thanks.
